The ship loader is a kind of large bulk-material handling machinery for load-out operating. In general, the ship loader consists of belt conveyor with cantilever crane, belt conveyor for transition, flexible chute tube, tripper car, travelling device, portal frame, tower frame, pitching device, slewing device, and etc. The ship loader plays an important role in energy, electrical power, metallurgy, port and etc. The ship loader could be operated with continuous ship-loading in general. So the continuous material flow must be provided, such as the continuous feeding of bucket wheel stacker reclaimer in stock ground of coal wharf. The development of trade integration promotes the demand of handling bulk materials. The seaborne volume of iron ore, coal, grain and etc is rapidly increasing. With this development, the continuous renewal of ocean transport ship occur. Accordingly, the demand of bulk material handing is increasing with continuous development. The ship loader manufactur

The sweeper, as one of the conveyor components , has played an important role in conveying materials of belt conveyor. According to the actual processing conditions, if the attachment adheres to the conveyor belt. There would be two negative factors. If the attachment adheres to the belt, the belt conveyor would convey another materials with attachment, which would result in the bad quality of the another materials. This is not allowed for the strict quality requirements. Besides, the attachment would do damage to the belt conveyor. When the belt conveyor transporting the materials and some materials could not be cleared by sweeper, the residual materials may enter into the shell of the roller. As a result, the radial load and axial load of the bearing block would become large, which would increase the abrasion of the bearing. If the attachment enter into the bend pulley, the surface of the pulley would adhere to more and more materials, which would result in the belt deflection and

As we all know, the stacker reclaimer , as one of the mining equipment, has many components. Among most components, the bucket wheel is one important component. The basic introduction is as follows: Bucket-wheel device is mainly consists buckle-wheel body, reclaiming hopper, frame, supporting roller, side catch wheel, driving sprocket, redirection sprocket, tensioner sprocket, adjustable arc stock guide, bucket-wheel driving device and other parts. The dual bucket-wheel device is installed on the main beam, the two bucket-wheel device are connected together by the bucket-wheel connecting beam. In running, the bucket-wheel body and the reclaiming hopper on it will rotate back on the main beam rolling with the wheel body center, and the trolley of the bucket-wheel device will drive the bucket-wheel body and the driving device etc. to reciprocating motion to excavate the materials on the main beam. The excavated materials by the reclaiming hopper will rotate back to the upper part alon

In the coal power plant, there would be dust in some place. The dust is resulting from the raising dust with wind blowing and handling coal of bucket wheel machine. In generally, there would be three methods of avoiding dust. The first one is spray dust-removal in sealing house, but the cost is high. The second one is adopting wind break wall, with disadvantage of high cost. The third one is using the spray gun to remove the dust, with advantage of low cost and high efficiency. However, there will be a problem of prior-period investment. If choosing large spray gun, the range and cover area is large. The quantity of large spray gun is less than small spray gun. However, the large spray gun has larger volume. The price of the large spray gun is higher than small spray gun. To balance this contradiction is difficult and important. The most important thing is the design of the spray gun, which needs designer to consider the earlier investment and the low cost factor. The spray gun is easi

Idlers, part of belt conveyor , are used for supporting belt and materials. They can be divided into transition idlers, groove idlers, groove forward-inclined idlers, impact idlers, v type forward tilt idlers, parallel return idlers and carrying & return self aligning idlers. Each group has features of advanced structure, light weight, small transmission resistance, good sealing and long life etc. When the belt conveyor is designed as the pipe conveyor , the idlers also have some changes accordingly. Transition idlers: Transition idler group is composed of 3 rollers, trough angle is respectively 10 degrees and 20 degrees. It is used for transition supporting belt near head & tail pulley. Trough forward tilt idlers: Trough forward tilt idlers is composed of 3 idlers with 30 degrees trough angle and 1.5 degrees forward tilt angle. It can protect conveying belt from swaying . Impact idlers: Impact idlers is composed of 3 rollers with rubber ring. They would be installed unde

The belt conveyor is the main transporting equipment for bulk materials. With the development of the industry and technology, the application range is becoming wider and wider. The future direction of the belt conveyor is long distance and large conveying volume. The belt conveyor has opened the bright prospect for the work of the transporting the bulk materials. 1. The belt conveyor design system for long distance is competing with the rail, ship and pipe transporting. The advantages of adopting the belt conveyor include efficient transporting, protecting the materials and good adaptability to the terrain. 2. About the drive mode, the obvious feature is the longitudinal dimension. The belt conveyor must be equipped with the enough drive capability if overcoming various resistances. 3. The cost of this kind of conveyor system is large with investment volume of millions dollars or even more. So it is so important to design the reasonable structure, which could reduce the running co

The forging technology could be divided into free forging, modular forging, rolling ring, and special forging. The free forging: Free forging refers to a method of forging where the heated iron/steel is anchored and then formed by hammering, pressing, or other methods. Free forging can flexibly form the shape of each product, and is suited to making large components or for diversified small-quantity production. The die forging: This forging method is suited for the production of industrial product components. The die forging could be divided into hot die forging, warm forging, and cold forging. The warm forging and cold forging is the developing direction in the future, which standards for the level of the forging technology. Rolling rings: The rolling rings refer to the ring-shaped work pieces with different diameters manufactured by special ring rolling machine. Some wheel shape pieces would be used in the automobile hub and train wheel. Special forging: The special forging

Belt Conveyor is widely used in the field of mining, metallurgy, coal, port, power plant and building material. It has the characteristic of high capacity, low power consumption, long distance transportation, low noise, environment friendly and low cost of maintenance. The scraper conveyor is a large-scale conveyor device, using scraper chain traction to convey materials. It is a kind of mining equipment . Sometimes, the pipe conveyor would coordinate with scraper conveyor. The scraper conveyor consists of hand piece, middle part, drive end unit. The scraper conveyor could be applied in horizontal transportation, also inclined transportation. If the scraper conveyor conveying the materials in upward direction, the coal bed pitch could not be over 25 degrees. If the scraper conveyor conveying the materials in downward direction, the coal bed pitch could not be over 20 degrees. If the coal bed pitch is very large, the anti-skid device should be installed. The principle of scraper conv

The portal scraper reclaimer and boom scraper reclaimer are the main types. The differences are as follows: 1. The portal reclaimer has reasonable structure. The partial weight of portal frame and scrapper reclaimer is supported by the wall(blocking materials). In this way, the stress state under the central cylinder, and the running of the portal scraper could operate smoothly. And the boom scraper reclaimer's load could be transmitted to the central cylinder. In this way, the design and manufacturing difficulty is large and the stability of the equipment is bad. 2. The portal reclaimer has compact structure, and there is no need to design the balance weight. The space occupied under the portal reclaimer is small. The boom reclaimer should be designed with large balance weight. 3. The portal reclaimer need the circle track in the wall(blocking materials), and the related cost of setting circle track. The balance weight load of the boom scraper reclaimer is central under t

The magnetic separator is widely used in resources recovery, lumbering, mining, chemical, ceramic industry, food and other industry. As one of the mining equipment, the magnetic separator is suitable for handling magnetite, magnetic pyrite, calcined ore, kibdelophane with granularity under 3mm. Besides, the magnetic separator could be used in the deironing of coal, non-metal ores, building materials. And the magnetic separator could be used in the coal power plant to filter the condensate water. There are many factors influencing the efficiency of the magnetic separator. The two main factors are as follows: The feed size is one of the important factors. If the feed size is small, individual separation of ores will be high, reaching the good separating index. Otherwise, the individual separation of ores will be low, making the concentrate grade worse. So it is important that the ores handled by magnetic separator could reach the degree of individual separation. The pulp density is th

Stacker reclaimer is one of the mining equipment, there are many types of stacker reclaimer such as portal, bridge and boom type. Here the features of portal and bridge type stacker reclaimer are introduced. The portal stacker reclaimer is a efficient loading and unloading machine, which is mainly used in stockyard for bulk materials. The features of portal stacker reclaimer are as follows: The lateral section of material pile is trapezoid, which increases the use ratio of stockyard. The large span could be realized easily, with the maximum span reaching 65m. The electrical control system is simple without frequency control. The hoisting mechanism adopts winding engine, with simple structure and easy operation. The automation of the equipment could be easily realized. The bridge stacker reclaimer is suitable for long stockyard, which is applied in port, wharf, mining, cement plant, coal storage yard, coking plant, power station and etc. The features of bridge stacker recla

The stacker reclaimer is one of the common mining equipment . It is developed from the bucket wheel excavator. And the travelling device of bucket wheel stacker reclaimer consists of driving carriage, driven bogie, equalizing beam, anchor, rail clamping device and other components. The limit switch is set with the travelling device. And the touch device is set in the two sides of the rail. When the limit switch touches the touch device, the power would be cut off. In order to avoid the situation that the boom of stacker reclaimer touches the materials pile, the travelling device could operates with high speed when the boom is paralleled with the rail. And this limit device is set on the slewing device. The position detector also be set in the travelling device, which could detect the location of the equipment. The detecting result could be showed in the operator's cab and central room, and then could be transmitted to the computer to realize the automatic control. The rail cla

For the burning active lime, the rotary kiln has the following features and advantages compared with other forms of rotary kiln. (1) In the course of the burning, the temperature of combustion apparatus is easy to control. So the quality of calcining is good, and the activity degree of lime could reach 350-400ml with low pollution. (2) The rotary kiln could calcine the materials with smaller grain size(over 5mm), increasing the use ratio of the materials. The products could be used in converter steelmaking without the crushing process because of small size of materials (generally 20-50mm). (3) The mechanization degree of rotary kiln is high, and the operation process is easy to control. The productivity is large, which is suitable for the requirements for the metallurgy, smelt and other large-scale industries. (4) The rotary kiln system has many machines with large weight. So the steel dosage is large and the investment cost is much. (5) The materials wear greatly in the rotary ki

The mining equipment is essential for mining enterprises. Mining equipment includes stacker reclaimer , belt conveyor, apron feeder, screw feeder and etc. If there is no mining equipment supporting the whole enterprise, the mining enterprise could not normally operate. With the development of the machinery technology, the requirements for mining equipment maintenance become stricter than before. In order to keep the normal operation of the equipment, it is necessary that the related people take measures to check the equipment in regular time. Especially for the EPC companies , they do better in machinery maintenance. The emphasis of machinery maintenance should be placed on the prevention of machinery fault. The timely correction is very important when faults occur. The contents of maintenance include the outer of the mining equipment , such as clutch, brake, safety facilities and other important components. Besides, the related people should check whether each device becomes flexibl

Most EPC companies will choose the pipe conveyor to transport the materials rather than the normal belt conveyor. The unique belt conveyor design of pipe conveyor enables the belt conveyor. The pipe conveyor is the special belt conveyor developed from troughed belt conveyor. It is developed through compelling force on idler sets to the pipe form, in which the materials are sealed in the pipe. In this way, the materials could be protected in the pipe and this pipe conveyor reduces the pollution to the environment. The pipe conveyor has the following features: (1) The pipe conveyor is similar to the normal belt conveyor. It is easier to be accepted to the most users. (2) The pipe conveyor could prevent the other things sneaking into the materials. According to its principle, the pipe conveyor could realize the sealing conveying, avoiding the materials escape in the course of transportation. (3) The pipe conveyor could be set in flexible way, realizing the space turning. In this w

1. The purpose and significance The belt conveyor is the main equipment handling the bulk materials. Belt conveyor is widely used in metallurgy, chemical industry, mining, power plant, ports and other industrial fields. With the development of economy and technology, the belt conveyor develops in the direction of long distance, large volume, high speed. Especially in the mining equipment field, more and more belt conveyors are applying in conveying materials. To reduce the investment cost of forwarding station, the belt conveyor with horizontal curves is designed and manufactured. 2. The development situation of belt conveyor with horizontal curves According to some statistics, a belt conveyor with horizontal curves was launched to working in Algeria iron mine site in 1970, with length of 2385m, lifting height of 121m, conveying volume of 1000tons per hour. A coal belt conveyor with horizontal curves was launched to working in South Africa in 1978 with length of 3.5 km. After

The maintenance of conveyor has a direct influence on whether the service life of conveyor could be prolonged. So this maintenance job must be important in the course of operating the conveyor. There are many conveyor components. If we know these conveyor components well, the service life of conveyor could be prolonged through the conveyor components . Conveyor roller(idler) is used to load the conveyor belt. It is the bearing component for the belt conveyor, with uniform cylinder form. In the center of idler(roller), there is a hollowed-out column hole, which is used to connect the bearing device of conveyor. The machining precision of idler means inner bore concentricity of idler and the precision of axial dimensions. If the dimension error of concentricity is serious, the bearing seizure of rolling bearing will occur, increasing the running resistance and reducing the time of service life. If the error of axial dimensions of parts is serious, the large axial clearance will form, r

The slewing bearing could support the large axial load, radial load and inclining moment, which is widely used in wind power generation, hoisting machinery, mining machinery, construction machinery, harbor machinery, marine machinery, national defense equipment, and other large-scale slewing device. For a long time, the assembly technique of steel ball and separate unit adopts manual assembly. The high labor intensity and low working performance create the failure of assembly quality. The slewing bearing technology is widely used in many fields. The stacker reclaimer is a technology product of slewing bearing. However, any product needs the daily maintenance. The auxiliary equipment is applied to inject descaling fluid in high pressure. That the stacker reclaimer rotates over and over again makes the relative movement of friction pair occur, cleaning the grime and duct depositing on the roller path. After that, the engine oil will be injected into the slewing bearing to clean th

As we all know, the belt conveyor has many ways of prolonging the service life. And a good belt conveyor design counts a lot. Usually the belt conveyor coordinates with the stacker reclaimer . There are keys to successful preventive maintenance that can be summed up in two words, “Good Housekeeping”. Good belt conveyor and idler maintenance begins with “Good Housekeeping”, the master key to getting the highest return on your conveyor dollar. We have found the following procedures play a prominent part at almost every installation where high standards of maintenance are achieved. They provide excellent guidelines for any operator. 1. inspection – The key is timing and who does it. It should be done daily and ideally performed by the Maintenance Superintendent or the Foreman. 2. prompt repairs – Repairs should be made as soon as possible after reported – daily if possible. 3. conveyor records – keep a brief outline history of each conveyor noting such things as the original

Although the bucket wheel stacker reclaimer has some advantages such as large radius, high capacity, low cost, environment friendly, the problems of it also exist. The feed rate is not insufficient when  reclaiming materials. The feed rate is that the onward distance of reclaimer, which is controlled by walking motor and controls the depth of reclaiming materials. In generally, there are two reclaiming speed. The onward distance is about 24mm when it is in low speed(200 t/h), while the onward distance is about 60mm when it is   in high speed(500 t/h). There is insufficient materials in piles. If the capacity of materials is large, the height of material pile is higher. In this way, the materials reclaimed be reclaimer is much more than that of small quantity of materials, which could increase the productivity of stacker reclaimer. Otherwise, the productivity of stacker reclaimer will be influenced greatly. When bucket wheel stacker reclaimer reclaims the materials, the equipment

The maintenance of conveyor has a direct influence on whether the service life of conveyor could be prolonged. So this maintenance job must be important in the course of operating the conveyor. There are many conveyor components . If we know these conveyor components well, the service life of conveyor could be prolonged through the conveyor components.

With the development of coal mine production mechanization, the belt conveyor is more and more widely used in the coal power plant. Then let us discuss some problems of belt conveyor design and some reformations. In the mine excavation, how to solve the non-interaction of conveyor and track conveying, reduce the cost of equipment? The good belt conveyor design is necessary. Because of the complex geological structures, there would be crossed roadways in the coal mine. Then the belt conveyor design should solve the difficulty of crossed lapping technique. There are two ways advised. The headstock of belt conveyor is transformed. Prolonging the roller support frame and increasing the height of headstock foundation realizes the control of height of conveyor belt and baseboard, achieving the purpose of no interference among conveying materials in rail and conveying materials by conveyor belt. The second way is on the basis of the first way failure. The end of belt conveyor would be l

The magnetic separator is one of the mining equipment. It is the main equipment in the production line of magnetic separation. The efficiency of magnetic separation is the hot issue for manufacturers and users. How to increase the efficiency is very important technological problem. There is some advice from NHI. 1. The usage of machine for blending material The magnetic separator completes the magnetic separation through the magnetic force. If the material layer is thick, the effect of magnetic separation will be bad. So the users could increase the magnetic separation efficiency through the machine for blending materials. 2. The height adjustment of material distribution board The height of material distribution board influences the effect of magnetic separation. When the height of material distribution board is low, the lean magnetite could not recycled better, reducing the use ratio of ore resources. When the height of material distribution board is high, the gangue mineral coul

The life circle of project could be divided into concept, developing, implementing, and ending. And there are five main processes of project management of EPC companies . The introduction is as follows: 1. Starting process of project The starting process includes project identification and starting. The leader of project should know the concept that the tiny success of important project has more significance and value that that of unimportant project. So the starting process is so important because the investment is determined in this stage. Emphasis on starting process is the first step to guarantee the success of the project. 2. Planning process of project The detailed planning of project scope, task decomposition, resource analysis should be completed in this stage, making the teamwork easy to carry on. According to the planning, we could complete the work more quickly and orderly. 3. Implementation process of project In this stage, the key points of the project are emphasi

As we all know, the apron feeder would always coordinate with other mining equipment (such as screw conveyor , long inclination belt conveyor, stacker reclaimer ) to realize the materials handling process. Then sometimes the apron feeder would have something wrong in the operation. Equipment failure Torque transmission fitting surface of transmission main shaft and reducer hollow shaft has relative rotation, resulting in abrasion of hollow shaft and shaft. Causes analysis 1. After long time operating, the metal would have metal fatigue, transforming from elastic deformation to plastic deformation. Then there would be gap of the fitting surface between shaft and bearing cone, resulting in the abrasion. 2. In the course of operating, the lack of lubrication and cooling leads to the heating of bearing, the increasing the running resistance, and the bending deformation of bearing. Traditional solution repairing welding：difficult installation, low efficiency, long period, high co

In practice, the slewing bearing failed in many aspects, such as larger load, abnormal impact, abrasion in raceway, noise increasing and other problems. The main causes of these problems include the installation of slewing bearing, stress of slewing bearing, and post-maintenance of slewing bearing. The installation of slewing problems mainly include quality flaw of slewing bearing. The overall quality of slewing bearing is better, but there will be some problems in transporting and storing, such as deformation in slewing bearing. The weak location of slewing bearing is broken. The ball track of slewing bearing is processed with quenching. Then there will be quenching weak area in the slewing bearing, where the hardness and intensity are poor. In this way, the failure of slewing bearing may occur because of this reason. Besides, installation accuracy of slewing bearing is bad. When the slewing bearing works, its end face and supporting platform should coordinate closely. If the f

Large machinery's detailed measures on preventing strong typhoon maximum wind velocity in the normal operation condition: 13.8m/s anti-wind device : 13.8m/s(maximum bearing capability) anchor: 28.4m/s(maximum bearing capability) administrative staff: They should arrange inspection and detailed examination, ensuring the good condition of anti-wind device of stacker reclaimer . The typhoon practice is carried out in regular time, making each operator of stacker reclaimer could operate various anti-wind device. maintenance personnel: They should do weekly check and timely maintenance, making the rail clamp and anchor flexible and feasible. They should guarantee the complete interlock with electric system. operator of stacker reclaimer: The operator should correctly operate the rail clamping device and anchor. The operator should pay attention to the operating conditions of swing brake and seriously fill in the spot check table. After finishing the operating, the large boom of

The life circle of one project could be divided into concept, developing, implementing, controlling and ending processes. During the concept process, the main items include cost analysis, and study of project feasibility. The purpose is to make a report and receive the approval and support. In the real work, most people just have an idea or a concept and then quickly turn to the developing process. However, during the developing process, the project planning paper, budgetary cost and job plan should be prepared for carrying out the work.  Most people carry on work with a general schedule of project and then finished the job. In the implementation phase, people should have a job plan and the fixed cost estimation. In fact, most people just regarded the stage as a project. Then at the end of the project, people would lose control because of no specific "milestone". So during this time, people would discuss the lessons of each project. But for the done work, people could not

The number of mining manufacturers is increasing year by year in recent years, resulting in the violent competitive situation. Many experts predict that the mining equipment will develop in the following directions.  Environment protection: The principle of low consumption and light weight is adopted by many designers. In the course of production, some harmful materials would be avoided. Some parts could be recycled as fuels. Large scale machines: For example, the volume of ball mill is 5-8 times larger than that last ten years and the volume of autogenous mill is 15-20 times larger than before. At present, there is a lot purchasing information for large-scale mining equipment, showing the demand situation of the market. Automation: The instrumentation and sensor for monitoring feeding capacity, pulp density or other measure parameters have been prepared basically. The difficulty is grade detection of various materials. Optimization design: The advanced technology should be

The advantages of EPC model are as follows: 1. EPC contractor is responsible for the implementation process of project. This could helps the planning and collaborative operation of the overall project. And many problems could be solved. For example, the connection problem between design and construction could be solved effectively, reducing the intermediate link between purchasing and construction. In this way, the contradiction among practicability, technicality, security could be solved also. 2. The limit between working range and responsibility is clear. And the responsibility and risk during the construction period could be transferred to the general contractor. 3. The total prices and duration of the contract are fixed. This could help the control of expense and progress. 4. The advantages of project management could be showed, realizing the various objectives of project management. 5. The owner could be free from the specific affairs and the pay attention to the import

Belt conveyor is a kind of equipment transporting materials through the friction drive. Different belt conveyor design could created different types of belt conveyor. Our company mainly has the following types about belt conveyor. Downwards transportation belt conveyor, plane turning belt conveyor, coal mine belt conveyor, pipe belt conveyor( pipe conveyor ) and other conveyor components are the main products of our company. Among them, the pipe conveyor is widely used in the metallurgy, construction materials, chemical industry, thermal power, ports and etc. It is mainly applied to convey ores, coals, raw materials, waste residue, and rubbish. The materials is conveyed in the pipe, which means the materials are conveyed in the closed environment. So the materials would not scatter everywhere. At the same time, the materials will not be polluted by the outer things. The change of weather will not influence the conveying of materials, realizing pollution-free conveying and red

A s one of the EPC companies , has the strict requirements in designing. Because the most mining equipment belongs to the non-standard products, this is a big challenge  to the designers. The designers should design related products according to many factors. Our company has an advanced belt conveyor. Especially for the screw conveyor, the designing level of JULI is higher than other companies. The belt conveyor, as one of mining equipment, is the non-standard product. The belt conveyor could be designed according to the operating environment and conveying lines. The key points of belt conveyor design are as follows: 1 The working environment and operating conditions The designer should consider the operating duration, working frequency , the service life of belt conveyor, and methods of loading and unloading. For the working environment, the designer should consider the environment temperature, the environmental requirements, and the flexibility . 2 The conveying lines and

With the practice of stacking and reclaiming materials in the new operation of top stacking and lateral reclaiming stacker reclaimer, long-range control technology is crowned with complete success.  Coal processing company now has 4 set of top stacking and lateral reclaiming stacker reclaimer. To solve some problems such as bad work environment and high safety risk, the coal processing company started to carry on technology improvement on remote wireless control in the second half of 2015. It do a mass of work about rebuilding feasibility and technology project argument. It finally confirm wifi technology through the consultation and technology communication. This could realize the purpose of long-distance control on equipment. This stacker reclaimer and belt conveyor together could reach automated process. The accomplishment of this project realize the respective operating function, improving the function of automatic protection. The working environment has been greatly imp

Crusher Load The crushers and ball mills applied in mining and construction use the converter to get the high efficiency. Large scale kiln load Ring kilns applied in metallurgy, construction and other major industries usually adopt direct current and commutator machine to adjust the speed. Because of the low efficiency, recently many enterprises use the converter to control the machine and get the good production. Stacker reclaimer load The stacker reclaimer is the main equipment in the coal yard, port, mining. The main function is stacking and reclaiming materials. The realization of self-motion stacking and semi-automatic reclaiming increases the equipment reliability. The equipment runs stably and it is without the impact and shaking. The relaiming process is with the rotation adjustment of 1/cosφ, increasing the efficiency of rotating reclaiming and the evenness of conveying coals. Many EPC companies would choose the converter, especially for the mining industry(i

Many users of mining equipment want to increase the efficiency of belt conveyor. The basic solution is good belt conveyor design. For example, we talk about the turning belt conveyor here. Turning belt conveyor is widely used by several industries because of its special function. The design principle of turning belt conveyor is different than the normal belt conveyor. The design thinking and principle are more complicated. Belt conveyor is mainly applied in the mining, chemical, metallurgy and other industries. In most situations, the belt conveyor is not set in the linear type, but in the conditions of certain curving. The middle of the belt conveyor may involve in mutual matching of various equipment. So we should consider the site layout of belt conveyor to complete the belt conveyor design, reaching the requirements of users. This kind of belt conveyor has the obvious advantage, that is high efficiency. For the most EPC companies, they prefer designing the turning belt c

As we know, apron feeder  is widely applied in many fields. So it is important to operate apron feeder effectively. So today I want to share some tips about how to maintain the apron feeder  to prolong the service life. For the maintaining of apron feeder , users should pay attention to the following points: A. The feed size  should be under the specified range . B. The avoidance of the direct impact of big blocks on wood casing . C. The progressive adjustment  of motor's speed governing must be adopted, avoiding the moment adjustment from low speed to high speed or from high speed to low speed. D. On the normal working conditions, the components and parts of apron feeder  should run stably and without the situation of impact, vibration, and oil leak. The highest oil temperature should be under 80 Celsius degree s and temperature rise  should be less than 60 Celsius degree s. Besides, the conveyor component s' maintenance is also important. Reducer is the impor
