One reclaiming operating line with two bucket wheel stacker reclaimers is mainly used in the coal blending working in wharf, which belongs to belt conveyor mixture coal blending method. The fetching and coal blending means that the coals are stored and fetched by two reclaimers. BQ1 and BQ2 will be allocated with one reclaimer. Finally, the materials are transported to the ship loader. If the coal blending demand and reclaiming proportion is different, the reclaiming with low reclaiming proportion will have underloading situation, which results in the energy waste.  "One belt, two machines" layout could obviously avoid the light running of belt conveyor. After comparing the advantages and disadvantages of different layout, most wharfs will adopt "one belt, two machines" layout. One reclaiming operating line with two bucket wheel stacker reclaimers has been widely used in the wharfs of coal blending such as port of Qinhuangdao, port of Tianjin, port of Huanghua,

The circular stacker reclaimer is one kind of equipment which could do homogenization treatment, storage, and transportation of materials. The circular stacker reclaimer is made up of column structure, main beam structure, travelling device, rake, trolley, cantilever belt conveyor, platform railings, transmission and etc. The circular stacker reclaimer is one of the important equipment in cement plant, which could complete the stacking and blending reclaiming work of limestone. Besides, other material handling equipment will be adopted by most EPC companies. to coordinate it such as apron feeder, screw conveyor, pipe conveyor, stone crusher and etc. The circular stacker reclaimer plays an important role for the advance homogenization, stabilization and quality of clinker for the limestone. The circular stacker reclaimer integrates the stacking and reclaiming function. The circular stacker reclaimer has three components including stacker, reclaimer, and center pillar. There are two

With the economic globalization, the bulk cargo terminal plays an important role. Our company optimizes the design of bulk cargo terminal to increase the operating efficiency and reduce the cost.  The bulk cargo terminal is one important part of handling system and also the place where the materials are stored. The optimizing of the belt conveyor system could increase the flexibility of stacker reclaimer , increasing the use ratio of stock yard. In this way, the operation efficiency could be better, realizing the energy conservation and efficiency of storage yard.  According to the characteristics of bulk cargo, the loading and unloading line is divided into 3 types including stacking line, reclaiming line, and combined line. According to different processing layout, the belt conveyor system will be collocated with different handling machinery such as stacker, reclaimer, apron feeder,  pipe conveyor and etc. In generally, one belt conveyor system is arranged with one handling

At present, the main problems of automated warehouse include low use ratio, unobvious effects, uncertain scale, unobtrusive advantage, which makes many storage resources idle. The reasons are mainly showed in following aspects:  The diagnoses working of warehouse construction and plan is not completed successfully. There is no necessary research and analyzing. After completing the construction of automated warehouse, people will find that the use ratio is so low.  People has poor understanding for the warehouse mechanization and roboticized idea. The lack of understanding and reluctance of using equipment make people stay in the stage of manual operation and have no confidence in the automated warehouse. In this way, the automated warehouse's research and usage are abandoned inwardly.  Although the change of external factor and turn of events, the warehouse equipment and management system have not related change and upgrade. As time passes, it will lose the original market,

For the impact stone crusher , the periodic maintenance working is very important. The stone crusher must be lubricated periodically. The machine should be checked before starting and after stopping. When the daily maintaining is completed perfectly, the stone crusher could have sufficient application.  The lubrication of impact stone crusher: Before starting the impact stone crusher, the moderate lubricating grease should be added between brackets. The selecting of the lubricating grease should be according to the using site and conditional decision. In generally, the calcium-based and sodium-based lubricating grease are adopted. The lubrication could guarantee the normal running and prolong the service life of stone crushers. The lubricating grease added into the bearing pedestal should be changed every 3 months. When changing the oil, the clean gasoline or kerosene should be used to clean the rollaway nest of roller bearing.  The usage of impact stone crusher: After the s

The screw conveyor is a kind of equipment which uses motor to drive the screw to rotate. The screw conveyor could transport the materials in horizontal, inclining, and vertical direction. It has many advantages such as simple structure, small cross sectional area, good sealing, easy operation, simple maintenance and etc. During the actual operating, there will be some problems. The reasons analysis of some problems are as follows: The conveyor screw axis would stop rotating. In generally, there are three reasons. The materials handled are too large. In this way, the materials could not get through the hanger bearing, which increases the resistance and results in the load running and machine halt. So the materials must be cleared.  The resistance of middle bearing has large resistance. The sealing is easy to be damaged. If the materials enter into the bearing, the halting and damaging of bearing will occur.  The bearing of reducer is damaged. The bearing temperature of redu

The belt conveyor is widely used to transport the loose materials because of large delivery capacity, simple structure, low cost, easy maintenance and other features. Especially in mining, the belt conveyor has wide application. If the conveyor belt break, the belt will slide for many miles, which would break up the idler, pipe, rack cable, and small parts. If serious, the belt and materials will form bulk deposition, which would result in the halt production. The reasons of belt break are as follows: 1. The gear reducer is damaged. The fluid coupling has hydrojet phenomenon. The changeover of electromotor is also one of the reasons. 2. The conveyor belt joint has something wrong. The conveyor belt joint is divided into mechanical splice and vulcanized joint. The quality of mechanical splice is worse than that of vulcanized joint. So the application ration of mechanical splice is small. For the vulcanized joint, if the vulcanizing temperature and sulfide stress are not controlled

The jaw crusher is the common stone crusher . As we all know, the working environment, materials characteristic and other performance have influence. Therefore, the jaw crusher's maintenance work should be according to the operating process, which could prolong the service life of jaw crusher. How to choose the suitable lubricating grease is one of the important operational capacities for the operating personnel. The matters needing attention are as follows: Selection of lubricating grease: The jaw crusher's working environment is different, which needs different lubricating grease. In summer, outdoor temperature is high. So the No. 70 lubricating oil could be chosen. In winter, the No. 40 lubricating oil is suitable.  Lubricating Mode The bearing and eccentric shaft of large and medium jaw crusher adopts force-circulation lubricating. If the oil pump breaks down, the jaw crusher needs swinging power for 15-20min and then stops. The hand pump needs be used to give oi

At first, the pipe conveyor is accepted because it is a form divided from universal materials handling forms. Now the pipe conveyor is standard. The pipe conveyor is the best solution for transporting grain materials. The application of pipe conveyor is unlimited. If people could think, the pipe conveyor could solve it. We think that any materials could be transported by pipe conveyor. The common materials used by pipe conveyor include mineral, coal, coke, limestone, macadam, shale, alluvium and etc. Some materials could be transported by pipe conveyor such as steel concentrate, petroleum coke, clay, waste residue, concrete, metal, coal ash, tailings, alumina and dust filtration.  The pipe conveyor's obvious advantage is turning in minor radius, which could reduce the silhouette. The pipe conveyor is restricted by surrounding idlers. So the pipe conveyor will not have the off-tracking phenomenon, compared with the common belt conveyor . The pipe conveyor could curve in vertic

The automated warehouse has many advantages such as land saving, high storage efficiency, timeliness and veracity of store management and etc. The automated warehouse is widely used by most EPC companies . In order to complete the design of automated warehouse, the related persons should do following jobs: 1. demand analysis They should conclude and analyze the demands and data of buyers to determine the design objective and standard.  2. confirmation of cargo unit and specification According to the research and statistical result, the related person should confirm the reasonable unit and specification. 3. confirmation of parameter of apparatus The automated warehouse has many forms. In general, unit cargo form is widely used. According to the technological requirements, the related persons confirm the operating type and parameter of apparatus to choose the suitable handling equipment.  4. model building The related person should confirm the layout of warehouse. 

As we all know, the lubrication is very important to the equipment. The lubrication could reduce friction and protect the equipment. The main functions of lubrication include lubricating, cooling, rust protection, cleaning, sealing, buffer and etc. 1. reduce friction and wear Through reducing the friction, we could reduce the wear of mechanical parts and other moving parts, prolonging the service life of moving parts.  2. cooling function The flow of abrasive could take away the heat produced by running. In this way, the equipment could work in reasonable temperature.  3. rust protection After lubrication cover the surface of mechanical friction, the surrounding medium could be avoided to touch, preventing the corrosive function. 4. washing function When the lubrication flows, the dust and related grains could be washed. In this way, the wear could be reduced.  5. damping function The rigidity of lubricating oil is small, which has damping function.  6. sealing
