The belt conveyor roller could adopt the black rubber belt, which could be used for transporting materials in bags, sand and gravel, coal briquette and etc. Most EPC companies could realize the positive and negative transportation through increasing gib block below. Besides, we could realize the transportation of bulk materials by adding the dam-boards. The roller is the important part of the conveyor. The roller has many types. The quality of roller directly influences the quality of conveyor. The roller determines the performance of conveyor and service life of conveyor. The structure of roller set confirms the load bearing of conveyor.  The basic requirement of roller includes reasonable structure, wear well performance, better dustproof performance, good waterproofness and reliable performance. The bearing should have good lubrication, light weight, small steering resistance, low fabricating cost and smooth surface. The function of roller is supporting conveyer belt and th...

The development of modern logistics is the precondition of creating and development of automated warehouse , which is suitable for the development of industry and technology. The modernization production promotes the socialization, specialization and specialization of production. The mechanization and automation require that the supplying of goods and materials should be timely, quick, and accurate. In this way, the development of automated warehouse is promoted. For the arrangement of space, we should make classification first, knowing the using direction of each location. Then we should assess the importance and design the layout. If the space is limited not changing the planning and design, we should let the present space's use ratio fully used. The requirements of goods shelf are high. The appearing of automated warehouse drives the development of goods shelf. Good automated warehouse should follow the principles as below.  The high performance and low cost is considered....

The main faults of reclaimer focus on the bucket-wheel and running mechanism. The bucket-wheel component of each reclaimer includes reclaiming hopper, wheel body, rollaway nest, chain wheel, tension device, actuating device, supporting roll, side roll, supporting wheel of trolley. The main fault form is the sharp wear of supporting wheel and supporting roll. The reasons and solutions are as follows: The water content of materials is large. The freezing of base and material pile would result in the rapid change of materials. The solution is making the reasonable proportion to the dry and wet materials, reducing the freezing of materials base.  If the clearance adjustment check is not done timely, the interval will be over the standard.  The solution is measuring the interval in regular time. If there is something wrong, we should arrange the related persons to make adjustment or make replacement.  The rollaway nest surface evenness of wheel body exceeds the standa...

The conveyor belt is the bearing carrier and traction component of the belt conveyor(not including steel wire rope traction). The conveyor belt should have the carrying capacity and enough strength of extension. The framework and coating make up the conveyor belt. The coating is divided into upper cover glue, edging glue, and below glue. The framework of conveyor belt is made up of various fabrics or steel wire ropes, which are the backbone layers of belt bearing the total load of working. In this way, the core materials of belt should have enough strength and stiffness. The coating is used to protect the core materials from damage of harmful medium. The upper cover glue is thick, which is the bearing layer of conveyor belt. It directly contacts the materials and bears the impact of materials. The below glue is a contacting layer of belt and idler, which bears pressure. In order to reduce the resistance, the below glue layer is thin. The edging glue could protect the belt core materia...

In general, the apron feeder could be divided into three types including heavy, medium, light type, which is the continuous transportation machinery widely used in mining, metallurgy, construction materials, ports, coal and industrial and mining enterprises. The apron feeder is mainly used as the storage bunker to continuously supply the materials or transfer large material to crushing machine or batching apparatus. The apron feeder is one of necessary machine for handling materials in the process of continuous production. Sometimes some EPC companies would choose stacker reclaimer, belt conveyor, stone crusher and etc to complete the transportation of materials. The light apron feeder is suitable for transporting materials under 160mm granularity in short distance. It is used for continuous feeding in mine, mill plant, chemical industry, cement, building materials. The light apron feeder could be installed horizontally or obliquely. The maximum inclination degree is 20, which is su...

The stacker reclaimer is a continuous bulk materials handling equipment, which is widely used in port, metallurgy, cement, steelworks, coking plant, coal factory, power station and etc. Sometimes, the stacker reclaimer coordinates the belt conveyor, apron feeder to complete the materials handling process.  The center pillar is regarded as the center of cantilever stacker. One end is steel structure belt conveyor and the other end is balance weight. The stacker is connected with rotation device, realizing the rotation through the engaging between small pinion of rotary actuator and gear ring of large bearings. The materials entering into the round yard would be unloaded to the stock ground through the head of cantilever belt conveyor. The materials probe is set in the two sides of discharge opening. If the top surface of material pile touches the probe, it shows that the material pile has reached the designed height. The pitching of hydrocylinder is adopted by stacker, whose ad...
