Conveyor Belt Pulleys Suppliers

Tongxiang are eperienced conveyor belt pulleys suppliers in China.Belt conveyors are widely used in the transportation of materials such as ports, coal, power plants, etc. The conveyor drum is a key component of the belt conveyor, and its function is to transmit the torque provided by the drive device to the conveyor belt.Depending on the load of the drum, the drum can be divided into a light drum, a medium drum, and a heavy drum.The light drum is welded, that is, the web is welded to the barrel, and the hub and the shaft are connected by a key.The medium and heavy drums are cast-welded, that is, the web and the hub are integrally cast,then welded with the barrel, the hub and the shaft are connected by expansion sleeves.The advantages of the expansion sleeve connection are: accurate positioning, large transmission torque, easy disassembly and assembly, and avoidance of axial swaying.The surface of the drive drum is covered with rubber or ceramic to increase the coefficient of friction between the drive drum and the conveyor belt.Due to the heavy bearing capacity of the medium-sized drum and the heavy-duty drum, the design calculation is unreasonable, and it is easy to cause accidents such as the broken shaft of the drum. Therefore, this paper will use the example of the transmission drum designed by our company for a mine to design and calculate the medium-sized drum and the heavy-duty drum.

The belt conveyor drum in underground mining with double drums drive are common.When the transportation volume of coal is large and the transportation length is long or the inclined transportation is adopted, the conveyor driving device has the dual-roller common driving rigidity and the double roller driving method.Through the derivation of the traction distribution of the two drums under the dual-cylinder common driving mode of the belt conveyor, the influence of the actual diameter deviation of the two driving drums on the traction ratio is discussed.And in response to the above effects, the double drum co-driven belt conveyor drum wear.The belt conveyor drum and belt in contact with the outer bread brazing or with the countersunk rivets riveted layer of high-performance wear-resistant steel plate, strong roller wear resistance.The calculation of the drive drum plays a very important role in the manufacture of the conveyor drum, but the manufacturing process of the conveyor drum can not be ignored. Frequently, the drum wear is serious, causing frequent damage to the drum, which seriously affects production.The belt conveyor pulleys wear of a double drum co-driven belt conveyor is often associated with load imbalance caused by changes in the diameter of the two drums.For example, the heat treatment technology of the shaft, the non-destructive testing method and the processing quality all determine the life of the conveyor drum. The purpose of the rigid connection is to enlarge the traction angle. This method can also use multi-machine mobilization. When the motor fails to work, use the synchronous wheel. Therefore, in order to obtain high-quality products, the calculation must be accurate first, the design should be reasonable, and the processing technology must be guaranteed.
