conveyor belt pulleys suppliers

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.
