Many customers require plastic bag on the drum, the reason is that package (cast) plastic material on its surface can reduce cable knot to prevent the conveyor belt deviation and wear. Here I come to you with details about plastic drum kits causes and effects.

          In the interior of the drum drive motor load reduction mechanism Lee called electric drum. In the use of low-power conveyor electric drum is very favorable, can simplify installation, reduce the area of the entire drive, light weight, low cost, there are significant economic benefits. However, due to poor motor cooling conditions to work inside the drum fever, often due to seal damage caused by leaving the motor oil into the motor burned out.

         To improve the lack of electric drum, people crossing the design and manufacture of the gear reduction, ie internal load only the drive roller gear reduction mechanism. It is compared with the electric drum, not only to improve working conditions and maintenance of motor conditions, but allows it to transmit power has increased greatly. Idler pulleys used in conveyor running people to change. There used to tighten belts, glass stone crushing to make it in a blanket on the drum remains constant angle. Hammer Crusher bend pulley only under pressure, do not transmit torque, structural Lantern special requirements. Idler pulleys with steel rollers and glossy light bread (cast) plastic drum.

         Package (casting) of plastic material intended to reduce the knot on the surface of the cable, to prevent the deviation of the conveyor belt and wear. Drum diameter belt conveyor design, correct and reasonable sampling drum diameter has great significance Yin belt usage conditions, but will make the weight, drives, speed reducer transmission ratio increased accordingly. Try not greater than the conveyor belt to ensure normal conditions of use desired value. Diameter increases can improve Therefore, in the choice of the drum drive pulley diameter should be considered when Yin diameter tape around the drum due to bending stress generated; conveyor surface pressure ratio; cover rubber or tread deformation; conveyor subjected to bending the frequency of the load.
