The tension devices are the important parts for belt conveyors, to know the tentioning device function clearly is good for conveyor daily operation. And what are the functions for the belt conveyors? SKE machinery will show you the detail:

(1) Ensure the sufficient tension of the separation point of the belt conveyor driving pulley , so as to ensure that the driving device relies on the friction traction force that must be transmitted by the friction transmission to drive the conveyor to operate normally.

(2) Tension must be ensured for load separation, limit the sag of the conveyor belt between the idlers, and ensure the normal operation of the belt conveyor, so as not to cause slippage, deviation, etc. due to the slack of the conveyor belt .

(3) Compensation for plastic deformation and changes in the elongation of conveyor belts in transitional conditions. Because the load change will cause the conveyor belt to change in length, and the creep phenomenon will also cause the conveyor belt to elongate, so the tension force changes, and the position of the tension roller must be adjusted frequently to ensure the normal operation of the belt conveyor.

(4) Prepare the necessary travel for the re-joint of the conveyor belt. Each belt conveyor has several joints, which may cause problems on the street at a certain time. It must be truncated and redone. At this time, it can be solved by loosening the tensioning device and rejoining.
