1.The traction force of the belt conveyor with large inclination is transmitted through the friction between the drivepulley and the belt. Therefore, the belt must be tightened with a tensioning device so that the belt has a certain initial tension at the separation point of the drive pulley.
2. The belt runs on the supporting ilders together with cargo. The belt is both a traction mechanism and a load bearing mechanism. There is no relative movement between the cargo load and the belt, which eliminates the frictional resistance between the belt and the load during operation. Because the idlers are equipped with rolling bearings, there is rolling friction between the belt and the idlers, so the running resistance is greatly reduced, thereby reducing the power consumption and increasing the transportation distance. For a large-inclined belt conveyor, its traction force transmission capacity depends on the belt tension, the wrapping angle of the belt on the drive pulley, and the coefficient of friction between the belt and the drive pulley. It is necessary to ensure that the belt of the large-inclined belt conveyor does not slip on the drive pulley and run normally. In production practice, corresponding measures must be taken according to different situations.
