Reasons for deviation: first, the front and rear rollers of the conveyor are not parallel or wrong; Secondly, sundries are sandwiched between the belt and the roller; Thirdly, the distance between the middle idler and the vertical roller of the conveyor belt is large, which leads to uneven stress when the belt falls; Fourthly, the sweeper inside the belt or the leak-proof baffle at the entrance is worn, resulting in uneven stress. Reverse smelting method: 1. Adjust the adjusting bolt so that the front and rear rollers are parallel and opposite; Second, clean up the sundries between the belt and the drum; Three, reasonable arrangement of rollers, vertical rollers, keep the belt stable, uniform stress.

Even; Four, timely replacement of sweeper or baffle.
