It is a common problem that belt conveyor will appear the phenomenon of feed casting.And the reason is multi-aspect.The most important thing is that we should emphasis on its maintenance in daily life.
1.Feed casting in the transferring point.This kind of situation will be happened in the hopper and guide chute.If belt conveyor is overload,it will result in the damage of keep-off rubber apron board. We can solve this problem by controlling the conveying capacity and strengthening the maintenance.
2.There is feed casting when concave section of belt conveyor suspends in midair.The reason why concave section of belt conveyor suspends is that curvature radius is smaller. At this time, the situation that belt conveyor becomes groove will change. Because belt has departed trough roller unit, the groove angle becomes smaller that will result in the phenomenon of feed casting. Therefore, we should adopt the larger curvature radius as far as possible in the design stage to avoid happening this kind of situation.
3.When the belt is off tracking, it will appear the phenomenon of feed casting.The reason is that the height of two edges changes when the belt is running.Thus,one side of belt is high while the other is low. And the n the material will drop out from the lower side. We can adjust the belt running deviation to solve it.
