The spreading of the belt conveyor is a common question, and the reasons for the PVC conveyor belt are also many. But the key is still to strengthen the usual maintenance and maintenance. Spreading material at the forwarding point Spreading material at the forwarding point is mainly in the hopper, guide trough, etc. The belt conveyor is seriously overloaded. The rubber guide plate of the material guide groove of the PVC belt conveyor is damaged. The steel plate at the material guide groove is planned to be far away from the belt. The rubber skirt plate is relatively long to make the material rush out of the material guide groove. The above-mentioned situation can be solved in the control of transportation ability and strengthening maintenance. Spreading material when the concave section belt is suspended. The conveyor belt of the concave section of the concave section belt will cause the belt to hang when the radius of curvature of the concave section is relatively small. The groove angle becomes smaller, so that some materials are spilled out. During the planning period, a larger radius of curvature of the concave section of the PVC conveyor belt should be selected as much as possible to avoid this kind of situation. For example, in order to shorten the tail truck on the mobile mechanical ship loader and stacker-reclaimer equipment, the concave section is planned to be an arc-free transition section. When the width of the belt of the PVC conveyor belt is small, the material is slightly spread out.
