Large fluctuations in the feed pressure During the production process, the feed pressure will affect the processing capacity and grading particle size of the aggregate crushing value conclusion.Generally, the feed pressure of the aggregate crushing value conclusion should be stable as required, and no large fluctuations should occur, otherwise it will damage the performance of the equipment and affect its classification effect.In addition, if the aggregate crushing value conclusion has a long period of violent shaking, it also indicates that the aggregate crushing value conclusion is clogged. If the overflow and underflow flow are reduced, it may be that the feed port of the aggregate crushing value conclusion is blocked.At this time, close the feed valve blocking the aggregate crushing value conclusion, remove it, and clear the blockage; If the underflow flow is reduced or cut off, the underflow port is blocked. At this time, the flange can be removed to remove the debris in the underflow port.In order to prevent clogging, facilities for preventing coarse materials and debris (such as chip removal screens) can be installed in the feed tank of the aggregate crushing value conclusion group.
