The speed of discharge of a coal washing equipment determines the efficiency of coal washing. So if you want to improve the efficiency of coal washing equipment, you should start from the root. Improving the discharge device of coal washing equipment directly affects the efficiency and quality of coal washing.

　　The selected coal washing equipment discharge structure is a impeller discharge device, which can stabilize the washing water movement at the discharge port and has good control performance. However, the impeller type discharge device often experiences blockage and jamming accidents. The coal washing equipment uses a multi chamber shared CNC air valve technology and a conical slide valve, which is reliable in operation, reduces failure rate by 70%, and has low energy consumption. It can meet the sorting needs of different media, improve processing capacity by more than 20%, and have a more reasonable structure for transportation and installation. The equipment load is reduced by 30%, and the power is reduced by more than 70%. In the 1970s, a new coal washing equipment discharge structure was developed, which installed the original impeller on the outside of the discharge channel, leaving a certain distance away from the material corner. In this way, when the impeller is not rotating, the material resting angle can be used to stabilize or reduce the discharge of underflow products. If necessary, the impeller speed can be controlled according to the bed signal to adjust the discharge amount, achieving an ideal continuous discharge system.

　　When choosing coal washing equipment, first check the efficiency of the discharge device? Then order coal washing equipment according to the needs.
