砂泵在湿式选矿生产中是不可缺少的矿浆输送设备。但是,砂泵输送矿浆有扬送矿浆量(以下简称扬量)不稳定的弱点。这在我国选矿生产中,是一个很普遍的问题。主要原因是设计选择砂泵的扬量与实际生产中流量很难完全一致。一般砂泵扬量比实际生产流量大30—100%。如何解决砂泵扬量稳定问题?本人通过生产实践,总结出一种简而易行的改进方法——砂泵循环稳定法。其改进措施见下图。这种方法是在砂泵出 Sand pumps in the wet dressing production is an indispensable pulp conveying equipment. However, the slurry pump slurry delivery Yang sent pulp volume (hereinafter referred to as the amount of Yang) instability weakness. This is a very common problem in our dressing production. The main reason is that the choice of design sand pump capacity and actual production is difficult to exactly the same flow. Generally sand pump than the actual production flow 30-100%. How to solve the stability of the sand pump lift? I through the production practice, summed up a simple and easy way to improve - sand pump cycle stabilization method. The improvement measures see below. This method is pumped out of the sand
