一、概述在磨矿分级循环中,磨矿机排矿(见图1)中小于分离界限粒度的颗粒(简称为细粒级或合格产品,下同)能否及时而完全地分离出去,以免过磨,而其中的大于分离界限粒度的颗粒(简称为粗粒级或不合格产品,下同)又可否不被分离出来,以防“跑粗”,关键在分级设备。

First, an overview In the grinding grading cycle, the ore mill (see Figure 1) is less than the separation of the boundaries of particle size (referred to as fine-grained or qualified products, the same below) can be promptly and completely separated, so as not to Over grinding, and which is greater than the separation of the boundaries of particle size (referred to as coarse or unqualified products, the same below) can not be separated out, to prevent “running rough”, the key in the grading equipment.
