选择性磨矿研究概述

Review of Research on Selective Grinding

选择性磨矿是指多种矿物组成的矿石在磨矿过程中,由于矿物与矿物之间硬度的不同,致各矿物的破碎程度不同的一种磨矿现象。论文基于选择性磨矿现象和应用,介绍了物料性质、磨矿机械、操作条件等因素对选择性磨矿的影响规律,认为合理调控选择性磨矿影响因素对于提高磨矿效率和优化磨矿产物粒度组成具有重要意义。

Selective grinding is a grinding phenomenon with the different crushing extent of the minerals for the difference of the hardness between the minerals in the grinding process. Based on selective grinding phenomena and applications, the effects of material properties, grinding machinery and operation conditions on selective grinding are introduced. It is obvious that regulating factors of selective grinding reasonably has an important significance for im- proving grinding efficiency and optimizing size composition of grinding product.
