磨矿是为选别作业准备物料的一个作业。选别效率与有用矿物的解离度密切相关,矿物解离度低,入选物料中将会带有大量的连生体,引起精矿品位下降和有用矿物流失,这是非常不利的。一般说来,磨矿产品粒度越细,矿物的解离度越高。但是细磨不仅要消耗大量的电能和原材料,而且还会引起过粉碎,致使有用矿物 Grinding is a job for preparing materials for sorting operations. Sorting efficiency is closely related to the dissociation degree of useful minerals. The degree of dissociation of minerals is low, and there are a large number of entangled species in the selected materials, which leads to the decline of concentrate grade and the loss of useful minerals, which is very unfavorable. In general, the finer the particle size of the grinding product, the higher the degree of dissociation of the mineral. However, fine grinding not only consumes a lot of electricity and raw materials, but also causes over crushing, resulting in useful minerals
