磨矿是选矿前的重要准备作业,磨矿效率的高低,直接影响选矿指标的好坏.通过磨矿要使目的矿物充分单体解离,同时,又要最大限度的避免金属过粉碎. 该磨矿介质的试验研究,是采用试验室型φ200×200毫米磨矿机,分别装入不同配比重量相同的钢棒和钢球,在相同试料和磨矿条件下进行的. Grinding is an important preparatory work before the dressing, the level of grinding efficiency, directly affect the beneficiation index is good or bad.By grinding to make the purpose of the full dissociation of the monomer, but also to maximize the avoidance of metal crushing Grinding medium test study is the use of laboratory-type φ200 × 200 mm mill, were loaded with different weights and the same weight of steel bars and steel balls, in the same sample and grinding conditions.
