Ore grinding medium proportioning method in one-section mill using magnetic lining plate

According to the ore grinding medium proportioning method in the first-stage mill using the magnetic lining plate, the service life of the magnetic lining plate is prolonged, and the comprehensive ore grinding index and the recovery rate index of target minerals such as lead, zinc, sulfur and silver are stably improved by using the proportioning method. According to the ore grinding medium proportioning method, the ore grinding medium is steel balls, and for the steel balls with different diameters, the proportioning scheme of initially loaded balls is as follows: phi 70mm: phi 60mm: phi 40mm: phi 30mm = 20%: 30%: 20%: 30%. According to the proportion scheme, the ratio of phi 70mm to phi 60mm to phi 40mm is 50%: 10%: 40%. 本发明提供一种使用磁性衬板的一段磨机中磨矿介质配比方法，使用该配比方法，磁性衬板寿命延长，而且综合磨矿指标和铅、锌、硫、银等目的矿物回收率指标得到稳定提高。该磨矿介质配比方法，磨矿介质为钢球，对于不同直径的钢球，初装球配比方案为：φ70mm:φ60mm:φ40mm:φ30mm＝20％:30％:20％:30％。补加球配比方案是：φ70mm:φ60mm:φ40mm＝50％:10％:40％。
