磨球是选矿生产的大宗消耗材料,其成本,占铜选矿20—30%,占铅锌选矿10—20%。磨球质量的好坏和消耗的高低,关系到企业的经济效益。据对50个铜铅锌矿山统计,平均磨球单耗1.76公斤/吨矿石,高于国外1—2倍,全国统配有色矿山每年大约消耗磨球10万吨。因此,无论从企业升级,贯彻“双增双节”方针,还是从提高企业经济效益来考虑,都要求我们必须采取一切有效措施,在短时间内把有色矿山磨球消耗降下来。有色矿山磨球消耗高,有质量上的问题,有使用方面的问题,也有管理的问题。就质量问题而言,近几年由于钢铁材料紧俏,供需不平衡,矿山为了维持生产,不得不多渠道进货,难免鱼目混珠,质量大幅
Ball grinding is the bulk of consumption of mineral processing materials, the cost of copper accounted for 20-30%, accounting for 10-20% of lead and zinc beneficiation. The quality of ball grinding and the level of consumption, related to the economic efficiency of enterprises. According to the statistics of 50 copper, lead, and zinc mines, the average grinding ball unit consumption of 1.76 kg / ton ore, 1-2 times higher than abroad, the country’s total distribution of colored mines consume about 100,000 tons of grinding balls each year. Therefore, both from the enterprise upgrade, implement the “double increase double” policy, or from improving economic efficiency to consider, require us to take all effective measures to reduce the consumption of non-ferrous mining ball down in a short time. Non-ferrous mining ball consumption is high, there are quality problems, the use of the problem, there are management issues. In terms of quality, due to the shortage of steel materials and the imbalance between supply and demand in recent years, the mines have to purchase many channels in order to maintain their production.
