1 概述在选矿生产中,破碎和磨矿作业占有非常重要的位置,无论是基建投资、维修费用还是电耗、钢耗都占有很大的比重,特别是磨矿作业效率低、能耗高的工序。据统计,全厂生产总电耗中,破碎作业占7.2%,球磨作业占60%以上。生产实践证明,强化破碎作业、提高破碎能力、降低入
1 Overview In the beneficiation production, crushing and grinding operations occupy a very important position, whether it is investment in infrastructure, maintenance costs or electricity consumption, steel consumption accounts for a large proportion, in particular the grinding operation is inefficient, high energy consumption Process. According to statistics, the total power consumption of the whole plant, crushing operations accounted for 7.2%, ball milling operations accounted for more than 60%. Production practice has proved that to strengthen the crushing operation, improve the crushing ability and reduce the income
