在选矿厂中,破碎和磨矿成本在选矿成本中占很大比例,而破碎产品粒度选择的合适与否直接影响到破碎、磨矿的综合成本[1],如果采用检查筛分机械还影响到破碎-筛分的循环负荷。笔者针对内蒙古包钢钢联股份有限公司巴润矿业分公司(以下简称巴润矿业分公司)在生产过程中,破碎产品粒度合格率与破碎-筛分的循环负荷所产生的矛盾关系[2],进行了分析与考察,以求获得最佳的解决办法。
In the concentrator, the cost of crushing and grinding accounts for a large proportion of the cost of dressing, and the appropriate choice of the size of the crushed products directly affects the comprehensive cost of crushing and grinding [1]. If the screening and screening machinery is also used, To crushing - sieving cycle load. The author of Inner Mongolia Baotou Steel Co., Ltd. Barun Mining Branch (hereinafter referred to as Barun Mining Branch) in the production process, the broken rate of the product size and crushing - sieving the cycle of the load generated by the contradiction [2] , Carried out analysis and inspection, in order to obtain the best solution.
