高效均化库的优化设计及应用

Optimum Design and Application of High Efficient Homogenization Storage

分析认为石灰石是影响熟料生产中质量状况的主要因素。通过对目前水泥生产中原料预均化设施进行分析及比较 ,优化设计实施了以矩形均化库和配套闭路筛分破碎设施等组成的高效均化库 ,使石灰石中CaO标准偏差由进厂时的5%降至磨成的 0 8% ,石灰石粒径由原 2 5mm降至 9mm ,出磨生料三率值KH、n、p合格率分别提高 1 2 1 %、1 0 0 %、8 4 % ,熟料标号提高 ,降低了生产成本 ,年效益可达 31

Limestone is a main factor to influence quality condition in chamotte production by means of analyzing. Through analyzing and comparing to pre-homogenization e quipment of raw material in the cement production at present the high efficient homogenization storage consisted of rectangle homogenization storage and all clo sed screening and broken equipments was designed and the design has been practic ed. The standard deviation of calcium oxide in limestone is decreased from 5% to 0 8% which is from material transported into plant to finished milled ,the gra in fineness of limestone is decreased from 25mm to 9mm,the qualified rate of thr ee rate value ( KH?n?p )of milled raw material is separately increased by 12 1%,10 0%,8 4%,the grade of chamotte is increased,the production cost is decr eased and annual profit can come up to 3 1 million Yuan
