Industrial Test on Application of Ceramic Ball in a Zinc-tin-copper-iron-sulfur Polymetallic Ore
In order to improve the beneficiation technical index of a zinc-tin-copper-iron-sulfur polymetallic ore in Yunnan and promote the development of green and low-carbon,aiming at the problems of high energy consumption in the steel forging grinding process and easy overgrinding of grinding products,the industrial application of two-stage grinding with nano-composite ceramic balls replacing steel forging was studied.The results show that the grinding of nano-composite ceramic balls can improve the particle size distribution characteristics of grinding products,and the content of easy-to-select particles increases signif-icantly.The yield ofultra-fine grain size-0.010 mm in the overflow product is reduced by 1.30 percentage points,which effectively reduces the over-grinding and increases the theoretical recovery rate of tin rough concentrate by 0.60 percentage points.The unit power consumption of grinding is reduced by 43.32%,the unit ball consumption is reduced by 10.34%,and the comprehensive grinding cost is reduced by 31.00%.The effect of energy saving and consumption reducing is remarkable.
