**中文摘要:**Absrtact: Overflow ball mill is a common equipment in fine grinding of gold cyanide. There are problems of high energy consumption and ball consumption in fine grinding ball mill of Jinqiling gold mine cyanide plant in Shandong province. In order to solve this problem, the fine grinding ball mill is studied by precise ball filling technology. Firstly, the mechanical properties of the ore are tested by the rock mechanics experimental system, and the preliminary pellet scheme is calculated accurately by using the semi-theoretical formula of the diameter of the ball of Duan, and a precise supplementary pellet scheme is proposed on the basis of these. The results show that compared with the original steel ball system, the processing capacity of the mill is increased by 1,915 tons and 179 tons, and the grinding fineness is increased by 3.88% and 1.78%, respectively, by using steel ball and short cylindrical cast iron as grinding media. When cast iron is used as grinding medium, the grinding fineness index is better than that of steel ball, but the ball consumption is higher. Therefore, accurate ball filling technology can effectively reduce the energy consumption of overflow ball mill in large gold cyanide plant, and has a good promotion value.
