Abstract：In order to explore the cement grinding characteristics of high-energy vibrating mill,the semi-finished cement with a specific surface area of 1 850cm2/g was used as the raw material.The control parameters such as grinding time,mass ratio of cement-to-ball,specification and filling rate of the ball mill on the specific surface area of products and power consumption of vibration were studied.The results show that the high-energy vibrating mill has a good grinding grind ability,the grinding efficiency decreased with the increasing of grinding time,and there is a good linear relationship between the logarithm of cement specific surface area and grinding time.While taking into account the grinding efficiency and production capacity,there is a suitable key parameter intervals existing for both mass ratio of cement-to-ball and filling rate.The miniaturization of the ball mill size can improve the fine grinding capacity.Under the experimental conditions of 8%mass ratio of cement-to-ball,80%filling rate with the ϕ6mm steel ball,the specific surface area of product can reach 3 486cm2/g after grinding for 5min.The grinding power consumption is 17.9kW·h/t.
