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 ?6mm 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.
