摘要
Abstract
A self-designed horizontal planetary ball mill was used to grind ground calcium carbonate.The evolution of the degree of the powder wrapping the ball versus grinding time and the effect of the powder wrapping the ball on the grinding process were studied.The results show that the ground calcuim carbonate powder wrapping the ball reaches the dynamic equilibrium in about 7 min.After powder wrapping the ball,the time to reach the grinding limit increases from 5 to 7 min,powder forming rate of less than 10 μm decreases from 72.61％ to 66.67％ while the grinding limit of the ground calcium carbonate does not change.The limit d(0.5) is between 3 and 4 μm.关键词
