Ball mill is a common and earlier grinding equipment, mainly used for grinding slag, calcium carbonate powder, cement, ceramics and other industrial waste residues.
Ball mills are widely used in the calcium carbonate industry, but in the process of using ball mills, there will be instability. It may affect the product quality and reduce the grinding efficiency of the ball mill. This article we discuss the four main factors that affect ball milling efficiency.
In the grinding process, the larger the ball diameter, the larger the impact wear and the smaller the grinding wear. The ball diameter is small, the impact wear is small, and the grinding wear is large. When the ball diameter is too large, the number of loaded grinding balls is reduced. While the grinding area of the ball mill is small, and the wear of the lining plate and the consumption of the balls will increase. If the ball diameter is too small, the buffering effect of the material will increase, and the impact grinding effect will be weakened.
If the ratio of material to water is too small, the slurry is too thin, which will lead to the direct impact of the grinding medium and increase the wear and tear of the grinding body. The spray drying process also increases evaporation. It not only wastes fuel, but also reduces the powder yield per unit time of spray drying and reduces the output.
Usually, for materials with more plastic raw materials, the value of material-water ratio is smaller. For materials with more molten raw materials, the value of the material-water ratio is larger.
Users of ball mills can effectively improve the grinding efficiency by improving the rotation rate of the ball mill, the ratio of grinding media steel balls, the material of the lining plate, and the ratio of materials to water.
