A ball mill is a grinding machine, a cylindrical device used to grind (or mix) materials such as ores, chemicals, ceramic raw materials, and paints.
During the use of ball mill, the selection of grinding media is crucial. Grinding media is affected by many factors such as material, loading, shape, particle size, etc. In the process of grinding, different grinding media are used for different materials, models, and equipment, which can reduce production costs and improve production efficiency.
The greater the density of the grinding media, the shorter the grinding time. In order to increase the grinding effect, the hardness of the grinding media must be greater than the hardness of the material being ground. According to long-term experience, the Mohs hardness of the medium is preferably 3 levels greater than the hardness of the material being ground. In addition, the smaller the size of the grinding media, the more contact points there are, and the more opportunities there are to grind the material.
The grinding material determines the cost and efficiency of the crushing. Grinding materials can be mainly divided into three categories: metal media, rock and mineral materials, and non-metallic materials. In addition to considering production costs, we must also consider whether the materials and media will cause pollution.
Grinding media are generally spherical, because other irregularly shaped media will wear themselves and cause unnecessary pollution. The size of the medium directly affects the grinding efficiency and product fineness. The larger the diameter, the larger the product particle size and the higher the output; conversely, the smaller the medium particle size, the smaller the product particle size and the lower the output. In actual production, it generally depends on the feed particle size and the required product fineness.
