Ceramic Ball Mill Machinery Ceramic ball mill, as a necessary machinery in the ore dressing process, is mainly used for mixing and grinding materials such as fluorite, glass ceramics, ferrous metals, nonferrous metals and so on. It excels in processing materials with strict requirements for purity and iron content.The length of the grinding time can control the particle size of the material, i.e. the longer the grinding time, the finer the particle size of the material.
