The grinding mill is one of the important mining machines. When grinding materials, the output of grinding mill will be affected by many factors, mainly by the particle size of the finished product, the hardness of the material, the humidity of the material, the composition of the material, the viscosity of the material, the working efficiency of the supporting measures of the equipment, etc.
