Grinding machine is widely used in grinding of mineral products in metallurgy, building materials, chemical industry, mines and other fields. According to the fineness of the plastic and the fineness of the material, the grinding machine can be divided into many kinds, such as Raymond grinding, superfine grinding, trapezoidal grinding, etc.The production efficiency of the grinder directly affects the profit of the manufacturer. For the factors affecting the production efficiency of the ultrafine vertical mill, more attention must be paid to it in the production. Today, we will discuss with you what factors affect the efficiency of the ultrafine vertical mill.Material hardness is an important factor affecting the production efficiency of the grinder. The harder the material, the more difficult it is to process, and the more serious the wear of the equipment. When the hardness of the material is high, the grinding speed of the grinding machine is very slow, the grinding capacity is small and the production efficiency is low. Therefore, in the daily use of equipment, it is necessary to strictly follow the instructions of the grinder, grinding the materials with appropriate hardness.
