[0002] Mineral resources are the product of the earth's crust in its long-term formation, development and evolution. They are formed by the aggregation of natural minerals under certain geological conditions and through certain geological actions. Different geological actions can form different types of minerals. Coal mill is a machine that breaks coal blocks and grinds them into powder. It is an important auxiliary equipment for pulverized coal furnaces. The coal grinding process is the process of coal being broken and its surface increasing continuously. To increase the new surface area, the binding force between solid molecules must be overcome, so energy is consumed, mainly through crushing, crushing and grinding. There are many types of coal mills, namely low-speed, medium-speed and high-speed coal mills. Coal powder is usually used in combustion equipment such as boilers and industrial kilns. Coal mills grind the original coarse coal into fine coal powder to improve the combustion efficiency and energy utilization of coal.
