LM Vertical Roller Mill is a type of milling equipment used in various industries, including cement, metallurgy, electric power, chemical industry, and non-metallic minerals. It is designed to grind and dry materials with moisture content below 15% and hardness less than 6, such as limestone, calcite, dolomite, petroleum coke, gypsum, barite, marble, talc, coal powder, etc.
The LM Vertical Roller Mill consists of main mill, feeder, classifier, fan, air duct, hopper, and grinding roller assembly. The grinding roller assembly, suspended on the roller hanger, rotates around the vertical axis. When the motor drives the main mill through a reducer, the grinding roller rotates around its own axis and simultaneously revolves around the grinding ring. The grinding roller presses the material on the grinding ring to grind it into fine powder.
The vertical structure of the LM Vertical Roller Mill allows for efficient grinding and drying of materials. The hot air from the air ring directly contacts the ground material inside the mill, and the moisture in the material is evaporated by the hot air. This drying and grinding process helps to increase the efficiency of the grinding operation.
The LM Vertical Roller Mill provides several advantages over traditional milling equipment. It has a smaller footprint, which makes it suitable for installation in limited spaces. It offers higher grinding efficiency due to the direct contact between the grinding roller and the material. The vertical arrangement of the mill also facilitates easy maintenance and operation.
Overall, the LM Vertical Roller Mill is widely used in various industries for its high grinding efficiency, reliable operation, and ability to grind and dry different types of materials.
