The LM series ultrafine vertical mill is mainly composed of an electric motor, a reducer, a grinding roller device, a grinding disc device, a pressure device, a powder selector, etc. It is a symbol of the development of China's powder mill industry towards automated powder mills. Its emergence has made the ideal design of one-time completion of ultra-fine powder grinding, grading, and conveying operations. Its process parameters, mechanical properties, and quality of finished powder have reached international standards, comparable to those of European and American countries. In addition, the LM series ultrafine vertical grinding mill has many advantages:
1. High grinding efficiency, this machine is suitable for a variety of materials and can be variable frequency speed controlled. Its special design makes it easier to form a material layer than ordinary vertical mills and can grind the required product particle size in one go.
2. Good economic benefits, based on the principle of the first selection powder machine, and each rotor adopts variable frequency speed regulation, the fineness of the finished product can be achieved within the selected range, without the need for secondary sorting and without the presence of waste materials. The principle of ultrafine grinding and multi head powder selection can save 30% to 50% energy and economic benefits compared to other mills when producing products of the same fineness level.
3. High environmental protection level, low vibration, and low noise. The equipment is sealed as a whole and operates under negative pressure, with no dust spillage and a clean environment. The environmental protection requirements are higher than national standards.

The LM series ultrafine vertical grinding machine can be widely used for ultrafine grinding and processing of non-metallic minerals such as calcite, marble, limestone, heavy calcium, talc, barite, dolomite, etc. It is an ideal equipment for large-scale non-metallic mineral powder production.

Application scope: Calcium carbonate crushing and processing, gypsum powder processing, power plant desulfurization, non-metallic mineral powder production, coal powder preparation, etc
Materials: limestone, calcite, calcium carbonate, dolomite, barite, talc, gypsum, diabase, quartzite, bentonite, etc
