what is the vertical roller mill

Vertical roller mill is a high-efficiency equipment that integrates fine crushing, drying, grinding, powder sorting and conveying. It can grind various materials with different strengths, hardness and moisture content. Compared with the ball mill, the energy consumption is reduced by 30%~45%, and the iron loss rate is reduced by about 60%~80%. At the same time, its advantages of large grinding particle size, high grinding efficiency, light weight and strong drying capacity are more significant. Vertical roller mills have been widely used in metallurgy, building materials and other industries as heavy equipment for grinding and grinding. plays a key role.

Vertical roller mills are mainly distinguished by different types of roller disc structures. At present, the most widely used vertical roller mill models are LM, RM, MPS, ATOX, etc. The performance of vertical roller mills is different; various types of vertical roller mills are not only different in structure and form, but also significantly different in the way of hydraulic system pressure. Generally speaking, foreign vertical roller mill technology is ahead of domestic ones.

When the vertical roller mill is running, the transmission device converts the output power of the motor into low-speed high-torque power, and at the same time supports the vertical load generated by the roller mill and the grinding disc. For the vertical roller mill, the reliability of the transmission device directly affects the normal operation of the vertical roller mill, so the reliable control and protection of the transmission device is particularly important.
