What Is a Vertical Roller Mill?

Vertical roller mill is referred to as vertical mill for short. It is used for the grinding of cement raw material, cement clinker, slag and cinder. It has the characteristics of simple structure and low manufacturing and use costs. It includes a body, a grinding disc device and a transmission device. A centering structure for determining the center of rotation is provided between the body and the grinding disc device. A rotary guide is fixed at the bottom of the grinding device. Transmission transmission connection. Because the transmission device does not bear high axial loads such as the weight of the grinding disc and the grinding pressure, the transmission device can use a universal reducer, which has the advantages of compact structure and reliable operation, which can shorten the downtime and reduce the use and maintenance of equipment cost.

The influence of the curvature of the grinding disc and roller on the grinding capacity and the unit power consumption was mainly studied to determine the optimal grinding curvature. Perform structural analysis and calculation of static and dynamic loads on large parts such as the grinding disc base and pressure frame, optimize the determination of the cross-sectional dimensions of the pressure frame, and find out the optimal shape of the stress distribution on the grinding disc base, which is good for the casting process. The effects of thermal stress are fully considered. Based on the research and analysis, we developed and designed an efficient combined powder separator suitable for the MLS3626 vertical mill. It is important to consider the control of the powder selection area and the movement of the particles, to limit the amount of irregular movement in the mill as much as possible, reduce the cycle load from the surface, and improve the grinding efficiency.

Vertical mills are based on humidification towers and

1. The above data is the reference duty for processing brittle materials with Mohs hardness less than 7.

2. When the moisture content of the finished product is less than the moisture content of the raw materials, the hot air is allowed to pass through.
