Structural composition of vertical roller mill (vertical mill)

Vertical roller mill ( vertical mill) is mainly composed of separator, grinding roller device, grinding disc device, pressurizing device, reducer, motor, shell, etc. The separator is an important part to determine the fineness of the grinding product. It is composed of a speed regulating rotating device, a rotor, a guide vane, a shell, a coarse powder blanking cone, an air outlet, etc. It is an energy-saving and fast powder selection device.

The grinding roller is a component for crushing materials. It is installed on the bending arm of the mill. Under the action of external force, it is tightly pressed on the materials of the grinding plate. Driven by the grinding plate, the grinding roller rotates accordingly, so that the materials are crushed. The grinding plate is fixed on the output shaft of the reducer. The upper part of the grinding plate is the material bed. There is an annular groove on the material bed. The material is crushed by the grinding roller in the annular groove. The pressurizing device is a component that provides the grinding pressure for the grinding roll. It is composed of a high-pressure oil station, a hydraulic cylinder pull rod, an accumulator, etc. It can apply sufficient pressure to the grinding roll to crush materials. The reducer is the main part to transmit power, and the speed of the grinding plate is the speed of the reducer output shaft.
