Cement Vertical Mill

Grinding roller is the main components for materials rolling and grinding. Cement Vertical Mill is equipped with two pairs of grinding roller, each pair of grinding rollers mounted on the same axis with different rotating speed. Disc of grinder is fixed in the output shaft of reducer and upper part of the disc is the material bed which has annular groove. PRM-type vertical mill is composed of the separator, roller disc, compression device, reducer, motor, shell and other parts. The separator is an important component to decide fineness and it is made up of adjustable speed gear, rotor and guide blades, shell, meals off the material cone hopper, the outlet. The working principle is similar to powder concentrator machine. Pressure device is to support the components so called grinding pressure and the composition mainly contains the high-pressure filling stations, hydraulic cylinder, lever and storage, etc., exert enough pressure to make the material grinding to the grinding rollers.
