WORKING PRINCIPLE. The motor drives thegrindingtable through decelerator. The materials fall down the center ofgrindingtable from feed opening. At the same time, hot air comes into themillfrom the air inlet. Due to the centrifugal force, materials move to the edge of thegrindingtable.
In a vertical roller mill,materials to be ground fall upon the center of a rotating grinding table. Centrifugal force causes the materials to spread out evenly towards the edge of the plate. Asparticles lying flatly on the plate reach a certain thickness, they areground or crushed by multiple pairs of rollers.

The working principle of the vertical coal grinding mill is similar to that of vertical raw mill. Grinding mill motor start: The start working of vertical coal mill is driven by an electric motor. The raw coal enters the vertical mill bin: The reducer drives the millstone to rotate, and the raw coal enters into the mill through the feed port, scattering on the millstone.
Vertical raw mill is important equipment widely used in the cement raw meal (cement raw materials) grinding section of the cement production process in cement plant. Because the vertical raw mill is the use of roller grinding principle to crush materials, its vertical raw mill operation is more efficient and energy-saving, product output is more stable, so in cement industry, electric power, metallurgy, …
