Vertical roller mill is a kind of "ring-roller" mill combined with air flow screening, pneumatic conveying form of pulverizing equipment. It has the characteristics of continuous pulverizing, the concentration of powder particle size distribution, continuously adjustable fineness, compact structure and so on.

Its grinding mechanism is suspended roller and fixed ring grinding disc, so it is also called suspended roller grinding machine. Three to five grinding rollers suspended on the plum blossom rack at the end of the rotating spindle swing outward under the action of centrifugal force.

Material is crushed between the grinding rollers and the annular grinding disc. SBM Mining Machinery Co., Ltd. specializes in the development of grinding equipment. It has many years of history. The Vertical roller mill produced by SBM Mining Machinery Co., Ltd. is suitable for grinding materials below medium hardness, such as coal, petroleum coke, smelting coke, needle coke, silicon carbide, etc.
