Vertical Roller Grinding HVM Series Vertical Coal Mill For Coal Plant

Product Introduction

Coal vertical mill can be widely used in cement, electric power, steel, metallurgy and other industries, and can also process coal gangue and other kinds of coal mines. Due to its special process and structure, the coal vertical mill has less dust and noise in the production process. The pulverized coal produced has high efficiency grading and excellent combustion performance. The coal vertical mill produced by our company has simple process and compact equipment, and the fineness of pulverized coal can reach 80 μ MR 3%, with stable fineness and uniform particle size.

[Capacity]: 10~90 t/h

[Pulverized coal fineness]: R0.08=2%~12%

[Grinding disc diameter]: 1250~2800 mm

[Power of main motor]: 110~900 kw

【Working Principle】

The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is ground together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.
