Vertical coal mill is typically designed to process materials in medium hardness, like soft coal or bituminous coal, and it is mainly used in positive pressure pulverizing system of soft coal.
Coal vertical mill working principle
After Rotary feeder coal vertical mill feed, with the rotation of the disc from the center to the edge of the motion, while roller by squeezing grinding. After grinding disc at the edge of the pulverized coal to be brought up from the hot gases into the air ring, the meal back to the disc and then grinding, qualified powder into the hot air from the bag filter after collection by the screw conveyor to the side of the library hoist into finished products. Drying heat generated from the combustion hot stove in the scene. Hot air through a pipe into the mill, the vertical mill after the gas cleaning system by the fan into the chimney, where a portion of the cycle again into the mill through the circulation duct.
