Chaeng(Great Wall Machinery) pulverized coal grinding system specifications can be divided into: GRMC17.21 coal vertical mill, GRMC19.21 coal vertical mill, GRMC24.31 coal vertical mill, its production capacity is designed to be divided into: 20t / h, 25t / h, 40t / h to meet a variety of applications on the market in the field of coal-fired boilers, and the pulverized vertical coal mill is the world's leading coal preparation facilities have been highly rated domestic and foreign customers.

First, what is coal vertical mill production process is the full set of equipment?

                   Figure: coal vertical mill process flow

Second, what's working principle of coal vertical mill ?

coal feed the vertical mill After Rotary feeder , with the rotation of the disc from the center to the edge of the movement, at the same time by the coal vertical grinding mill roll extrusion and 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 collecting chute transported by air to the library side of the elevator into the finished products. Drying heat generated from the combustion hot stove in the scene. Hot air through a pipe into the mill, the 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.

Third, What's the technology advantages of coal vertical mill?

1, set the grinding, drying, separator, delivery in one energy efficient.

2, disc shape is conducive to the material after grinding the edge of the disc was promptly thrown into the isolated, reducing over-grinding. High efficiency, low power consumption.

3, coal vertical mill roll grinding machine pulls out, the repair and replacement of wearing parts is very convenient.

4, the roller sleeve symmetrical shape of the tire structure, can be used upside down, long life, low operating costs.

5, the separator for the efficient dynamic - static separator, high efficiency, small resistance.

6, with a limit device can be prevented when no material on the disc and roller disc in direct contact, wear and avoid severe vibration.
