Feeding Granularity: Φ2.2×4.4m-Φ3.8×7.25+3.5m
Production Capacity: 8-43t/h
Application Range: Widely used in cement building materials, thermal power, metallurgical industry, chemical industry, etc
Air-Swept Coal mill is used for grinding and drying coals with high, middle and low hardness, with reasonable structure and high grinding efficiency, and it is one ideal equipment for coal powder making. Air-swept coal mill is widely used in cement and building materials, thermal power generation, metallurgy, chemical industry and other industries.
Air-Swept Coal mill is mainly composed of feeding device, main bearing, rotating part, transmission part, discharging device, high-voltage start devices and lubrication system. Air-swept coal mill uses wind-sweep-type structure with a drying storehouse, making it has greater adaptability of coal with moisture. The grinding position has combined arrange layout of ladder liner, double-ladder liner and corrugated liner, which improves the grinding ability of the coal mill. Feeding device is oblique inlet shutter-type structure which enhances thermal exchange capacity of the mill, and can effectively prevent the feeding port blocking of coal mill.
