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
Applicable material: Fly ash, lignite, coal, gangue, etc
Feeding device sends raw coals into drying oven; drying oven is equipped with special lifting plate to scatter coal and make coal get strong heat exchange so that raw coal is dried; dry raw coal is sent into grinding storehouse via double-compartment plate. Grinding storehouse is equipped with grinding balls so that raw coal can be crushed and ground into coal powder in this compartment, while, a dedicated induced draft fan carries over pulverized coal together with gas through discharging device, and coarse particles return back grinding storehouse for re-grinding.
The air-swept coal mill produced by Hongxing Machinery has reasonable structure, high grinding efficiency, strong adaptation to raw materials, which is the ideal equipment for pulverized coal preparation.
1. Reliable operation, continuous operation, high production capacity.
2. Few transmission parts, low maintenance cost.
3. The grinding body is short and thick and the length diameter is generally less than 2.
4. Big feeding hollow shaft diameter, the ventilation area between the drying bin and grinding chamber is large; the mill tail has no discharge grate, so it has small ventilation resistance.
