2.2×4.4m & 2.2×5.8m Ore Grinding Mill Wind Air Swept Coal Mill For Mining

Air Swept Coal Mill Wind-Swept Coal Mill OF Ore Grinding Mill

1. Working principle of wind-swept coal grinding of ore grinding mill

The raw coal is fed into the drying bin of the mill by the slip of the feeding device. The hot air with the temperature of about 350℃ also enters the mill through the air inlet pipe to dry the raw coal. After drying, the coal enters the grinding bin through the bin board and is crushed under the impact and grinding of the grinding body (steel ball). At the same time, the gas formed by the special exhaust fan takes the pulverized coal out of the mill through the discharging device.
