Wind sweeping coal mill

The wind sweeping coal mill made up of the feeding device, main shaft, rotating part, gearing, feed and discharging device, high pressure starting equipment and lubrication system is used to grind and dry coal with different hardness. Its features of reasonable structure and high grinding efficiency make it the ideal coal dust making machine which is widely applied in the industries of cement construction materials, thermal power generation, metallurgy industry and chemical engineering.

When the coal mill or coal crusher works, materials are fed by the feed device to the charging equipment of the coal mill and at the same time the hot air with the temperature of 300 degree will enter the charging device via the blast pipe. In the drying cabin there is a specially made lifting blade which can raise the raw coal to be dried with the exchange of heat. The dried materials enter the powder grinding cabin through the double layer separating board. There is a grinding body (a steel ball) installed in the cabin and the coal briquette will be crushed and ground to powder. Then the specialized induced draft fan will bring the crushed coal powder and air out from the coal mill via the discharging device and the coarse particles will return to the powder grinding cabin through the reverting spiral device for deep grinding.
