Product Description

Coal mill, coal ball mill used in coal mine and cement plant 

Coal Ball Mill Application:
Coal ball mill is a machine that crushes and grinds the coal briquette into pulverized coal It is important auxiliary equipment of pulverized coal furnace During the coal grinding process, the coal is crushed and its superficial area increases continually To add new superficial area, the bond between solid molecules must be overcome, so the energy is consumed The coal is grinded into pulverized coal in the coal mill mainly by means of three ways: press, strike and grind Among them, the first way is the most energy-saving, and the last one most energy-consuming During the milling process.

Working principle:
Feeding equipment sends the raw coal into louver scraper-trough conveyer of feeding apparatus. While the materials slipping down, the hot-blast air about 300ºC also enters the mill through the blast pipe and stove the raw coal. By means of the kinetic energy while slipping down, the raw coal enters the drying storehouse through the hollow shaft, and then enters the second cabin through the partition after being fully stoved. In the second cabin, there are a certain number of grinding media. Due to the rotation of cylinder, the classifying liner brings the grinding media to a certain height. Taking advantage of the impact energy and frictional energy while falling down, they crush and grind the raw coal. At the same time, the special ventilator sucks the grinded powder and the used hot-blast air out of the mill from its discharging device. The special separator separates the unqualified coarse power from the mixture of fine power and hot-blast air, and sends it back to the mill to grind again. The qualified fine powder and hot-blast air is sent into the rotoclone collector and separate here.

Structure characteristics:
The sealing elements between the feeding apparatus and rotary part, the discharging device and rotary part can prevent the powder from leaking.
The cooling water moves in the interior of main bearing to cool the bearing bush and abate its temperature.
The heat cover on the exterior of cylinder of the mill is not only heat retaining, but also is sound-proofing.
The tooth surface of the reducer is medium-hard or hard, so the reducer has good bearing capacity, long life time and light weight.
