How to Process Coal into Pulverized Coal in 5 Steps?
With a ball mill . 1 To pulverize crushed coals in a ball mill, you start by feeding the mill with crushed coal. Then the grinding media crushes and grinds the coal in the rotating chamber. 2 Airflow carries the pulverized coal out of the ball mill. 3 Next, you'll need to use the mill classifier to separate the fine coal particles from the airflow.

Coal Pulverizers
Coal mills or pulverizers play a very essential part in the coal-fired power production system. Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. Mills can be a bottleneck for the power generation process.
