After crushing, small pieces of coal enter into the coal mill for grinding. Usually a complete coal milling line includes coal mill, impulse dust cleaner, piping device, cyclone collector device, classifier. The stones are squeezed by roller and ring into powder, the powder is collected by cyclone collector.

When the coal, still wet from cleaning, was first charged into the oven, it would begin to steam. Next, the coke worker would put the damper on at the top, and seal the oven almost all the way up with bricks and mud. Gradually, the escaping smoke would turn blue, then to a thick yellow. About an hour later, the man knew the coal was ready to ...

Bowl mills are used for pulverizing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.
