How it Works: Crushers, Grinding Mills and Pulverizers
Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …

How to Process Coal into Pulverized Coal in 5 Steps?
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.

Bowl Mill Coal Pulverizer
The rate of coal feed is normally determined automatically by a combustion control system, taking into account the MW demand on the unit, coal quality, and the number of coal pulverizers in service. Centrifugal force causes the coal in the bowl to move radially outward, building up a bed of coal on the grinding ring.
