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 …
The coal blocks are crushed and ground into powder in this chamber. While grinding the coal, the pulverized coal is taken out of the coal mill from the discharge device by a special induced draft fan. The coarser coal granules will return to the grinding chamber through the return screw of the discharge device for regrinding.
