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 …

Dynamic Analysis on Hammer of a Coal-Hammer Mill …
In a Hammer Mill crusher, the coal (app. 200 mm sizes) enters from the top and is violently thrown against the breaker blocks by the hammers. The final crushing is done between the hammer faces and the screen bars (sizes of ¼ inch or lesser). Then the crushed coal goes to the conveyors below and is carried to the storage bunkers.
