Primary & Secondary Sizers
Primary and Secondary Sizers are sized and selected based on the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency. Sizers use an electric motor to drive the gear reducer, which is mounted directly to the crushing shaft.
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 …
