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 between the bowl liner …
Laboratory Roll Crusher
The 911MPELRC Laboratory Roll Crushers are typically applied in laboratory or pilot plant applications after primary reduction of the infeed material. Roll crushers operate with a minimum of dust generation and produce a material with a tight size envelope containing a minimum of fines. Designed for rapid, controlled size reduction of ore, mineral or rock prior to metallurgical …
Primary size reduction with Jaw Crushers
Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
