As the first stage in a crushing circuit, primary crushing reduces material to a size and shape that can be handled by a secondary crusher. Typically, the minimum setting on most primary crushers is about 4 in. to 6 in. Jaw, gyratory and impact crushers are most often appropriate as primary crushers, although there can be overlap between ...

Material breaks to fill the air pockets or voids in the crushing chamber. Impact crushing. Impact crushing is when the material is hit or thrown. This crushing process uses the theory of mass and velocity to reduce the feed material. Therefore, the faster the speed of the crusher means the finer the output.
