Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in largescale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.
Hammermills can be used as a primary crusher in many types of aggregate and industrial applications, including limestone, marble, shale, gypsum, phosphate, bauxite, aluminum dross, uranium, cryolite, clinkers, quicklime, petroleum coke, coal and more. Using a combination of impact, shear and attrition reduction methods, Hammermills tend to ...
Secondary crushers Cone crusher Roll crusher is done to reduce the ore size suitable for ( wet ) grinding. The feed size will be less than 150 mm avg. dia product size 12 mm The crushing machine does not have wider GAPE and very sturdy construction. Secondary crushers are arranged in series with the primary crushers.
The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.

Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
Solutions has in its range two types of jaw crusher, which differ in the kinematics of the swing jaw: singletoggle jaw crushers for a high throughput rate and double • toggle jaw crushers for extremely hard materials and abrasive rock.
