Two Purposes of the Crusher:

Firstly, in order to make bricks or castables with suitable particle size composition, refractory materials of different particle size levels must be prepared.

Secondly, in order to sinter bricks or castables, a certain number of fine particles must be prepared. Fine particles have enough specific surface area and specific surface energy to provide the driving force for sintering.

Crushing is a process of using external forces to overcome the cohesion of raw materials and make them produce new surfaces. Generally speaking, crushing can be divided into the following categories:

Crushing is a method of crushing raw materials by using two working faces to generate extrusion force.
Splitting is a method of breaking raw materials by wedging sharp teeth.
Fracture is the way to make the raw material bend and deform and break up.
Grinding is a kind of destructive way that uses two working faces to move relative on the surface of raw materials and exert a shear force on the surface of raw materials to make the surface of raw materials peel off.
Crushing is a way of crushing raw materials by impact force produced by the high-speed impact.
Crushing machinery often uses the above several destruction modes at the same time.
