Impact crushers

The other type has a centrifugal crusher with vertical shaft, and it is called a vertical shaft impact crusher or VSI crusher. Horizontal shaft impact crushers . In conventional horizontal shaft impact crushers, the feed material is crushed by highly intensive impacts originating in the quick rotational movement of hammers or bars fixed to the crusher's rotor.

Rotor centrifugal crusher

The rotor centrifugal crusher is also excellent for processing slag of all kinds, thanks to its selective crushing effect. The machine separates most metal components adhering to slag without completely destroying the slag grain size. Selective crushing is also a well-proven solution for processing granulated asphalt materials.

Crusher

Impact crusher. Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.

Impact Crusher Working Principle

Impact Crusher Working Principle. Dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller. Attrition crushing is the reduction of materials by rubbing; primarily a grinding method. Shear crushing is accomplished by breaking along or across lines of cleavage.
