Impact Crusher

Impact Crusher is the kind of rock crusher.A rock crusher is a machine designed to take large rocks as and reduce them to smaller rocks, gravel, or rock dust. Rock crushers produce aggregates and ready-to-process mining ores, as well as rock fill material for landscaping and erosion control.

There are two types of impact crushers. The Horizontal Shaft Impact Crusher (HSI Crusher) and the Vertical Shaft Impact Crusher (VSI Crusher). The HSI crushers break rock by impacting the rock with hammers that swing on a rotating shaft. The practical use of HSI crushers is limited to soft materials and non abrasive materials, such as limestone, phosphate, gypsum, weathered shales. HSI crushers achieve the highest degree of reduction. The VSI crushers can also break rock by impacting the material with rotating hammers, traditionally this is referred to as a "Shoe and Anvil VSI" and has similar limitations to the HSI crusher.

The VSI crusher uses a different method involving a rotor with wear resistant tips and a crushing chamber designed to retain a protective layer of crushed rock for new rock to be crushed against - "rock on rock". Using this method materials with much higher abrasiveness can be crushed.

Working principle:

Our impact crusher uses plate hammer on the rapidly rotating rotor to generate high-speed impact to crush the materials in the crushing cavity, and casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity. The materials are crushed again, and then, they return to the plate hammer to undergo the process above repeatedly.

The materials are bumping with each other when being sent between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged

Performance features:

Our impact crusher is with unique structure, keyless connection, high-chromium plating hammer and special impact liner plate; it is capable of highly efficient hard rock crushing while saving energy; the product is in the shape of a cube, the discharge grain size is adjustable to simplify the crushing circuit.
