Difference between revisions of "Vertical Shaft Impact Crushers"

'''Vertical Shaft Impact''' crushers use a different approach involving a high speed rotor  with wear resistant tips and a crushing chamber designed to 'throw' the  rock against. The VSI crushers utilize velocity  rather than surface force as the predominant force to break rock. In  its natural state, rock has a jagged and uneven surface. Applying  surface force (pressure) results in unpredictable and typically non-cubicle resulting particles. Utilizing velocity  rather than surface force allows the breaking force to be applied  evenly both across the surface of the rock as well as through the mass  of the rock. Rock, regardless of size, has natural fissures  (faults) throughout its structure. As rock is 'thrown' by a VSI Rotor  against a solid anvil, it fractures and breaks along these fissures. Final particle size can be controlled by  

*the velocity  at which the rock is thrown against the anvil and
