The vertical shaft impact crusher, also called sand making machine and rubble shaping machine, is a kind of crusher impacted by the materials themselves.It has the advantages of other ball mill and stone crusher in work. The stuffs, which fall into the high-speed rotating impeller from the upper of the machine, were stroked with other stuffs, which more around the impeller, because of high-speed centrifugal force.
After they strike mutually, whirling fluid is produced between the impeller and outer covering .Through repeatedly striking and rubbing, the stuffs are crushed into pieces and straightly come out of the lower. The operating process circulates repeatedly. And then attains the fineness of the product. Vertical shaft impact crusher is used for crushing highly coarse material such as aluminum oxide, ferrosilicon and other hard grinding materials. In a vertical shaft impactor, the concept of crushing is between the rocks or stones itself.
They are crushed by hitting them to the same type of materials. vertical shaft impactors are capable of crushing materials into fine and course materials.
