Vertical Shaft Impact Crusher

　　The Brief Introdction of VSI Sand Making Machine

　　VSI series high-efficiency vertical shaft impact crusher（VSI Sand making machine, It provides the high quality sand and crushed stone aggregate to the high-speed railroad, high-rise construction, municipal administration construction, water and electricity dam construction, concretes agitation station. It is effective machine at present. It is also applicable to crush various stones with different hardness in medium and fine crushing area. It is more advanced in intermediate hard, extra, extra hard and abrasive material crushing.

　　The Features of VSI Sand Making Machine

　　1、“stone striking stone” working principle, high efficiency, low electricity consumption, and high efficiency crushing

　　2、Strong ability of through the non-crushing material, low effects by the material moisture content

　　3、Suitable to crush stones with mid-hardness, high hardness, and super high hardness

　　4、Mechanism for the production of sand, the gradation of finished product is in an adjustable fineness modulus.

　　5、Simple structure, low cost, easy operation/ maintenance and installation

　　6、Low noise and the dust pollution

　　7、Low weight and various installation, can be installed on mobile

　　The Working principle of VSI Sand Making Machine

　　The material falls from the upper side of machine, then into the impeller, with the effect of centrifugal force, the material was crushed with other parts of the material which shunt around the impeller in a umbrella shape. After the cross impacting, the materials will be forming an eddy current and then impact, crush with each other again, then discharging from the lower part. The whole system forms a close circuit and through multi-cycles, finally matched granularity of the final product by the control of screen set.
