The working principle of VSI Crusher (sand making machine) has mainly stone hit the stone (material against material) andstone hit iron (material against iron).
Stone hit the stone (material against material): through the hopper, the material enters into the crusher, and is divided into two parts by bulk cone. A portion of materials falls into the high-speed rotation swing wheel, and is rapidly accelerated. Then it is thrown away from the swinging wheel. This parts material hit another part material, which falls down from all round of the bulk cone.
Stone hit iron (material against iron): The basic work principle is similar with “stone hit the stone”. The difference is that the crushing cavity of "stone hit stone" installs the impact board, and the material forms material lining. But “stone hit iron” use the around guard plate replaced the lower guard board, and the material directly impact on the around guard plate and broken.
Reliable dual pump oil supply lubrication system—stable performance, long life;
Hydraulic pressure jack device—convenient, timesaving and laborsaving for maintenance;
Installation mode selection—handy installation, diversified modes, easy to operate;
Crushing principle selection—impact grinding with superior particle shape;
Chamber type optimization design——lessening consumption of wearing parts;
VSI series crushers are widely used in crushing nonmetal mine, concrete, fireproof material, abrasive filler, frit, construction aggregate, sand, metallurgy and so on.
It is the indispensable machine in sand making industry and it is also the most ideal truing machine for mining and construction industries.
