Vertical Shaft Impact Crushers(VSI Sand Making Machine) have maximum convertibility to handle any applications and materials. A full range of models gives customers increased tonnages, better circuit balance, and screen efficiency. The Sand Making Machine can be customer tailored to application, material condition, and desired final product size/shape.
VSI Sand Making Machine is usually used to in the manufacturing sand plant, and also as for the products shaping machine. Interchangeable crushing chambers and variable speed rotor allow for changes in material type and product specifications. Advanced double-pump oil lubrication system of Sand Making Machine guarantees shaft bearing lower temperature. Special anti-dust design for main shaft bearings of VSI Sand Making Machine can avoid dust entering bearing lubrication part, which make sure the machine work normally.
VSI crusher product advantage :
1. Deep cavity type rotor after optimization design, through material quantity increases by about 30%.
2. High sand-making ratio; good size and shape.
3. With functions of finely, coarse grinding.
4. Week guard can use back up and down after partial wear, improve material utilization, can improve the service life 48% longer.
5. Little affected by the material moisture content; water content up to 8% is available.
6. "Stone hit stone", "stone hit the iron" easy conversion; high efficiency and energy saving, high crushing ratio.
7. Cube structure, high bulk density, and small iron contamination.
8. Less wear of impeller from the lining, easy maintenance.
9. Sand Crusher Low wearing parts consumption design of the best material impact angle of crushing cavity. Less friction between wear parts, 30% lower than conventional equipment running cost.
Material from the hopper into the body, the distributor will material is divided into two parts, part from the distributor in the middle to high speed rotating impeller chamber, within the impeller was accelerated rapidly, its acceleration can be up to several hundred times the gravitational acceleration, and then at the speed of 60-70 - m/s from three uniform mass ejection of the flow passage of impeller to go out, the other part of the distributor all around, and then hit with vortex cavity lining material and be lining material rebound, oblique upward shocks to the top of the vortex chamber, and change the direction of movement, deflecting downward movement, emitted from the impeller passage of material to form a continuous material. Such a piece of material is impacted, grinded and crushed twice or more in the vortex broken cavity. The grinding materials discharge from the bottom discharging opening. In the process, materials impacting and rubbing with lining crush finely with each other without direct contact with metal components. So the iron pollution reduces and mechanical wear prolonged. Ingenious self circulation in the vortex chamber makes no powder pollution.
