VSI crusher,VSI sand making machine

The VSI series Vertical Shaft Impact Crusher(or Sand Making Machine) is a highly efficient crushing machine with "stone to stone" crushing. The VSI crusher can crush a variety of rocks, gravel, and river pebbles into various, uniformly sized building sand with a high compression strength—greater than natural sand.

The SBM Machinery VSI crusher is designed by reputed German expert and every index of VSI crusher is in world's leading standard. SBM VSI crusher incorporates three crushing types and it can be operated 720 hours continuously. Nowadays, VSI crusher has replace hammer crusher roller crusher, roller ball mill, etc. and become the mainstream equipment in sand making business.

The VSI crusher has a optimized equipment structure. VSI Crusher is made up of First Stage Impact Curtain With Anvils, Impact Crutain Adjusting Rods, Second Stage Impact Curtain With Anvils, Rotor, Liner plate, Blow Bar, Wedge Lock Assembly, Discharge Opening, Third Stage Impact Plate, Back-up Bar and so on.

Depending on the optimized machine structure, when the equipment is working to process the mineral materials, SBM Machinery VSI crushers always use two variations of VSI crushing. The first is vertical shaft impact crushing where rock is fed onto a table type rotor which accelerates and then discharges the rock at high speed against steel anvils in the crushing chamber. The impact of the rock against the steel anvils induces fracture and breaks the rock. The second variation called vertical shaft autogenous (VSA) crushing, where rock is fed into a multi-port rotor which accelerates and then discharges the rock at high speed against a rock filled crushing chamber. The impact of rock on rock induces fracture, breaks and shapes the rock. This unique crushing action provides low wear costs, superior products and high reduction ratios.
