Vertical Shaft Impact (VSI) Crusher

Product Description

The vertical shaft impact crusher (VSI) is a tertiary crusher used to produce sand and chips from medium-sized hard, abrasive quarry and river material and to shape flaky material from cone crushers into cubic particles.

 

It is particularly effective on the hardest materials and has become one of the main machines for manufactured sand.

 

How It Works

Material falls from the feed hopper into the high-speed rotor and is thrown out by centrifugal force. Particles break by striking each other and the crusher wall (rock-on-rock, autogenous crushing). The crushed material discharges at the bottom, and the final size is set by the screening circuit.

 

Applications

  • Sand, chips and gravel for concrete and asphalt

  • Cubic product in limestone, basalt and dolomite quarries

  • Fine material for road construction

  • Size reduction of cement raw materials before milling

  • Bauxite, glass, industrial raw materials and manufactured sand

 

Advantages

  • Simple design, low operating cost

  • High efficiency and low energy use

  • Cubic final product

  • Low wear part cost through autogenous crushing

  • Low noise and dust, easy maintenance and installation

 

Technical Data

  • Long-life rotor, manganese steel wear liners

  • Mounts that isolate vibration from the frame

  • Hydraulic unit with electric motor and maintenance platform

  • Inverter speed control, automated feed control

  • SKF bearings in the drive
