Vertical Shaft Impact Crusher Overview

The newly- developed VSI (vertical shaft impact) crusher is a crusher and shaper. Changing feeding methods and core structure of the crushing cavity, it can be used as a crusher or a shaper. Thus, customers do not need to expand investment, they have a crusher and a shaper at a time.
    SBM VSI crusher is designed by reputed German expert of Shibang 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 equipmentin sand manking business.

Vertical Shaft Impact Crusher Application

VSI crushers are widely applied in expressway and railway building, hydropower station construction, bridge and tunnel building, concrete batching plant, etc for crushing and gravel shaping.They are highly recommended when it comes to the shaping of gravels used in concrete aggregates, whose concrete strength is above C 60 or which required to be freezeproof and leakproof. In the fine crushing section, VSI is the substitute of impact crusher, and it is much better in terms of main performance indexes.

Vertical Shaft Impact Crusher Main Features and Benefits

1. Special light oil lubracation system ensures the temperature to be below 25℃.
    2. Brand new automatic protection device supplys VSI with vibrating, oil filtering and warning systems.
    3. Hydraulic system allows automatic uncovering, reducing intensity of labour and making maintenance easier.
    4. Optimized arrangement design of wear resistant materials increase the service life of the machine by over 40%, thus decrease the cost by over 40%.
    5. The mainframe is made with rivet hot technique, which enhances intensity of structure and tenacity, and ensures stable performance.
Vertical Shaft Impact Crusher Working Principle
Feed at center
    Materials fall into the hopper and then through the feeding opening in the center enter the high speed rotor which will throw out the materials with high speed. Materials firstly strike those materials that are free falling down. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavoty and then fall down. After that, the falling materials with materials shot from the impeller form a continuous materials curtain. Ultimately, crushed materials will be charged from the discharging opening.
    Feed both in the center and from sides
    The materials fall into the hopper and circle hole and then will be divided into two parts by the distributing plate. One part of materials cross the distributing plate and enter the high speed impeller and then is accelerated and thrown out .The other part falls down from the sides of distributor. Materials firstly strike the free falling down materials. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then fall down. The falling materials with materials shot from the impeller form a continuous curtain of materials. At last, crushed materials will be discharged from the discharging opening.
