| 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. |

|
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. |

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. new type of oil filting system protects the bearings and other transmission system from accidental abrasion and prolong their servive time
- 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. main materials are from world-famous international companies, which enables VSI to continuously crush common materials for over one month without machine halt.
- 6. better design of the impellers reduces the resistance materials will meet when they pass through the impellers, and, therefore, increases passing through quantity of materials and crushing ratio. The efficiency has been raised by 30%-60% compared to traditional machines.
- 7. Hydraulic system allows automatic uncovering, reducing intensity of labour and making maintenance easier.
- 8. The mainframe is made with rivet hot technique, which enhances intensity of structure and tenacity, and ensures stable performance. The quality of the machines is lift to a higher level.
- 9. SBM-VSI crushers employ world-class light oil leakproof device, which saves the trouble of changing oil seal.
- 10. Maximum feeding size of the materials has increased to 80mm, while that of the traditonal machines is 50mm.

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. |
