VSI Crusher Overview
VSI crusher is newly researched equipment, with international advanced level. Technology and modern processing equipment make it a leading role in this industry.
The newly-developed VSI (vertical shaft impact) crusher is designed by reputed German expert of Shibang and every index of SBM VSI crusher is in world’s leading standard. SBM VSI crusher incorporates three crushing types and changing feeding methods,so 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.Moreover vsi crusher can be operated 720 hours continuously. Nowadays, SBM VSI crusher has replaced hammer crusher, roller crusher, roller ball mill, etc.,and become the mainstream equipment in sand manking business.
VSI 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. In the fine crushing section, VSI crusher is the substitute of impact crusher, and the crusher is much better in terms of main performance indexes.
VSI Crusher Main Features and Benefits
1. Advanced double-pump oil lubrication system of the vsi crusher guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.
2. The main shaft of vsi crusher is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increase productivity.
3. Using hydraulic lifting mechanism in vsi crusher of upper cover can move away the cover easily, which saves man power during maintenance.
4. The vsi crusher is equipped with Over-vibration device. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it.
5. Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the machine work normally.
6. Vsi crusher's special feed opening structure make it possible that center feeding and ring feeding comes together, in order to meet requirements of different stones. In addition, this equipment can not only crush stone, but also iron.
7. Shape of material-thronging device of our vsi crusher is better designed, which improve the utilization ratio.
8.Optimized arrangement design of wear resistant materials increase the service life of the machine by over 40%, thus decrease the cost by over 40%.
9.The mainframe is made with rivet hot technique, which enhances intensity of structure and tenacity, and ensures stable performance.

VSI Crusher Working principle
(1) Center Feeding:
material falls down into feed hopper, then enter into impellor through entrance hole. It is accelerated in high-speed impellor, and then is thrown out at speed of 60-75m/s. When it hits impact plate, it is crushed. Final products come downwards though outlet.
Raw Materials fall into the hopper and then through the feeding opening in the center enter into the high speed rotor which will throw out the materials with high speed. Materials firstly impact those materials that are free falling down. Then, materials strike the materials-liner in the vortex or the impact liner. Due to rebound, they will back to top of crushing cavity 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.
(2) Ring Feeding:
Raw materials fall down into feed hopper, and then through ring, and is divided into two parts by material-dividing plate. One enters into impellor across the center of material-dividing plate,then is accelerated and thrown out. The other falls down from the outside of material-dividing plate. Material, which is thrown out by impellor at a speed of 60-75m/s, hits material that coming down from the outside of material-dividing plate. In this way, material is crushed.
