VSI Crusher Machine

VSI Crusher Machine Overview

VSI(vertical shaft impact) crusher machine 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 crusher machine is designed by reputed German expert of SBM and every index of SBM VSI crusher machine is in world’s leading standard. SBM VSI crusher machine incorporates three crushing types and changing feeding methods, so can be used as a crusher machine or a shaper. So, customers do not need to expand investment, they have a crusher machine and a shaper at a time. Moreover VSI crusher machine can be operated 720 hours continuously. Nowadays, SBM VSI crusher machine has replaced hammer crusher machine, roller crusher machine, roller ball mill, etc. and become the mainstream equipment in sand making business.

Our VSI Crusher Machine is the most advanced impact crusher machine in modern world. It introduces high quality roller bearing like Sweden SKF and America TIMKEN, which ensure the smooth running of main unit. Hydraulic system used in upper cap, it is easy and convenient to maintenance and replace spare parts. The feeding is our sole patent that using central feeding and central feeding with cascade feeding, the feeding method can change as per needed so as to satisfy customer’s different request.

VSI Crusher Machine Application

VSI crusher machines 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 machine is the substitute of impact crusher machine, and it is much better in terms of main performance indexes.

VSI Crusher Machine Main Features and Benefits

• VSI crusher machine advanced double-pump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation.
• Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increase productivity.
• Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.
• Over-vibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the crushering machine, in order to protect it.
• Special dust-proof design for main shaft bearing fully avoid dust entering bearing lubrication part, which make sure the crushering machine work normally.
• Special feed opening structure make this crushering machine possible that center feeding and ring feeding comes together, in order to meet requirements of different stones. In addition, this crushering machine can not only crush stone, but also iron.
• Shape of material-thronging device of this crushering machine is better designed, which improve the utilization ratio.
• Optimized arrangement design of wear resistant materials increase the service life of the crushering machine by over 40%, thus decrease the cost by over 40%.
• The mainframe of VSI crusher machine is made with rivet hot technique, which enhances intensity of structure and tenacity, and ensures stable performance.

VSI Crusher Machine Working Principle

(1) Center Feeding:
Raw material falls down into feed hopper, then enter into impellor through central 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.
