Overview of VSI Crusher

SBM Vertical Shaft Impact (VSI) Crusher is the most advanced impact crusher 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.

The application of VSI Crusher

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 & Benefits of VSI Crusher

1. Advanced double pump oil lubrication system minimize the maintenance frequency

2. High precision roller bearing, smooth main unit running, and long service time

3. Hydraulic lift cap, easy and convenient replacement and maintenance

4. Over vibration alarm system

5. Special dustproof seal system, outside powder is prevented from entering oil mouth

6. Unique feeding method (change between central feeding and central feeding with cascade feeding make “rock on rock” and ‘rock on iron” possible, both crushing and shaping are achieved.

7. Particular material throw head design and reasonable material selection prolong the service time.

Working principle of VSI Crusher

SBM VSI Crusher works as below: the materials enter the crusher through feeder hopper, which is divided into two parts, one part entering into the rotating through the middle of distributor impeller at high speed, then is accelerated, and shot through the tunnels around the impeller by the speed of 60-75 meter/second. First the materials will impact with some materials fallen around distributor, hit on the crushing chamber together, then will be rebounded and impact on the top of the crushing chamber, changes its direction and goes down, forms continual material layers with the materials shot from the impeller. Therefore some materials will be impacted, crushed, milled twice or more times in the crushing chamber, then crushed materials will be discharged through the bottom. This can form a closed circulation system; in general, the sand forming percentage increases 20-30% and the product shape is good. Airflow self-circulation in the crushing chamber can eliminate the dust pollution well. It is the first choice in manufacturing sand and its shape correction industries.
