Overview of Vertical Shaft Impact Crusher
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.
Vertical Shaft Impact 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.
Application of Vertical Shaft Impact Crusher
Vertical Shaft Impact Crusher is widely applied in expressway and railway building, hydropower station construction, bridge and tunnel building, concrete batching plant, etc for crushing and gravel shaping.It is 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. 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.
