VSI crusher

Operating Principle:

The material is feed into crusher though a feed hopper.There is a feed choke plate to control the volume into motor.This choke plate is control by hydraulic system and easy to use.The material falls down to feed tube by gravity action and continuously falls into rotor.The rotor is driven by a belt pulley which is connected with electrical motor. When the material enters into rotor, it is speeded up to 45-65m/s by function of centrifugal force.Then the material will fly out from rotor through designed moving path.The ejected material will hit the material piled inside crusher cavity,and violent crash will happen. This high speed ¡®Rock to Rock¡¯ crash causes impact, cleavage and attrition of the feed material.


Main components: 

 

Advantages:

1.Large throughout, high output

The structure of SK VSI series crusher is more compact after optimization design;

Due to adopting signal drive shaft, the power is stronger. Therefore, it can obtain higher reduction ratio with fewer crushing stages.

2.Low consumption of wear parts

SK VSI crushers adopt optimal design of crushing cavity,reducing friction of wear parts.So it can reduce operating cost by 30% compared with traditional equipment.

3.Excellent particle shape

The final products¡¯ shape of VSI crushers are cube and excellent. The machine is especially suit to make artificial sand and reshape stone materials. The practice proves that its efficiency increase by 30% compared with others traditional equipment.

4.Flexible and wide application

The strength of VSI crushers make them ideal for every kind of application in many different configurations.VSI crushers have demonstrated their effectiveness in many applications from crushing low abrasion materials to extremely abrasive products for industry.

5.Integrated hydraulic control and bearing lubrication

The hydraulic console is standard configuration. It has a dual function.The one function is to control throttle gate that controls the feed rate to the rotor.The other is to manage hydraulic adjustment of the motor mount.All these adjustment are completed by a simple one-person operation.The semi-automatic metered grease system is completely sealed to prevent ingress of dirt and dust with perfect lubrication effect.

6.Unique chamber geometry

Extremely modular, VSI crushers layouts can in the same frame, be changed without major modifications from rock-to-rock chamber to rock-to-iron chamber.They feature many technical benefits such as the tapered shape of the anvil making it possible to turn them when they are half worn and to boost the payload, thereby improving productivity. The specific shape of the closed rotor reduces rotor wear and maintenance costs by increasing reduction factors.

7.Easy to maintain with high security level

VSI crusher frame is open/closed by a jack.The interior of the crusher is accessed via safety doors behind the lid.Particular care has been taken to secure and simplify plant maintenance.A central lubrication system optimizes bearing greasing and reduces the number of servicing interventions.
