Overview Of VSI Crusher↑

SBM VSI crusher is designed by reputed German expert of Shibang and every index of VSI crusher is in world’s leading standard. SBM VSI crusher incorporates three crushing types and it can be operated 720 hours continuously. Nowadays, VSI crusher has replace hammer crusher roller crusher, roller ball mill, etc. and become the mainstream equipmentin sand manking business.

The Application Of VSI Crusher↑

VSI crushersare widely applied in expressway and railway building, hydropower station construction, highway, 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 freeze proof and leak proof. In the fine crushing section, VSI is the substitute of impact crusher, and it is much better in terms of main performance indexes.

The Features & Benefit Of VSI Crusher↑

• Advanced double pump oil lubrication system minimize the maintenance frequency
• High precision roller bearing, smooth main unit running, and long service time
• Hydraulic lift cap, easy and convenient replacement and maintenance
• Over vibration alarm system
• Special dustproof seal system, outside powder is prevented from entering oil mouth
• 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.
• Particular material throw head design and reasonable material selection prolong the service time.

Main Parts Of VSI Crusher↑

VSI Crusher is made up of First Stage Impact Curtain With Anvils, Impact Crutain Adjusting Rods, Second Stage Impact Curtain With Anvils, Rotor, Liner plate, Blow Bar, Wedge Lock Assembly, Discharge Opening, Third Stage Impact Plate, Back-up Bar and so on.

Working Principle Of VSI Crusher↑

Materials fall into the hopper and then through the feeding opening in the center enter the high speed rotor which will throw out the materials with high speed. Materials firstly strike those materials that are free falling down. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavoty 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.

Maintenance Of VSI Crusher↑

1. Checking the whirlpool cavity’s observation door whether it is closed tightly, in case the materials is fired from the observation door, to cause danger.
2. Checking the rotation direction of the impeller .The impeller should rotate in the counter clockwise, or the electro motor’s wiring should be adjusted.
3. The start sequence of the breaker and convey equipment.
4. Discharge →breaker→feed
5. Breaker muse be started up under no loading condition, the materials should be fed after the breaker is in good order.
6. The sequence of shut down and start up is opposite.
7. The feed size should be according to the requirement of every kind of machine strictly, materials over the requirements must be forbidden otherwise imbalance is produced and the impeller is wired heavily, even the tunnel of impeller and middle of feed tube will be jammed, as a result the machine can not work well.
8. Feeding should be continuous and even, The huge shake and abnormal noise shouldn’t exist in the process of the operation, or the machine should be shut down and checked.
