BM Series VSI Crusher(VSI sand making machine) Working Principle

VSI Vertical-shaft Impact Crusher (also known as “Sand Maker”) has two feed modes – “feed at center” and “feed at center & sides”. As for the former mode “feed at center”, materials at the feed hopper firstly pass through the central hole into the high-speed spinning rotor. In the rotor, materials are fully accelerated and thrown outwards from the launching port to collide with a part of materials that freely fall after rebound. Next, materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening. As for the latter mode “feed at center & sides”, firstly, materials at the feed hopper pass through the circular hole. Then, materials are divided into two parts by the distributing tray. One part of materials enter the high-speed rotating impeller while the other part of materials fall from all sides of the tray. Materials in the impeller would be accelerated rapidly and thrown outwards at a high speed to collide with materials falling from all sides of the tray. Next, all materials hit the surrounding vortex material liner (or the impact block) inside the vortex chamber together. In the chamber, materials are bounced to the top of crushing chamber firstly and then change their direction by moving downwards to form a material curtain with materials emitted from the runner of impeller. Finally, finished products are discharged from the bottom discharge opening.

BM Series VSI Crusher(VSI sand making machine) Features

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. Overvibration alarm system.

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

6. Unique feeding method, change between central feeding and central feeding with cascade feeding makes 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.
