VSI crusher working principle

VSI Crusher Working pinciple is as follows:

the materials enter the crusher through feeder hopper, is divided into two parts. one part go through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration. Under great centrifugal force,it is 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 classifier, then impact on the whirlpool cavity's scaleboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changs its direction and goes down, forms continual material layers with the materials shot from the impeller.

Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed matetials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system. Finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported to sand washing machine, however overlarge material will go back to sand maker to be refreshed.

Output sizes can be made according to customers requirement. If input size is larger than the designed size, other crushing equipment will be necessary. in general, materials can be crushed into 20 mesh through thrice circulation. Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
