1. Accurately control the amount of material used.
2. It has the function of fine grinding and coarse grinding.
3. Easy maintenance.
4. High crushing rate and energy saving.

When the materials fall into the feed hopper, through the center hole they enter the high-speed rotation of the rotor then were full speed and thrown out through the emission mouth.

First hit the rebound after free fall impact part of the material, then hit together around the whirlpool of vortex chamber of on line (or back), bounced into the crushing chamber at the top of the first, then deflect downwards, then hit the material that emitted from the impeller passage to form a continuous material curtain, finally discharge through the lower part.
