Principle of operation.

The Cone Mill incorporates a vertically mounted rotating tool which moves the material across a conical static serrated screen introducing a low velocity high impact cutting action into the product which is fed by gravity into the machine.

Sub screen size product passes through the screen into the chamber whilst oversize particles not reduced by the first pass are carried by the vortex action of the tooling up towards the inlet returning it into the cutting chamber until the desired particle size distribution is achieved.
