The Gericke Cone Mill GCN.

Cone Mill - Gericke

The Gericke Cone Mill GCN completes the range of size reduction equipment in achieving very fine particles and in increasing the bulk density.

Screen sizes range from 2mm to 150 µ.

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.

Area of application.

Cone Mills extend the Gericke range for producing fine to very fine powders (6 mm - 150 µ). Cone Mills are used for granulation processes with small particle size distribution at the end of production processes and before filling plants.

Cone Mills are well suited for recycling tasks involving the feedback of tablets, capsules and other products that require grinding to a finer particle size or whose surface area must be increased for the subsequent thermal or dispersal processes.
