PolarFit® Ultra-Fine Grinding Mill

A cost-effective way to achieve ultra-fine particles

Our PolarFit® ultra-fine grinding mill is a versatile grinding system that provides a cost-effective way to reduce hard to grind materials to smaller particle sizes than can be achieved with conventional impact mills.

It uses the power of liquid nitrogen to remove heat produced in the grinding process by controlling the temperature of your product or the mill.

The mill generates consistent yields of particles at the required mesh. In some cases, it can produce particles as small as 10 microns.

The mill is ideal for cryogenic size reduction of a wide range of materials.
