air classifier

The grinding action is created by a variable speed stirrer which agitates the grinding media. The feed particles pass through the media bed entrained in the airstream and exit into an air classifier where the on size particles are removed and the oversize particles returned to the fine grinding mill.

Pin Mills

To vary the tight range of particle sizes desired, the operator simply adjusts the speed at which the inner disc rotates, from several hundred to more than 5000 RPM depending on mill diameter. This extreme flexibility enables a MUNSON Pin Mill, with no modifications, to grind friable materials into tight size ranges from coarse particles

Pigment Grind: How to Efficiently Adjust the Fineness

In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.
