Cryogenic grinding is necessary for materials with a low melting point or those that are very tough and difficult to grind fine without extra cooling. Fine grinding/pulverization/cryogenic grinding is available for 8 - 200 mesh or 2000 - 75 microns and finer for friable materials. Quote and Buy Save Select Component Supply

Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

Advantages of Cryo Grinding - AAAmachine

Ultra-fine Particle Grinding. OGL's cryo grinding process produces much more finely ground particles than conventional milling methods. OGL cryo mills are able to grind many materials to 10µm average particle size or smaller. This improves the particle flow of polymers and dispersion potential for processed polymers and foodstuffs in liquid.
