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.

There are countless polymers that due to their low density and melting points, grinding with mills at a room temperature is not possible because the friction of the mill itself generates a temperature higher than the melting point of the polymer and therefore the polymer liquefy. With cryogenic grinding we solve this problem.

Grinding spices: How does cryogenic grinding work? Mill cooling uses liquefied cryogenic nitrogen (LIN) or liquid carbon dioxide (LCO2) to significantly reduce the temperatures of the feed material. Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle.

The cryogenic size reduction process, also known as "cryomilling", involves exposing the resin pellets to temperatures of -100° Centigrade or lower. These temperatures lead to finer grains, as they make even the most elastic polymers more brittle. This environment also suppresses recovery and recrystallization.
