Grinding - Powder Plastic Europe

2022-1-1 · 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.
