US4650126A - Process for ambient temperature grinding

Soft and tacky polymers can be ground at ambient temperature in the presence of a grinding aid in an atttrition mill having counter-rotating grinding elements operated above a minimum tip speed (170 m/sec) and at a throughput of more than about 90 kg/hr, the amount of grinding aid, which can be either organic or inorganic such as calcium carbonate, being about 5-20% based on the weight of polymer.

The grinding of porous ion exchange particles -

2016-4-1  The focus of this paper was the grinding of porous ion exchange polymer particles at ambient temperature in ball mills. The results show that it is possible to grind porous polymers in a stirred media mill down to a few hundred nanometers. This means that the model for the grinding limit according to Dugdale is not applicable for porous polymers.

Grinding - Powder Plastic Europe

2021-8-21  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. Thus, the pellets ...
