    • Mill Grinding Of Polymers

    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.

    • Fine grinding of polymers in a vibrated bead mill ...

    1999-11-1  A study has been presented on ambient and cryogenic dry grinding of various polymers in a vibratory bead mill: PVA, the particles of which are agglomerated, and PS and PE which are compact particles. It has been noted that the necessity of using cryogenic conditions is linked to the glass temperature of the materials.
