Grinding - Powder Plastic Europe

With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).

CRYOGENIC GRINDING AND IT'S APPLICATIONS

ADVANTAGES OF CRYOGENIC GRINDING Higher material removal rate can be achieved. Tool wear and tear is minimized to a great extent. Grinding forces are reduced. Cryogens act as coolant and hence the effects of overheating of the tool and work piece are reduced. Materials which are soft and elastic in nature such as rubber can be easily machined with this process.
