  • Method and device for comminuting a plastic and for producing powdered material from said plastic
    Patent number: 11534941
    Abstract: A method and device for comminuting a thermoplastic polymer, in particular a thermoplastic elastomer, and for producing therefrom pulverulent materials with a predefined grain distribution, includes the following steps: comminuting the thermoplastic polymer, which is provided in lump form, into a starting powder in a comminuting device, and subsequently screening this starting powder at least once until a predefined grain distribution has been attained. A release agent, which reduces the tack and capability for agglomeration formation of the starting powder, is fed into the comminuting device during the comminuting step.
