Abstract

A device is described for fine grinding of plastics in which the horizontally mill is charged with the plastic to be ground and with liquid nitrogen for making the plastic brittle. The grinding chamber contains an assembly of loose grinding rods. The rods are somewhat shorter than the length of the grinding chamber, whereby during the operation of the mill at least a few of the rods will strike against the end walls of the grinding chamber and transfer to these end walls, which are grounded, the electrostatic charges formed on the surface of the particles of the ground plastic and which by said rods are conducted to said end walls and from there to the ground.
