A method for reducing the size of composite material particles has a rotating cylindrical tool holder within a cylindrical stator by which the air driven particles are driven by an air vortex in the annular space

摘要

The rotor (34) of a composites reduction machine has a cylindrical construction comprising strip tools (60) on tool holders (36) in vertical stacks (40) revolving inside a stationary wall (20) and forming a narrow annular space (27) through which the composite particles are blown by an air stream to be reduced in a vortex generated in the annular space by the tool faces (62).
