Gas-flowing grinding machine with a rotating slag system, in particular knife-edge panes

摘要

The wood chip making machine has a rotating striker wheel system (cutter-crown chipper) with a striker wheel (13) and chipping tools (22,27). At least two impact surfaces (A,B,C,D) are provided, axially stepped in the depth of the chipping cavity (9). Each successive impact surface moving in the axial direction projects above the axial projection of the previous one.
