ABSTRACT:
In cutter-drum apparatus wherein a cutter drum is provided near the back of the cut with a nozzle holder and nozzles for comminuting without dust evolution of the harder material at the back of the cut, improvements whereby (a) the nozzle holder is frusto-conical to accommodate the bulging of the face at the back of the cut, and (b) the cutter drum has a frusto-conical end ring which bears cutter picks that intersect the jets emerging from the nozzles. These cutter picks give the jets a pulsating action, which increases their effectiveness.
