ABSTRACT:
An apparatus for grinding and mulching landscape debris includes a plurality of cylindrical chambers of different sizes. A first intake chamber has an opening through which the landscape debris is inducted into the apparatus. A second, larger diameter cutting chamber is connected to and is concentric with the intake chamber. A plurality of cutting blades chop the landscape debris which is present in the cutting chamber. A third, still larger hammer chamber is connected to and is concentric with said cutting chamber. The hammer chamber includes a plurality of free-swinging hammers which grind the landscape debris to a size which can exit through a perforated grinding ring which surrounds the hammer chamber. A blower chamber surrounds the perforated grinding ring, the blower chamber including a plurality of rotating fan blades which force air out of an exit opening in the blower chamber, thus creating a partial vacuum in the hammer chamber. The increasing sizes of the intake, cutting, and hammer chambers assure that the average dwell time of debris particles per unit length of chamber decreases as the debris particles proceed from the intake chamber to the cutting chamber and then to the hammer chamber.
