Abstract
A rotor assembly operable with anvil mechanism for comminuting waste wood and other fragmentable material has a rotating drive shaft with a series of rotors fixed in axially spaced relation thereon. A series of radially projecting hammers mechanisms are situated along the axis of the shaft and powered by the shaft. Fragmenting knives are removably secured to the leading outer portions of the hammer mechanisms. The hammer mechanisms include sidewisely reversible hammer legs having portions received by the rotors sidewisely contiguously.
Claims6
In a method of making a fragmenting rotor assembly operable with anvil surface for comminuting waste wood and other fragmentable material:
- a. providing a drive shaft and mechanism for driving said shaft in a direction of rotation;
- b. providing a series of radially projecting side for side reversible hammer supports with radially outer hammer heads situated along the axis of said shaft and powered by said shaft, the hammer heads having a leading portion and a trailing portion;
- c. providing fragmenting knives with axially extending reducing edges removably secured to the rotatively leading portions of said hammer heads;
- and
- d. mounting separately replaceable deflecting members independently of said hammer heads and radially between each pair of hammer heads which have outer ends moving in a circumferential path of lesser radial extent than the circumferential path of said knife edges.
