ABSTRACT:
In an apparatus and method for comminuting solid material a plurality of comminuting rollers are journalled for rotational motion in a generally circular arrangement to form a tubular enclosure. Solid pieces of material introduced into the enclosure are driven orbitally at a speed sufficient to be forced centrifugally outwardly against the comminuting rollers. Puncturing elements on the rotating rollers operate to comminute the pieces of material by a rolling, puncturing action. In a preferred embodiment, the rollers are powered and are rotated conjointly to engage and drive the solid material orbitally. Additionally, an impeller may be employed to drive the material within the enclosure, and in yet another embodiment, the entire enclosure, including the rollers, is rotated.
