ABSTRACT:
A comminuting chamber (24) and attachments therefor for comminuting solid material into a particulate form is disclosed. The chamber includes a rotatable sidewall (40), a bottom (41) disposed across an end of the sidewall, and a toothed disk (32) rotatably mounted within the chamber adjacent the bottom. At least one attachment (28) is secured to the bottom of the chamber and provides a variety of surfaces which engage and reorient material being comminuted in the chamber. The attachment may include a plate (30) that extends horizontally in a plane adjacent the bottom. An edge of the plate may further have a flange (80) that extends outward and downward toward the chamber bottom. The attachment may also include a rotary scrubber (38) having a hub (56) and a plurality of arms (58) extending radially outward from the hub. The scrubber is either rotatably mounted on the plate or on the chamber bottom. Where the attachment includes a plate, riser plate members (88) extending upward into the chamber may be attached to the plate. The plate may also include upward-extending scraper plates (92) adjacent the comminuting chamber sidewall for scraping material that has collected on the chamber sidewall as the sidewall rotates. By engaging and reorienting the material being comminuted in the chamber, the attachment surfaces improve the efficiency of the comminuter.
