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…
