Model SBB-12, a spiral-bottom round-bowl unit with a full-circle baffle that's designed to keep parts in the media mass constantly for faster, more precise processing, has a 12-cubic-foot, urethane-lined tub for parts protection. Other spiral-bottom models initially available have tub capacities of 8 and 15 cubic feet; custom-designed models offer capacities of as much as 100 cubic feet. The spiral design features automatic separation of parts from he abrasive media, at predetermined intervals according to finishing requirements. Its separation screen surface is longer than other round-bowl designs, which permits faster separation of parts and machine unloading.

The unit is engineered to fit and move many different parts positively over the separating dam without jamming or hitting each other on the screen. The tub can also serve as a through-feed or one-pass machine when the dam is held in the "up" position.
