SPIRAL-BOTTOM ROUND-BOWL MACHINE

ALMCO, Inc., the world’s largest manufacturer of automated metal parts deburring and finishing equipment, has expanded its line to include a spiral-bottom round-bowl unit with a unique full-circle baffle that keeps parts in the media mass constantly for faster, more precise processing. The Model SBB-12 has a 12-cubic-foot, urethane-lined tub for parts protection. Other spiral-bottom models available from the manufacturer have tub capacities of 8 and 15 cubic feet, while custom-designed models offer capacities up to 100 cubic feet. ALMCO’s spiral design features automatic separation of parts from the abrasive media, at predetermined intervals according to finishing requirements. Its separating screen surface is longer than other round-bowl designs, which permits faster separation of parts and machine unloading. The SBB-12 is engineered to lift 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 thru-feed or one-pass machine – adding to the SBB’s versatility – when the dam is held in the up position. Key benefit of the spiral design is its up-hill tub bottom that provides a larger rolling mass right to the screen area. This allows larger parts to be lifted up the dam and over the area. Larger parts can be processed on the tub because of greater clearance between the screen and tub bottom. Specifications of the SBB-12 include a 7.5-hp drive, a 13-inch diameter tub cross section, an overall diameter of 66 inches, and a machine height of 44 inches. Separate from a free-standing control panel, floor space requirement is less than 6 feet square.
