DESCRIPTION
A. TUMBLER SUPPORT AND DRIVE SYSTEM
1. Tumbler
The tumbler is made of five (5) 14-gauge stainless steel perforated panels, five (5) stainless steel lifting
ribs, and two (2) outer tumbler rings which have been machined on a lathe. The tumbler is a completely
welded assembly so the perforated panels are not removable.
2. Tiunbler Support System
The tumbler sits on eight (8) 11-inch diameter heavy-duty rubber roller wheels which support the
tumbler and drive it. Two (2) rubber wheels are pressed onto each of four (4) steel hubs. The steel hubs
are fastened to the 2-inch diameter drive shafts by taper lock bushings. Each drive shaft is supported by
two (2) 2-inch diameter heavy-duty roller bearings. The position of the tumbler is adjusted by moving
these bearings inward or outward by screwing in or unscrewing the four (4) bearing adjustment bolts.
