L. BASKET (Tumbler) SYSTEM
1. Basket (tumbler) Drive System
The basket (tumbler) is supported and driven by four (4) 11-inch (27.94 cm) diameter drive wheel assemblies.
Two (2) of these wheels are attached to a 1-1/2” diameter idler shaft, while the other two (2) are attached
to a 1-1/2” diameter drive shaft. Each of the wheels is fastened to the shafts by a taper lock bushing.
The idler shaft and drive shaft are each supported by two (2) 1-1/2” diameter pillow block bearings. These
bearings sit on slotted support channels and can be moved inward or outward by the adjustment bolts. This
results in raising or lowering the basket (tumbler).
The drive system consists of a shaft mounted gear reducer, two (2) V-belts, and a 5 HP (3.73 kw) drive
motor. Belt tension can be adjusted by tightening or loosening the gear reducer turnbuckle.
To keep the basket (tumbler) in the middle of the dryer a series of retaining wheels are used in the front and
rear of the dryer. The retaining wheels run along the vertical edge of the basket (tumbler) rings. These
keep the basket (tumbler) from rubbing on the front and rear panels of the dryer.
