MILLBURN, NJ A new self-contained Circular Vibratory Screener-Fluid Bed Dryer System from Kason Corporation removes oversize and undersize material, and dries on-size material.
The pre-packaged system scalps and de-dusts 2500 to 3000 lbs (1134 to 1361 kg) of bulk material per hour using a double-deck, 30 in. (762 mm) diameter circular vibratory screener, and then dries the material in a 40 in. (1016 mm) diameter circular vibratory fluid bed processing system.
The screener is equipped with an imbalanced-weight gyratory motor that vibrates the screening chamber which is
| suspended on springs. Oversize particles travel in controlled spiral pathways from the center of the upper screen to a spout at the screen's periphery where they are discharged for reprocessing. On-size particles falling onto the lower screen travel in controlled spiral pathways to an extended spout at the screen's periphery that leads to the fluid bed drier. Undersize material passes through the lower screen onto an integral metal chute and through a third spout for reprocessing.
The circular fluid bed dryer is reportedly half the size and weight of a rectangular fluid bed dryer of equivalent capacity and
| allows consolidation of all primary system components. Inherent strength of the circular processor eliminates the need for heavy-gauge walls and cross braces otherwise required to withstand continuous vibration, allowing vibratory motors to be downsized.
The circular unit also requires only one air inlet and outlet and has fewer weld seams, reducing overall size and construction cost, especially when finished to 3-A, FDA, and BISSC sanitary standards. Cleaning time is cut by more than 50 percent due to the reduction in interior seams and accessibility afforded by a quick-disconnect housing.
