Dewatering-Drying System Handles up to 50 Gallons Per Minute

February 9, 2010
The dewatering-drying system consists of a circular vibratory screener integrated with a circular fluid bed dryer that removes oversize and undersize particles, while dewatering and drying on-size material, according to the manufacturer. The 30-inch screener together with the 40-inch dryer, remove up to 50 gallons of water per minute, and dries up to 700 lbs of on-size particles per hour. The screener is equipped with an imbalanced-weight gyratory motor that vibrates the screening chamber, which is suspended on springs. The circular fluid bed dryer is typically 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.
