Dewatering-Drying System Removes Oversize, Undersize Particles
New 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. The screener, a 30-inch-diameter Vibroscreen model K30-2-SS, together with the 40-inch-diameter model K40/48-1FBD-SS dryer, removes up to 50 gallons of water per minute, and dries up to 700 pounds 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. 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 dewatered pellets 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 dryer. Undersize fines and water pass through the lower screen onto an integral metal chute and through a third spout for reprocessing.
