Witte Co. Vibrating Dewatering Screens for Fluid Bed Drying


Vibrating dewatering screens from process equipment manufacturer The Witte Co. of Washington, N.J., remove excess moisture from saturated materials to allow fast, efficient drying downstream in a fluid bed dryer.

Draining the moisture mechanically at low cost instead of using heat energy, the vibrating dewatering screens reduce the moisture content of coarse products in a slurry to 2 to 4 percent while continuously feeding the material to the dryer at up to 20,000 lb./hour in a form that allows the remaining moisture to be more efficiently removed at a far lower cost than by drying alone.

With 1,000 BTU’s of heat energy required to evaporate a single pound of water, the integrated dewatering and drying system offers significant cost savings in common applications.

An effective alternative to filter presses and dewatering screws, the Witte vibrating dewatering screens are ideal for frac sand and other products where a very low moisture level is required at dryer discharge and cost is an important consideration. For added efficiency, the Witte dewaterer may be fitted with spray nozzles to integrate rinsing steps into the process.
