Abstract
Abstract A continuous process for drying titanium sponge in which wet sponge is continuously conveyed to an evacuated drying chamber. A continuous conveyor in the drying chamber transports the wet sponge through a heated zone toward a discharge end. Vaporized moisture from the sponge is condensed in the vacuum pump which is a liquid jet pump which acts as a highly efficient condenser. The dried sponge is then continuously moved into storage hoppers.
