ABSTRACT:
A method and apparatus for dehydrating a metal hydroxide sludge, including depositing the concentrated metal hydroxide sludge containing approximately 60-80% water into a feed hopper, breaking up the concentrated sludge with rotary beaters and preferably a rotary breaker bar, then transferring the broken sludge through a feed auger to an elongated dehydrater chamber in which the sludge is conveyed longitudinally along the dehydrater chamber by a dryer auger continuously in contact with a longitudinally flowing hot gas. The moisture-laden hot gas is exhausted from the outlet end of the dehydrater chamber while the dryed sludge is deposited through a discharge port.
