ABSTRACT:
Apparatus for disposing of wet sludge by conversion to a substantially dry product during grinding of the wet sludge in a drying atmosphere which promotes the separation of the grindings into coarse fractions and fine fractions so that the coarse fractions in the dried condition can be directed to enter the supply of the wet sludge for reducing the moisture content to prepare the mix of wet sludge and coarse fractions for grinding in a drying heat atmosphere to perpetuate the supply of coarse fractions for moisture reduction of the wet sludge and a supply of the fine fractions as a product of the apparatus.
