Abstract
A method and apparatus for improved settling and handling of sludge in a fused salt bath for treating materials is provided. The apparatus includes a tank divided into a work zone and a salt processing zone, with the salt processing zone having a salt recovery section and a salt heating section. A pumping device is provided which together with adjustable gate means, generate a relatively quiescent flow in the work zone allowing sludge to settle, and a relatively turbulent flow in the salt processing zone and especially the salt heating section, to keep the sludge in suspension.
