Sludge Dryer
These dryers can be installed to load directly underneath a filter press or multiple disk screw press, or elsewhere in the plant. The sludge is dried through the heated liner of our units while being crushed and circulated through our screw blade system. The dryer liner uses an indirect heat source from steam, electric hot plates or gas fires.
