ABSTRACT:
A paper sludge drier includes a somewhat attrition style mill discharging to a horizontal, rotary drum drier. The mill has two mill plates facing each other. As one rotates relative to the other, sludge is broken down as it passes between the plates. The sludge flows generally from the center of the plates and outward through grooves running radially across the plates. The sludge is subsequently dried in the horizontal drum which has an integral internal screw that conveys the sludge through the drum. The sludge drier reduces the moisture content of the paper sludge from over 50 percent down to less than 20 percent.
