ABSTRACT:
A process for disposal of wet sewage sludge by introducing a particulate material having BTU values, feeding the mixture to a grinding or milling apparatus in which the particulate material acts to prevent the sewage sludge caking in the apparatus during the reduction in the grinding or milling thereof, supplying hot gaseous medium to dry the mixture, with a portion of the hot mixture being recirculated to assist in the drying of the mixture as it is fed into the grinding or milling apparatus, and disposing of the resulting ground or milled mixture by burning with the aid of the BTU content of the particulate material.
