CONSTITUTION:A dehydrated cake K contains more than 60-65% moisture after the materials such as various kinds, of sludges as raw sewage, dirty sludge or sewage, drainage sludge, city water drainage sludge, and low quality sludge, etc., are burnt out. The cake K is fed ints a throwing-in hopper 1 to fire bed 3 for drying by a pusher 2, resulting in the formation of a certain thickness of cake layer on fire bed 22 for drying. The cake layer K on the fire bed 22 for drying is sent successively to the front lower stages by the moving of the movable fire grating 22a and a comperatively large head of the fire grating. Thus, by a large difference in level between fire grating 22a and 22b, and by the existence of gas blowing-in pipe 23 to jet a circulating exhaust gas G in high temperature drying, drying is more rapidly promoted because the cake layer is divided into up and down parts to get a stirring action and simultaneously the circulating gas G of high temperature is supplied into the cake layer K.
