PURPOSE:To improve the treatment efficiency in a decomposing chamber by providing this crude refuse treating device with a pair of revolving shafts for driving and rotating the pulverized materials of a pulverizing device parallel and pulverizing rods of a comb-tooth shape intersecting approximately orthogonally with the revolving shafts and specifying the shapes of these pulverizing rods. CONSTITUTION:This crude refuse treating device has a pair of the revolving shafts 22 which are parallely juxtaposed with each other and are driven to rotate the pulverized materials 21 of the pulverizing device 20 in the pulverizing chamber F and the plural pulverizing rods of the comb-tooth shape intersecting approximately orthogonally with the revolving shafts 22 so as to communicate with each other. The pulverizing rods 23 are formed to an approximately rhombic shape in section, of which one of the diagonal lines is along an axial direction. Crude refuse is then lifted upward by the comb-tooth-shaped right and left pulverizing rod arrays and are thereby sheared and finely segmented. The corner parts of the approximately rhombic shape in section come into contact with the crude refuse at this time, by which the crude refuse is surely parted. Further, the crude refuse is forcibly parted laterally after the parting. The pulverizing efficiency is thus improved. |
