PURPOSE: To efficiently grind waste refuse. CONSTITUTION: A spiral groove part 68 is provided to the inner wall of a waste refuse housing part 61 and a grinding part 70 having a large number of sharp projections is arranged to the lowermost part of a funnel part 61a. When waste refuse is charged in the waste refuse housing part 61 and an upper lid 64 is closed, the driving of a rotary shaft 69 is started and the upper lid 64 is guided by the spiral groove part 68 to fall and, at this time, the waste refuse is downwardly pressed by the rear surface of the upper lid 64 to be brought into contact with the rotating grinding part 70 under pressure to be ground. By this constitution, the waste refuse is finely ground to be certainly decomposed by bacteria. |
