Abstract
A rotary crushing apparatus includes a container (including a stationary drum, a rotating drum, and a top plate) into which a processing object containing raw material soil is fed. A rotating shaft extends in the vertical direction, and an impact member rotates in the rotating drum by the rotation of the rotating shaft to crush the processing object. Then, the rotating shaft is provided in such a way as to penetrate the top plate 10a, and the rotating shaft is rotatably held via ball bearings provided in the vicinity of the top plate. In addition, the lower end of the rotating shaft is a free end.
