That is, when crushing the work 1, at a relatively early stage when the work 1 starts to contact the rotary blade 3, the work 1 is still loosely filled in the supply cylinder 2, so that the plunger 6 The pressing force is weak. As the crushing progresses, the work 1 is densely filled in the supply cylinder 2, and the pressing force gradually increases.

Further, even after the work 1 is densely filled in the supply cylinder 2 and the pressing force by the plunger 6 reaches a predetermined value, the work 1 near the lower part of the supply cylinder 2 is rotated. Before the blade 3 is in contact with the blade 3 for a short time and is not sufficiently crushed, it is drawn into the gap between the rotary blade 3 and the fixed blade 17. As a result, similarly, a uniform crushed particle size cannot be obtained.

As described above, the conventional crusher has a problem that it is difficult to obtain a uniform crushed particle size. In addition, in order to improve the uniformity of the crushed particle size using a conventional crusher, it is necessary to classify the crushed work 1 and crush it again. As a result, the efficiency of the crushing operation is reduced. There was also a problem to say.
