場合でも同様に交換しなければならない。However, the rotary blades 55 and 56 that crush and crush in this way have a reduced crushing ability if the wear amount of the corners increases, so that the crushing ability is reduced when worn. Must be replaced to maintain. In addition, since the rotary blades 55 and 56 crush various crushed objects such as plastic and wood, some crushed objects may be worn in a short time, and the blades must be replaced in a short time. Sometimes you have to. further,
Even if a part of the rotary blade is damaged due to the presence of a hard object in the crushed object, the same must be replaced.

下してしまう。However, the rotary blades 55, 56
Normally, the entire blade is formed integrally, so that even if the blade edge is broken, the entire blade must be replaced. The work of replacing the entire blade in this manner is a work in which the drive shaft of the rotary blade is disassembled and replaced, requiring a great deal of time and labor. In addition, the crusher is in a stopped state during such an exchange operation, so that the throughput of the crusher decreases.
【０００７】そのため、回転刃が損傷したとしてもその
交換が容易なせん断破砕機が切望されている。[0007] Therefore, there is a strong demand for a shear crusher that can easily be replaced even if the rotary blade is damaged.
