    • A crusher including a series of cutter units mounted on a pair of shafts arranged parallel to each other so as to rotate in the opposite directions to each other, wherein each of the cutter units is provided with a holder member which includes a flange portion and a boss portion, and a disc-shaped cutter blade secured detachably to the holder member and divided circumferentially into several segments, the cutter units on the respective shafts being so arranged that the disc-shaped cutter blades of every paired cutter units contact each other partly at their sides and that the disc-shaped cutter blade and flange portion of a cutter unit on one shaft are opposed to the boss portion of the mating cutter unit on the other shaft such that a space is formed between the peripheries of both cutter units; and each flange portion is provided with pawls along its outer periphery while each boss portion has provided along its periphery alternate ridges and recesses so designed as to maintain a substantially constant spacing between the outer periphery of the boss portion and the opposing periphery of the flange portion of the mating cutter unit during rotation of the cutter units.
    • 一种破碎机,包括安装在彼此平行布置的一对轴线上的一系列切割器单元,以便沿彼此相反的方向旋转,其中每个切割器单元设置有保持器构件,该保持器构件包括凸缘部分和 凸台部分和可拆卸地固定到保持器构件上的圆盘形切割刀片,并且被圆周地分成多个段,各个轴上的切割单元被布置成使得每对成对的刀具单元的盘形刀片部分地彼此接触 并且一个轴上的切割器单元的盘形切割刀片和凸缘部分与另一个轴上的配合切割器单元的凸台部分相对,使得在两个切割器单元的周边之间形成空间; 并且每个凸缘部分沿着其外周设置有棘爪,而每个凸台部分沿着其周边设置有交替的脊和凹槽,其被设计成在凸台部分的外周和凸缘部分的相对周边之间保持基本恒定的间隔 在切割器单元旋转期间的配合切割器单元。
