摘要： The tip of a spider arm of a rotor of a reversible hammer mill is protected from wear and damage by a pair of replaceable caps. Each of the caps has a protective shroud for protecting a portion of the extremity of the tip and an adjacent edge of the spider arm. The caps also each have a relatively narrow web which is sized to fit within and cooperate with the web of another cap in substantially filling an open-ended slot in the spider arm. The webs of the two caps are introduced into the slot from opposite ends of the slot and held in place by a hammer pin which extends through collinear openings in the webs and the spider arm.

摘要： Replaceable protective means for protecting an end disc of a rotor shredder from excessive wear includes a protective cap of hardened, wear resistant metal, and at least two pins and washers of readily weldable metal. The protective cap has a U-shaped channel for receiving a curved portion of the periphery of the end disc. The opposed walls of the U-shaped channel each have at least one pair of pin-receiving openings and the openings in each wall are aligned with those in the opposed wall. When the cap is positioned in place on the end disc with the pin receiving openings in the opposed walls of the cap aligned with openings which extend through the end disc, the pins which have enlarged heads at one end which are larger than the openings in the disc can be inserted into the aligned openings and secured in place by welding a washer which also is larger in diameter than the openings in the disc to the other end of each of the pins. The protective cap is thus retained in place on the end disc by the welded pin and washer combinations which are not directly attached to either the cap or the end disc. The protective cap may be provided with a dependent skirt so that it protects not only the edge or periphery of the end disc, but also interior areas which are subject to wear.

摘要翻译： 用于保护转子粉碎机的端盘免受过度磨损的可更换的保护装置包括硬化，耐磨的金属的保护帽，以及容易焊接的金属的至少两个销和垫圈。 保护帽具有用于接收端盘周边的弯曲部分的U形通道。 U形通道的相对壁各自具有至少一对销接收开口，并且每个壁中的开口与相对的壁中的开口对准。 当盖子定位在端盘上的适当位置时，盖的相对壁中的销接收开口与延伸穿过端盘的开口对齐，在一端具有扩大头部的销比这些开口大 盘可以插入到对准的开口中并且通过焊接直径大于盘中的开口的垫圈到每个销的另一端来固定就位。 因此，保护​​盖通过不直接附接到盖或端盘的焊接销和垫圈组合而保持在端盘上的适当位置。 保护盖可以设置有从属裙部，使得其不仅保护端盘的边缘或周边，而且保护受磨损的内部区域。
