摘要： A vertical shaft impact crusher has an vertically adjustable feed tube disposed within a throat between a feed hopper of the crusher and the crusher lid of the housing. The feed tube may be adjusted in predetermined discrete increments to within a predetermined distance above an impeller table of the crusher within the housing of the crusher and without removing the hopper of the crusher during such adjustment. The adjustment is achieved by rotating an adjustment ring disposed at an interface between a hopper portion and a lid portion of the throat between the hopper and the lid. The adjustment ring may be held between to adjacent throat flanges to rotate circumferentially about a vertical crusher axis. The feed tube is a two-piece tube which includes an upper, re-usable portion and a lower expendable portion. The feed tube is held within a carrier tube which includes circumferentially spaced adjustment steps. The adjustment ring includes radially inward extending lugs which engage respective steps to support the feed tube at a height determined by the vertical position of the respective steps with respect to the carrier tube. As the ring is rotated in one predetermined direction, the lugs move off one set of steps and the tube drops until the lugs engage an adjacent set of steps of the carrier tube. A circumferential movement of the adjusting ring in the direction opposite to the adjustment rotation of the ring cuases the lugs to engage an undercut disposed at an inner end of each adjustment step.
摘要翻译：垂直轴冲击式破碎机具有设置在破碎机的进料斗和壳体的破碎机盖之间的喉部内的可垂直调节的进料管。进料管可以以预定的离散增量调整到在破碎机的壳体内的破碎机的叶轮台上方的预定距离内，并且在这种调节期间不移除破碎机的料斗。通过旋转设置在料斗和料斗之间的喉部的料斗部分和盖部分之间的界面处的调节环来实现调节。调节环可以保持在相邻的喉缘之间，以围绕垂直的破碎机轴线周向旋转。进料管是两件式管，其包括上部可重复使用部分和下部可消耗部分。进料管保持在载体管内，其包括周向间隔开的调节步骤。调节环包括径向向内延伸的凸耳，其接合相应的台阶以将进给管支撑在由各个台阶相对于承载管的垂直位置确定的高度处。当环沿一个预定方向旋转时，凸耳离开一组台阶，并且管滴下直到凸耳接合载体管的相邻的一组台阶。调节环在与环的调节旋转相反的方向上的圆周运动使得凸耳接合设置在每个调节步骤的内端处的底切。
