摘要： A blockage clearance apparatus for a crusher that has a housing and a lid and at least one anvil mounted to the lid for crushing material. The housing contains a rotatable rotor with radial blow bars against which crushable materials are forced during operation. In operation, the materials are fed into the crusher, impacted by at least two blow bars and thrown against at least one anvil for crushing. The blockage clearance apparatus includes means for moving the lid and the anvil relative to the rotor during operation, means for inhibiting the material in the housing from exiting the housing when the lid is spaced from the housing during operation, and means for stopping movement of the lid relative to the rotor.

摘要： A mobile screening machine with a frame on tracks, having a hopper and a main conveyor mounted to a frame. The main conveyor conveys particulate matter from the hopper to a screening device positioned beneath the upper end of the main conveyor. The particulate is screened into three grades of coarseness, with the coarsest falling into a chute, the middle coarseness falling onto one lateral conveyor and the finest falling onto an underscreen conveyor, which preferably is driven downhill onto another lateral conveyor. The tracks permit the machine to be driven around the work site and onto and off of a trailer, and the entire machine can be remotely controlled. The downhill conveyor permits loading of the hopper from both sides of the frame.
摘要翻译：一种在轨道上具有框架的移动筛分机，具有料斗和安装在框架上的主输送机。主输送机将颗粒物质从料斗传送到位于主输送机上端下方的筛分装置。颗粒被筛选成三个等级的粗糙度，最粗糙地落入滑槽中，中间的粗糙度落在一个侧向输送机上，并且最好地落在一个下部的筛网输送机上，该输送机优选地被下坡驱动到另一个侧向输送机上。轨道允许机器围绕工作现场进行驱动，并且可以通过拖车进行和关闭，整个机器可以被远程控制。下坡输送机允许从框架的两侧装载料斗。

摘要： A vibration-reducing eccentric weight system mounted to the driveshaft of a screen box in a portable screening plant with the eccentric weight system's center of gravity on the driveshaft's axis of rotation. The eccentric weight system includes a weight that is radially slidably mounted to the driveshaft, but biased so that its center of gravity is spaced from the driveshaft's axis of rotation during slow and no rotation. Upon rotation above a preselected speed, the centrifugal force displaces the weight radially outwardly. This causes a gradually increasing vibration corresponding to gradually increasing distance between the weight's center of gravity and the driveshaft's axis of rotation.

摘要： A screening plant including a housing to which first and second screen boxes are reciprocatably mounted. The screen boxes are coplanar and the inner peripheral edge of the first box is adjacent the inner peripheral edge of the second box. Separate prime movers, such as hydraulic motors, are drivingly linked to the independently mounted screen boxes. The screen boxes are separated by a gap over which a beveled cap is mounted.

摘要： A screening machine on a frame with a hopper having a conveyor belt. The conveyor belt discharges particulate material poured into the hopper into a rotating barrel screen or vibrating planar screen for sifting the material. A hammermill apparatus is pivotably mounted on a hood member to an arm that is pivotably mounted to the frame of the machine. The hammermill is positioned above the conveyor belt at the discharge end. The hammermill can pivot upwardly relative to the arm upon striking a large object on the conveyor belt, and a spring mounted to the arm and the hood biases the hammermill back to its original position. A hydraulic ram is drivingly linked to the arm for manually or automatically displacing the hammermill relative to the conveyor belt.

摘要翻译：减震偏心重量系统安装在筛分机的筛箱的驱动轴上，偏心重量系统的重心位于驱动轴的旋转轴上。偏心重量系统包括径向可滑动地安装到驱动轴上的重物，但是偏压使得其重心在慢速和不旋转期间与驱动轴的旋转轴线间隔开。当旋转高于预选速度时，离心力径向向外移动重量。这导致逐渐增加的振动，对应于重量的重心和驱动轴的旋转轴线之间的逐渐增加的距离。
