Abstract: A jaw crusher unit for use in crushing stone and other crushable material has a fixed jaw and a movable jaw which define a crushing zone therebetween. A drive mechanism coupled with the movable jaw operates to rock the movable jaw to and fro to crush material in the crushing zone. A link mechanism sets a space between the lower end of the movable jaw and the fixed jaw and thereby controls the discharge of crushed material from the lower end of the crushing zone. A removable wear plate is mounted on a mounting face of at least one of the jaws by a wedge arrangement coupled with a power-operated linear actuator. The linear actuator moves the wear place into and out of engagement with the mounting face to facilitate replacement of the wear plate.

Abstract: A two part endless conveyor which is adjustable between an in-line operative position and a folded position. The conveyor has two folding conveyor parts which are mounted to the frame of a material handling apparatus. A folding mechanism interconnects the two conveyor parts. It includes a coupling block or linkage which interconnects the two folding conveyor via a respective one of a pair of pivots and a pair of linear actuators associated with the conveyor parts. Each actuator rotates the coupling block through approximately 90° about the respective pivot, whereby the folding mechanism, under the action of the two linear actuators, can adjust the conveyor parts between the in-line operative position and the folded transport position.

Abstract: A bulk material processing apparatus having a longitudinally extending main frame and a supply conveyor mounted on, and extending length wise of the main frame to convey a supply of bulk material from a forward lower end of the conveyor to an upper and rearward discharge end. A material processing device is mounted on the main frame and arranged to receive material from the discharge end of the supply conveyor, to process the material, and to discharge processed material. A discharge conveyor is mounted on the main frame below the processing device to receive processed material discharged by the processing device and to discharge the material to a discharge point located rearwardly of the apparatus. The processing device is moveable between a raised operating position and a lowered transport position. Likewise, the discharge conveyor is moveable between a raised operative position and a lowered inoperative position.

Abstract: A screening device for screening bulk material and having a screen deck with a loading end and a discharge end, and a frame on which the screen deck is mounted. The screen deck includes a primary screening section and a secondary screening section arranged downstream of the primary section. The primary screen section is adjustable to screen at an angle relative to the secondary screening section.
