Abstract: A material processing apparatus comprising a body, and a conveyor that is movable between a deployed state and a transport state. The conveyor comprises a feed end, a discharge end and conveying means configured to carry material from the feed end to the discharge end. The discharge end is coupled to the body and, in the deployed state, the conveyor extends from the body with the feed end being spaced apart from the body by the conveying means. In the transport state, the conveyor is folded with respect to the body.

Abstract: A cone crusher including a conical body; a mantle removably positioned over the conical body, and an assembly for securing the mantle on the conical body. The assembly includes a retainer for pressing the mantle onto the conical body, and an adapter located between the retainer and the conical body. The adapter is secured on the conical body and the retainer is movably mounted on the adapter.

Abstract: A material processing apparatus comprising: a base; a first material processing unit, for example a crusher and; a feed conveyor. The feed conveyor and the second material processing unit are both movable with respect to the first material processing unit and with respect to each other so that material can be fed into the first material processing unit directly from the feed coneyor, or indirectly from the feed conveyor via the second material processing unit. The second material processing unit can be stored beneath the feed conveyor when not in use.

Abstract: A jaw crusher having a fixed jaw and a swing jaw disposed between opposing side walls of the jaw crusher. The swing jaw is movable relative to the fixed jaw for generating impelling forces to crush material present between the two jaws. The jaw crusher includes a cross beam which extends between the opposing side walls and a toggle plate is provided between a rear face of the swing jaw and the cross beam. Pressure cylinders are provided for applying a load to the cross beam, to provide a reaction to forces generated during movement of the swing jaw. The jaw crusher comprises a locking arrangement for selectively preventing substantial movement of the cross beam against the action of the pressure cylinders.

Abstract: An aggregate processing apparatus comprising a conveyor support structure having a base section located at a side of the apparatus, a mid-section pivotably coupled to the base section and a head section pivotably coupled to the mid-section. The conveyor support structure is operable between a deployed state, in which the mid-section and the head section project from the side, and a transport state in which the mid-section is folded to extend across the first face and the head section is folded with respect to the mid-section to extend across an end face of the apparatus.

Abstract: A material screening apparatus is adaptable between a reduced-bearing mode and an additional-bearing mode. The apparatus comprises a screen box coupled to a frame and comprising at least one screen deck. A rotatable shaft is coupled to the screen box for imparting vibrational and/or oscillatory motion to the screen deck(s). Drive means imparts rotational motion to the shaft and a first set of bearings couples the shaft to the screen box. In the additional-bearing mode only, a second set of bearings couples the shaft to the frame. Changing between modes allows the screening characteristics of the apparatus to be adjusted.

Abstract: A support assembly for supporting a part of a machine, the support assembly comprising at least one support member for supporting a part of the machine on a base, the support member being slidably mounted on a mounting member on the base to be displaceable with respect to the mounting member between a retracted position and an extended position, a jacking leg extending from a lower end of the mounting member to be displaceable between a retracted position and an extended position, a ram acting between the jacking leg and the support member, said ram being operable to move the jacking leg between its retracted and extended positions and to move the support member between its retracted and extended positions to adjust the position of said part of the machine relative to the base.

Abstract: A folding mechanism comprising a first support; a second support pivotably coupled to the first support; an actuator operable to pivot said second support relative to said first support about a first pivot axis between a deployed position and a folded position; and an elongate support strut extending between said first and second supports, the support strut being adapted to permit movement of said second support about said first pivot axis when the support strut is in a first state, the support strut being adapted to retain said second support in said deployed position when the support strut in a second state; the support strut being coupled to the actuator such that the support strut is reconfigured between its first and second states as the actuator is operated to pivot the second support between its folded and deployed positions.

Abstract: A conveyor support structure for an aggregate processing apparatus, the support structure comprising a base section and a deployable boom structure. The boom structure includes a mid-section pivotably coupled to the base section, and a head section pivotably coupled to the mid-section. When the boom structure adopts a transport state, the mid-section extends at an angle of approximately 45° with respect to the ground surface. A pair of crossed head section supports are pivotably coupled between the base section and the head section and serve to guide the movement of the boom structure.

Abstract: A folding mechanism for a hopper flare, the mechanism comprising a linkage mechanism having a first track provided on a first support, a second track provided on a second support, and a link coupled to both the first and second tracks. The link is capable of riding simultaneously along each of the first and second tracks as the second support pivots about its pivot axis. The first track includes a locking track segment having a bearing surface oriented to resist, by engagement with the link, movement of the second support about the pivot axis in at least one direction.

Abstract: A crushing machine including a crushing means, a feed conveyor for feeding material to the crushing means, a detector for detecting metal in the material on the feed conveyor, and a bypass chute for the crushing means, the feed conveyor being movable between a normal operating position in which the material is fed to the crushing means and a bypass position in which the material is fed to the bypass chute, the arrangement being such that on detection of metal in the material, the feed conveyor is stopped and moved from the normal operating position to the bypass position so that the material with the metal is discharged into the bypass chute.

Abstract: A conveyor support structure for an aggregate processing apparatus, the support structure (20) comprising a base section (24) and a deployable boom structure (22). The boom structure includes a mid-section (28) pivotably coupled to the base section, and a head section (26) pivotably coupled to the mid-section. When the boom structure adopts a transport state, the mid-section extends at an angle of approximately 45° with respect to the ground surface. A pair of crossed head section supports (38, 40) are pivotably coupled between the base section and the head section and serve to guide the movement of the boom structure (22).
