Abstract: A crusher assembly for a jaw crusher having a swing jaw and a crusher jaw having teeth formed on the breaking sides thereof, the crusher jaw comprising end faces at the opposite ends thereof, wherein a clamping piece having a clamping surface acts on the one end face (35) and the other end face (35) is supported on a clamping piece, wherein the clamping piece and the clamping element are interchangeably connected to the swing jaw, wherein the swing jaw comprises a head part having a pivot bearing on the end region thereof facing away from the clamping piece, and wherein the crusher jaw at least partially covers the region of the swing jaw in front of the pivot bearing.

Abstract: A crusher bucket comprising a casing in which there are mounted crushing means comprising a fixed jaw and a movable jaw, in which the movable jaw is supported on the casing by means of a pair of eccentric shafts, wherein at least one of the eccentric shafts is directly fixed to the side walls of the casing.

Abstract: A jaw crusher, a mineral material processing plant and a method for processing mineral material. The jaw crusher includes a fixed jaw and a movable jaw for forming a crushing chamber therebetween which is open at the top. The fixed jaw includes a first wear part mounted thereto and the movable jaw includes a pitman and a second wear part mounted thereto. The pitman is rotatably mounted to a first eccentric shaft. The pitman is further rotatably mounted to second eccentric shaft configured to guide the stroke of the movable jaw to create a movement pattern with a substantially linear crushing stroke, wherein the eccentricity of the second eccentric shaft is larger than that of the first eccentric shaft.

Abstract: A housing assembly for a rock crusher having an eccentric shaft. The housing assembly has an interior side and an exterior side and comprises a first housing portion having an inner side, an outer side, and a plurality of grooves and being removably attached to the rock crusher, and a second housing portion having a plurality of grooves and being removably attached to the first housing portion. The housing assembly also comprises an inner ring having at least one inner ring housing groove and at least one inner ring pitman groove and being disposed on the interior side of the housing assembly, and an outer ring having at least one outer ring groove and being disposed on the exterior side of the housing assembly. The housing assembly is disposed around the eccentric shaft. A method for removably housing a bearing assembly on a rock crusher.

Abstract: A jaw crusher movable jaw support frame mounts a linkage assembly for suspending a movable jaw in a floating relationship within a jaw crusher relative to a stationary jaw. The support frame includes reinforcement regions extending along a main force transmission wall to absorb and transmit loading forces imparted to the support frame from the movable jaw.

Abstract: A gyratory crusher comprises a first crushing shell mounted on a crushing head, and a second crushing shell mounted on a machine frame, a crushing gap being formed between said first and second crushing shells. A method of controlling the operation of said crusher comprises measuring a parameter being representative of the stresses to which the crusher is exposed during the crushing of material, determining an average value of said parameter, determining a deviation value of said parameter, calculating a peak value based on said average value and said deviation value, comparing said peak value to a reference value, and controlling the operation of the crusher in view of said comparison between said peak value and said reference value.

Abstract: There is described a crushing plant and a method for controlling the same. The crushing plant involves a gyratory crusher (1) with means for controlling a minimum gap in a crushing chamber, and is driven by a diesel engine (18). A load value is retrieved from the diesel engine e.g. by means of a J1939 interface. If the retrieved value exceeds a predetermined threshold value, the minimum gap is increased. Thereby it can be avoided that the diesel engine stalls; such that continuous operation of the crushing plant may be ensured.

Abstract: Flap carriers fold spanwise (about chordwise axes) into the wing but are moved down together through pivotal linkage; the flaps are protracted and retracted through pivoting of the carriers relative to each other on spanwise axes. On retraction, the entire assembly fits into the wing so that the flow determining contour thereof remains undisturbed.
