A blade plate for a crusher, where in the blade plate is normally installed on a fixed side or a movable side, includes a base material part, and a large number of blade parts arranged on a surface of the base material part. The blade parts include a rhombic blade part that forms a rhombic blade at a corner between inclined portions and a mountain-shaped blade part that is formed in a polyhedron shape in which a cross-shaped tip blade is formed at a corner between chipped portions provided at inclined portions. An inclined blade is formed at a corner between the inclined portions and is coupled to the rhombic blade part at an intersection point of diagonals of the rhombic blade part and a crusher using the blade plate.

A jaw crusher has frame side walls, a rear end connected to the side walls, an eccentric supported by the side walls, a pitman supported by the eccentric, a toggle plate connected between the pitman and a middle section of the rear end including a cross wall. The rear end has a rear end support connected to the cross wall and located on a center plane of the cross section of the rear end. An upper and lower rear cross beams are fixed to the side walls. The upper and lower rear cross beams each have a vertical wall and horizontal ribs connected to the vertical wall. A crushing plant is also disclosed with a body and the jaw crusher mounted on the body.

A pulverizing attachment for an excavator and a method of removably rigidly retaining teeth to one or more jaws of a pulverizer. A plurality of tooth members each have a longitudinal slot with a cross-sectional shape and a relief slot extending substantially transverse to the longitudinal slot producing a flexible end portion capable of deflection upon application of a longitudinal compression force. The tooth rails having a complimentary cross-sectional shape to the longitudinal slot slidably receive the tooth members. The complimentary shape of the longitudinal slot and tooth rail in cooperation with a longitudinal compression force applied to deflect the flexible end portions of each of the tooth members rigidly retains the tooth members on the tooth rails fixed to the pulverizer jaws.

A hydraulically activated shear is provided. The shear includes: a first jaw; a second jaw sliding past the first jaw in a shearing motion; and a first cutting plate attached to at least one side of the first and second jaws, the first cutting plate defining a shear edge and a shear surface, the shear surface having a positive camber with respect to a plane perpendicular to the jaws, wherein at least one of the first and second jaws is actuated by a hydraulic cylinder.

A jaw crusher retraction assembly having a base, a first and second mount boss, a resiliently biased component and an actuating cylinder. The cylinder and resiliently biased component are mounted axially between respective regions of the base and the first and second bosses so as to minimize stress in the retraction assembly components and to provide a compact overall design.

A jaw crusher assembly comprises a jaw crusher a jaw liner clamping tool for clamping a jaw liner to a jaw of the jaw crusher. The clamping tool comprises a clamping head pivotably coupled to a shaft, and a releasable fastening mechanism. The shaft passes through the jaw and its free end is fastened to the jaw by the fastening mechanism, which is tightened to cause the clamping head to exert a clamping force to hold the jaw liner in place. The clamping tool facilitates safe installation of the jaw liners.

A jaw crusher including a fixed jaw and a movable jaw for forming a crushing chamber therebetween which is open at the top, the fixed jaw including a first wear part mounted thereto and the movable jaw including a pitman and a second wear part mounted thereto. The crushing chamber includes an upper section, a middle section, and a lower section having equal heights (h). The pitman is bearing-mounted to an eccentric shaft and to at least one slide member. The at least one slide member is configured to slide in a direction substantially perpendicular to the vertical diagonal of the crushing chamber. A method for crushing mineral material in a jaw crusher or a crushing plant is also disclosed.
