A blade plate for crushers to be installed on a fixed side or a moving side, includes a base material part and many blade parts arranged on the surface of the base material part. The blade part includes a diamond blade part having an edge formed of a corner between a belt-like part and an inclined part, and a chevron blade part which is configured in a polyhedral shape having an edge formed of a corner between a cross-shaped tip end belt-like part and a foot part and an edge formed of a corner between an inclined belt-like part and a foot part, and which is bound to an intersection place of the diagonal lines of the diamond blade part. Also provided is a crusher which utilizes the blade plate.

A jaw crusher, a crushing plant, and a method for using a crusher. A toggle plate is coupled between a pitman and a rear end of the jaw crusher with bearings at the ends of the toggle plate. A bearing holder for the bearing is present at least at one end of the toggle plate. The bearing is transferred continuously in the bearing holder to a desired location between an upper limit and a lower limit, inclusive of the upper and lower limits, with a transfer member of the bearing holder, and thus the operating angle of the toggle plate in relation to a frame of the crusher and the stroke of the crusher are changed.

A crusher bucket comprises a frame in which there are defined a material inlet and a material outlet and a material flow direction from the inlet to the outlet, crushing elements comprising a movable jaw and a fixed jaw which are received in the frame, a motor which can actuate the crushing elements, and a housing in which the motor is at least partially received. The housing is laterally defined by opposite side walls of the frame and is further delimited by a lower wall which faces the movable jaw and by an upper wall which are opposite each other and which extend between the side walls of the frame.

A crusher bucket comprises a frame, crushing elements comprising a movable jaw and a fixed jaw which are received in the frame, and an adjustment device which can change a distance between the jaws at an outlet of the material. The adjustment device comprises a strut having a first end and a second end which are opposite each other and which are received in a first seat which is defined in the frame and in a second seat which is defined in the movable jaw, respectively, and one or more spacers which are or can be removably inserted between the first seat and the first end of the strut through a first opening which is constructed in a side wall of the frame.

A system including a nearly horizontal jaw movable to reduce a size of frangible material, a stationary cover around a top side of the jaw, an area is defined between an outer surface of the jaw and an inner surface of the cover, and a drive mechanism to cause the jaw to move to vary the area between the cover and the jaw to reduce the size of frangible material within the area. Another system and method are also disclosed.
