A jaw crusher machine has a double-acting jaw (110) that linearly reciprocates to reduce abrasive wear and tilts back and forth during the crushing and discharge strokes to create a peristaltic action that, depending on the direction of rotation of the driven shaft (118), aids the ingestion, crushing and discharge of either hard or soft feed materials.

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 tool attachment system for demolition, recycling, and/or material processing applications wherein a platform is part of a jaw of a jaw set. A segment with working surfaces is attached to the platform such that the segment shields the platform from a workpiece. Additionally, the segment may be customized for a particular task thereby providing optimum performance.

A crusher device includes a jaw having a center block assembly with a first crushing jaw having surface on a first vertical side and a second crushing jaw having a surface on a second vertical side of the center block assembly wherein each surface has a diametrically-opposing arcuate plate surface, a first dual non-overlapping crushing roller mounted in space relation from the diametrically-opposing arcuate plate surface, a second dual non-overlapping crushing roller mounted in space relation from the diametrically-opposing arcuate plate and a toggle mechanism coupled to the center block assembly to create a toggling motion during a toggle cycle to move the center block assembly, which causes the center block assembly to, from a starting location, move in a first direction toward a first roller of the first jaw crushing channel, reach an end of the first direction, and subsequently return to the starting location.

To provide a construction technique of a stone material crushing tool which can prevent complication of working environment. An electrically-driven stone material crushing tool including a motor having an output shaft, a motion converting mechanism to convert a rotating movement from the output shaft to a linear movement, and a crushing member to crush the stone material by clamping by means of the linear movement of the motion converting mechanism.
