System and method for dual roller crushing

A crusher device comprising:

• 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 the center block assembly further comprises diametrically-opposing arcuate plate surfaces at the first crushing jaw surface and at the second crushing jaw surface, and wherein the center block assembly comprises a quasi-X shape with lateral sides that connect to the diametrically-opposing arcuate plate surfaces and at least one diametrically-opposing medial surface;
• a first dual non-overlapping crushing roller mounted in space relation from the diametrically-opposing arcuate plate surface at the first crushing jaw surface;
• a second dual non-overlapping crushing roller mounted in space relation from the diametrically-opposing arcuate plate surface at the second crushing jaw surface;
• 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 the first dual non-overlapping crushing roller, reach an end of the first direction, and subsequently return to the starting location by moving in a second direction.
