Primary jaw crusher is typically of the square opening design, and secondary jaw crusher is of the rectangular opening design. Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw board, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates decide the crusher product size gap, or the size of the crushed product from the jaw Crusher. The rock remains in the jaw until it is small enough to pass through the gap at the bottom of the jaws.
