Although simple jaw crusher complex swing and swing both types, but their works are substantially similar, except that the jaw movement trajectory of a greater difference. Simple swing jaw crusher, because the movable jaw is hanging on the support shaft so that when the movable jaw is reciprocated, the trajectory of each point on the movable jaw are arc-shaped, and the horizontal stroke is small at large, and to movable jaw bottom (at the port of discharge) is maximized. Since the fall of the ore crushing chamber, the upper portion are big nugget, so often fail ore crushing amount of compression required, so the upper part of the chunk of ore, crushed to be repeated several times before crushing.
Most crushing load is concentrated in the lower portion of the crushing chamber, there is no uniform throughout the work jaws, thereby reducing the production capacity of the crusher. Vertical stroke while this crusher small, grinding stripping effect of discharge is slow. But jaws wear lighter, less over crushed product. Complex swing jaw crusher, because of its jaw is movable rod crank link mechanism, driven by the eccentric shaft, the movable jaw trajectory point approximate oval, elliptical degree is small under the large, its upper part approximately circular.
