Moving jaw hang directly on the eccentric shaft at the top, as a crank and connecting rod, directly driven by the eccentric shaft eccentric, the bottom of the moving jaw hinge thrust plate supported on the posterior wall of the rack. When the eccentric shaft rotates, moving jaw points on the trajectory is carried by some circular lines (radius equal to eccentricity), downward into a oval, the oval bias along with a downward trend until the trail of the junction between the lower part and trust plate becomes a arc. Horizontal travel of upper part is about 1.5 times that of the lower, so that meet the needs of compression for crushing lump ore of the upper crushing chamber. In the meanwhile, the entire vertical travel of the moving jaw is larger than the horizontal travel, especially the discharge orifice and its vertical travel is about 3 times that of horizontal travel, hence fostered discharge and increase productivity. Practice has shown that mini crusher, under the same conditions, production capacity of double toggle mini jaw crusher is about 30% higher than that of single toggle mini jaw crusher. However the wear of the jaw is too fast and smashing is serious.As the machines moving jaw points on the trajectory is more complex, it is called complex swing Jaw Crusher as well.

Compared with the single toggle mini jaw crusher, double toggle mini jaw crusher has the following advantages: it is more light weighted, less widget, structured more compact, better filled degree of broken cavity, loaded material block was uniform broken, and the productivity is 20-30% higher than the same specification single toggle...
