Pull-rod Spring
During the idling process of the jaw crusher, due to the inertial force of the movable jaw and the inertial force couple, the movable jaw and the toggle plate will separate, destroying the normal operation of the machine. In order to prevent this phenomenon from happening, a pull rod spring device is provided at the lower end of the movable jaw to ensure a tight fit between the movable jaw and the toggle plate.

Lost foam casting process
Our company adopts a new lost foam casting process. This technology is a new process with almost no margin and accurate molding. This process does not require mold taking, no parting surface, and no sand core, so the castings have no flash, burrs, and draft slopes. degree, and reduces dimensional errors caused by core combination. The surface roughness of castings can reach Ra3.2 to 12.5μm; the dimensional accuracy of castings can reach CT7 to 9; the machining allowance is up to 1.5 to 2mm. Compared with traditional sand casting methods, the machining time can be reduced by 40% to 50% , short production cycle.
