Working principle of overload Protection device of jaw Crusher
**
The working principle of the overload protection device is as follows: the fixed jaw is stationary and fixed on the inner wall of the equipment box. The motor drives the eccentric wheel to rotate through the pulley, thus driving the moving jaw to make the compound swing motion. Crushing materials. The piston rod of the cylinder is connected with the liner, and hinged with the spring pull bar at the lower end of the moving jaw, which determines the size of the discharge port and the size of the broken material particle. When the crushing chamber encounters a material whose crushing strength exceeds the specified value, The piston of the hydraulic cylinder rapidly recovers back and increases the discharge opening, so that the high-strength material is eventually discharged from the outlet. When the high-strength material is automatically discharged by its own weight, the hydraulic control system moves quickly to the hydraulic cylinder.Right cavity oil supply, so that the piston left to the limit position, return to normal operation.
