Hydraulic jaw crusher PEY series

stationary

PEY series jaw crusher has the overload protection, and the rated load can be set casually. It can choose the suitable material to crash and do not deal improper material, so the “iron block” problem does not occur. It can work constantly without stopping the machine. The single hydraulic cylinder can adjust the size of the discharge port, and also can discharge the improper material after unloading. It is different from the double hydraulic cylinders, and it will not cause jaw segregation that can damage the equipment. self-equipped with hydraulic cylinder, PLC control system, mainly used for crashing metallurgical residue. Working principle of overload protection device 1.The fix jaw not moving is fixed on the inner wall of the crusher. 2.The motor through the pulley drives the eccentric wheel, so as to drive the movable jaw plate to do the pendulum motion in order to crush the materials. 3.The hydraulic cylinder piston rod is connected with the liner, and hinged with the spring pull rod at the lower part of movable jaw plate, this arrangement can determine the size of the discharging port and the crushed granularity. When the materials whose strength is exceeding the specified value are sent in the crushing chamber, the cylinder piston will retract quickly to enlarge the discharge port in order to discharge the materials more strength. 4.After the materials of high strength are discharged automatically by their own weight, the hydraulic control system supplies immediately the oil to the right chamber of cylinder making the piston move left to the extreme position so to return the normal work.
