Jaw Crusher Is Mainly Used In Two Ways To Achieve The Risk Of Overload And The Adjustment Of The Discharge Port

jaw crusher

One way:It is to use a hydraulic hydraulic gyratory crusher, which is situated the main shaft of the piston in the hydraulic cylinder, the volume change under the plunger hydraulic oil can change the upper and lower cone crusher location, thus changing the row size of the discharge port.When overloaded, the spindle downward pressure, forcing the plunger into the hydraulic oil in the hydraulic system accumulator, broken cone ensuing decline to increased discharging port, with material into the crushing chamber of the non broken material (iron, wood, etc.) in order to achieve insurance.

Second way:It is the use of mechanical means, the upper end of the spindle is adjusting nut, rotation of the adjustment nut, cone crusher can be lowered or raised, so that the discharge port becomes larger or smaller, overloading, cut off the drive pulley on the insurance pin to effect insurance.

The upper and the lower movement of the jaw crusher can promote the discharging function, and the upper part of the jaw is larger than the lower part of the horizontal stroke, and the crushing efficiency is higher than that of the double elbow plate type. Its disadvantage is that the jaw plate wear faster, as well as the material will have a crush phenomenon and the energy consumption increased. In order to protect the important parts of the machine is not due to overload.

When the jaw crusher is overloaded, the conical shell is forced to be compressed by the spring so as to increase the self, so that the discharge port is enlarged, and the non broken material is discharged.The adjustment of the material discharging opening is carried out by adjusting the sleeve, and the adjusting sleeve which is fixed with the shell can drive the shell to rise or fall by the screw thread on the outer circle, in order to change the size of the discharge port. The insurance and adjustment method of hydraulic cycle crusher is the same as the hydraulic cone crusher.
