Working principle of hydraulic gyratory crusher

When the hydraulic cylinder is lifted by pressure, the shaft pin is first cut off and the crusher stops running, thus saving other parts of the machine from damage.

When a large non-crusher enters the crushing chamber, the large bevel gear with three thrust discs set on the eccentric shaft sleeve rotates, thus making the dynamic cone swing.

In addition, the large bevel gear and the central sleeve, so that the direction of rotation of the movable cone is opposite to the direction of rotation of the eccentric shaft sleeve.

This rotation movement makes the crushing product size more uniform and makes the movable cone liner wear evenly. The movable cone generates a frictional moment M due to the crushing force.

Because of the friction force F>F (friction coefficient fa>the friction moment M on the main shaft can make the movable cone rotate around its own axis, and its direction is the same as the direction of rotation of the eccentric sleeve.

When the crusher is running at no load, the hydraulic gyratory crusher differs from the above-mentioned gyratory crusher in that: the hydraulic cylinder is installed at the support ring of the main shaft suspension point, the quality of the moving cone is made inside the shaft sleeve, and the dustproof device is installed at the bottom of the moving cone.

The conical nut is used as an adjustment device. Turning the conical nut, the spindle and the movable cone rise or fall, so as to adjust the size of the discharge opening to crush the material.

At the same time, the crushed material moves downward under its own weight until it is discharged from the discharge opening. In order to prevent the dust from falling into the eccentric sleeve when discharging, a dustproof device is added. When the eccentric sleeve rotates, the main shaft of the movable cone makes cone movement with the cone apex as the suspension point on the cross beam, and the role of the transmission mechanism is to transmit power.

When the motor rotates, the centerline of the hole is slightly eccentric to the axis of the gyratory crusher through the v-belt pulley, the coupling, and the small bevel gear. The inner and outer surface of the eccentric bushing are cast (or fusion welded) a layer of pasteurized alloy, the outer rely to ensure that the bushing along the support ring and conical bushing rolling, to meet the requirements of the main shaft movement. The lower end of the spindle is inserted into the eccentric hole of the eccentric bushing, and the whole mass of the spindle and movable cone is supported by the tapered bearing in the cross beam.
