Gyratory Crusher

Gyratory Crusher Description:

Gyratory Crusher is the metallurgy, building materials, chemicals and water and electricity sectors for crushing ore or rock is one of the main equipment, our company design and manufacture of Gyratory Crusher more than 30 years of history, its products from PXZ 0506 series has been formed to PXZ 1623 . I produced the gyratory crusher has PXZ (heavy), PXQ (light) and PXF (introduction) three series, which PXZ Series for crushing medium or above medium hardness of various materials; PXQ series for crushing medium or medium the following hardness of various materials; PXF series for large open pit mine and concentrator.

Gyratory Crusher structure

Gyratory Crusher from the drive, chassis, eccentric, crushing cone, the body frame, beams, mover, cylinder, hydraulic, pulleys, electrical and dry, thin lubricating components. Motor pulley and bevel gear driven by the eccentric sleeve rotation, the eccentric sleeve rotates when you drive around the broken crusher Center for the Swing movement. So that the cone surface from broken out near the fixed cone surface from time to time, so to keep the material into the crushing chamber by squeezing and bending effects have been broken.

Gyratory crusher working principle

Is the use of cone crushing cone within the shell cavity of the cyclic movement of materials produced extrusion, splitting and bending, crushing of rock hardness of the ore or large crushing machinery. Broken cone beam axis of the upper bearing in the middle of the bush, the eccentric sleeve is placed on the bottom of the hole. Sleeve rotates, around the broken cone machine centerline as eccentric cycle exercise its crushing action is continuous, so the efficiency is higher than jaw crusher. To the early 1970s, large gyratory crusher has been able to handle material per hour, 5000 tons, the maximum diameter of feeding up to 2,000 mm.Cycle crusher two ways to achieve nesting population adjustment and overload insurance: First, the use of mechanical means, the spindle nut to adjust the top, rotate adjusting nut, cone crusher can be decreased or increased, the discharge port along larger or smaller, overloaded, by cutting off the pin on the drive pulley to achieve insurance; the second way is the use of hydraulic breakers hydraulic cycle, the spindle is located in the hydraulic cylinder of the plunger, change under the plunger hydraulic oil can change the volume up and down the crushing cone position, thus changing the nesting population size. Overload, the spindle downward pressure, forcing the plunger into the hydraulic oil in the accumulator hydraulic system, so broken cone fall in order to increase the discharge opening, discharge material into the crushing chamber with a non-broken materials (iron, wood, etc.) in order to achieve insurance.

Gyratory crusher installation and maintenance

Machine maintenance is an extremely important regular work, it should be extremely closely with the operations and maintenance, etc., should be full-time staff on duty checks.
I. Installation test:
1, the device should be installed on a level concrete foundation with anchor bolts.
2, the installation should pay attention to the level of the host body and the vertical.
3, various parts of the installation check for loose bolts are tightened and doors of the host, where do the tightening.
4, according to the device's power cord and control switch configuration.
5, the inspection is completed, the empty load test, you can test the normal production.
II. Machine maintenance:
1, all load bearing shoulder of the machine, so good lubrication of the bearing life of a great relationship, it directly affects the life of the machine and the operation rate, which requires injection of the oil must be clean, seal must be good, the machine main oiling Office
(1) Turn the bearing
(2) roller bearings
(3) All gear
(4) activities bearing, sliding plane.
2, the newly installed tires prone to loosening must always be checked.
3, note that the various parts of the machine is working properly.
4, pay attention to check the wear parts and the replacement of worn parts.
5, put the event the device chassis plane should remove dust and other objects in order to avoid the machine when the material could not have broken the bottom shelf in the activities of the bearing cant move, resulting in a serious accident.
6, the bearing temperature rise, the reasons should be immediately stopped and checked to be eliminated.
7, turn the gear when in operation should be immediately stopped if the impact of the sound check, and remove.
