Installation steps and operation requirements of 8 main components of cone crusher

Cone crusher is an important production equipment for the fine crushing process in mine crushing production. The performance of cone crusher has a lot to do with the correct installation and reasonable operation and maintenance of the equipment. This article shares the basic steps and operating practices for cone breaking installation.

1) The equipment is placed on the basis of construction.

2) The equipment must be embedded with anchor bolts in accordance with the basic diagram (according to the user's requirements, the anchor bolts can also be used instead of the embedded iron scheme):

3) Strict horizontality should be maintained when installing the underframe. Before installation, the corresponding position of the underframe vibration damping pad must be polished and leveled, and the basic level should be checked with a spirit level.

4) Maintaining the horizontality of the base can ensure the dynamic balance of the equipment, thereby effectively ensuring the reliability of the machine.

1) The bearing should be installed hot, and the axial position of the bearing relative to the drive shaft should be ensured when installing the drive shaft.

2) After the drive shaft is installed, check the axial movement.

3) When installing the gland and host pulley, etc., a layer of sealant must be applied to the flat contact surface and flat key surface.

4) Hydraulic device can be used for the disassembly of the pulley of the host machine.

1) The exciter component has three eccentric blocks. There are keys on the upper and lower eccentric blocks and the shaft sleeve. There are three sets of key grooves on the shaft sleeve. The key grooves of different position groups can be replaced to extend the service life of the sleeve.

2) There are multiple key grooves on the outside of the fan-shaped part of the three eccentric blocks. The long key fixes the middle eccentric block by the force of the upper and lower eccentric blocks. When in use, the relative position of the middle eccentric block and the upper and lower eccentric blocks can be changed according to needs to obtain Different breaking forces.

3) When loading and unloading the eccentric block, a small angle wedge iron can be used to expand the opening of the eccentric block a little to facilitate loading and unloading.

4) Use steel structure high-strength bolts to lock the eccentric block and sink the nut into the open slot on one side. If due to conditions, only other high-strength bolts can be used on site, the bolts must not be rotated 90 ° after sinking, otherwise a thin iron plate should be welded on any symmetrical sides of the nut so that the nut can be locked by the opening slot .

5) After tightening the nut to make the two planes of the opening parallel, when applying the pre-tightening force, tighten the nut again with a one-meter lengthening rod to a certain angle. After applying the pre-tightening force, lock the nut.

6) Install two lock plates, the lock plates are close to the eccentric block. If there is a gap between the upper surface and the upper surface of the axial keyway of the sleeve, a thin iron plate can be used to compensate the gap under the lock plate. Tighten the bolts and lock them.

1) In order to ensure uniform and close contact, the auxiliary supporting spherical tile should be scraped with the moving cone supporting steel tile, and the outer ring of the spherical tile should have 10 to 15 contact points per 25mm × 25mm, and the inner ring should have a small amount of ring. gap.

2) Place the shaker flat on the ground, with the moving cone support seated on it. Put the flange on the shaft sleeve. Install the cone sleeve and the snap ring to ensure that the snap ring fits into the circumferential keyway of the shaft sleeve and sinks. Inside the cone sleeve step (see Figure 2).

3) Slowly lift the starting cone support to make the exciter slightly off the ground. Tighten the 8 bolts on the flange one by one, repeatedly and symmetrically, and then lock the bolts in groups of two.

4) The correct installation of the auxiliary bearing spherical tile and the shaker is conducive to ensuring the reliability of the equipment work.

1) Remove the protective oil coating on the main shaft, spherical surface and cone surface.

2) Apply a layer of yellow dry oil to the surface of the main shaft and a layer of thin oil on the spherical and cone surfaces.

3) Wrap the spindle with thin plastic paper to prevent contamination.

4) Place the moving cone on the iron frame, weld two symmetrical rings on the outer surface of the moving cone lining, lift the moving cone lining and install it on the moving cone, and install the small lining, backing ring and cap nut ( Left-hand thread), then use a special wrench and sledgehammer to tighten the cap nut, and use a feeler gauge to check the clearance between the moving cone liner and the moving cone, so that the gap is almost zero and consistent around the circumference.

5) When assembling, start the cone part at the cap nut, and slowly put the moving cone main shaft slowly into the exciter component shaft sleeve. Make sure that the spherical surface of the moving cone is in contact with the spherical tile supported by the moving cone to avoid movement. The tapered tongue ring or the outer edge is overhead on the moving cone support and crushes the seal ring.

1) The adjusting ring components include hoppers, threaded rings and fixed cone liners. The quality of its installation can also affect the stability of the equipment operation, the crushing effect and the service life of the fixed cone liners.

2) The fixed cone liner and the threaded ring contact through the conical surface. When installing, place the positive cone liner, place the threaded ring on it, place the flange on the threaded ring, and clamp the retaining ring on the fixed cone liner. The outer ring of the neck, then tighten the bolts one by one, repeatedly and symmetrically, jack up the flange and jam the snap ring.

3) After installing the fixed cone liner, you can install components such as pressure iron, seal ring and hopper.

1) Determine the relative position of the locking structure and the support ring according to the positioning pin, screw in the adjustment ring, and adjust to the proper position to get the proper working discharge opening clearance.

2) Always ensure that the locking structure is parallel to the support ring, open the high-pressure pumping station, adjust the pressure to 13 MPa, and screw down the jack of the structure jack sequentially, repeatedly, and symmetrically until it is screwed to death.

3) Turn off the high-pressure pump and remove the remaining pressure of the high-pressure pump.

4) Because the locking structure is locked by a disc spring, the high-pressure pump cannot be opened during normal operation of the equipment.

1) The lubricating device is installed according to the assembly drawing provided by the company. The user needs to prepare the HG4-761-74 specification oil pipe and other parts required for installation by himself. The oil inlet hose must be able to withstand pressures> 10MPa.

2) The configuration of the lubrication device must ensure smooth lubrication oil return and oil return.

3) After the installation of the lubricating device is completed, a test of the lubricating device should be performed, and the lubrication system and control should be adjusted. If the lubrication system is found to be faulty, it must be disassembled and repaired.

4) It is also necessary to debug the temperature and pressure control system of the lubricating device. Check the reliability of the electrical contact pressure gauges and temperature gauges and the reliability of their connection with the electrical control cabinet by adjusting the pressure and temperature upper and lower pointers to ensure the equipment control system reliability.

Correct installation of the equipment is the basis for stable operation. Only by grasping the correct installation method, strengthening the professional maintenance of the cone crusher, and timely discovering and dealing with various problems existing in its operation, can the improvement of the performance of the cone crusher be achieved.
