Update and maintenance of cone crusher accessories

Cone crusher accessories include broken walls, rolled walls, bowl bearings, and copper sleeves. How to replace the cone crusher accessories, we will come to you for details.

How to update the cone crusher accessories:

1. The cylindrical bushing and the frame are the third transition fit. In order to prevent the rotation of the bushing, the zinc alloy is injected into the upper groove of the bushing. When replacing the new bushing, it should be prepared according to the actual size of the frame, because The long-term work and loading and unloading of the crusher through the vertical crusher will inevitably lead to a change in the coordination relationship. If the gap is too large, the bushing will be broken.

2. Conical bushing, taper sleeve and empty eccentric shaft should be strictly combined, zinc alloy should be injected to prevent rotation of the taper sleeve, zinc alloy should be filled with all gaps, due to the price of hot-zinc-zinc alloy crusher, it may cause taper sleeve stone production line. Deformation, so the new cone is set to check the size. If it is found to be incorrect, it should be corrected in time. The spare parts should be prepared according to the actual size of the inner diameter of the eccentric sleeve to maintain the original fit.

3. Spring, the role of the spring is to protect the crusher from damage when the crusher enters the unbreakable material, so the pressure of the spring is compatible with the crushing force of the crusher. The spring is not moving during normal operation, only the spring When the iron block is dropped into the crushing chamber and the crusher is overloaded, the spring is compressed when the bearing sleeve is lifted. The upper part of the cone crusher jumps during normal operation. This is an abnormal phenomenon. The sand making equipment must be carefully analyzed. The reason is to take measures to eliminate it. If the spring is incorrectly compressed, it will not work properly, but the parts may be damaged. The compression spring will cause an increase in the crushing force.

Cone crusher maintenance

Since the main component of the cone crusher is steel, it is very easy to rust. The machine after rusting will affect the normal operation and cause economic loss. Therefore, it is the key to reasonable maintenance and storage:

  • 1. If the flywheel has been removed from the eccentric shaft, the contact surface between the flywheel and the shaft should be coated with a preservative.
  • 2. Allow the crusher to operate at least once a month during storage of the cone crusher or during seasonal shutdown to ensure that the bearings remain properly lubricated. If the crusher cannot be operated during storage, the crusher flywheel must be manually rotated 3 to 4 times to ensure that the bearings are properly lubricated. Add grease to the bearings if needed.
  • 3. If the moving body has been removed from the frame, in order to prevent debris from entering the bearing seat, sufficient grease should be applied in the seal. The bearing housing contact surfaces on the frame and the frame, bracket contact and bracket seat contact surfaces, and tie rod holes (if applicable) should also be coated with a preservative.
  • 4. When the cone crusher is taken out from the storage, the paint must be inspected and repaired as needed. The preservative should be removed from all contact surfaces before assembling the crusher.
  • 5. The cone crusher and its removed parts should be stored on a stable bracket to prevent contact with the ground.

After the user purchases the cone crusher, in order to ensure the production life and the efficiency of the operation, the equipment is tested at intervals. So what are the testing tasks of the cone crusher?

  • 1. The general inspection time is started after the equipment is finished, and after five or six hours of cooling.
  • 2. The inspector firstly checks the flatness of the surface of the conical surface to see if there is any unevenness. If so, inform the technician to carry out the transformation.
  • 3. It is found that unqualified parts or parts with deviations should be replaced in time.
  • 4. For the operation of the empty machine with broken cone, before starting the machine, check whether the equipment is installed well. Everything is normal and can be turned on. During the empty operation, it is necessary to check the sealing, jamming, friction and impact of the equipment. And other issues.
  • 5. During the test run, check whether the cylinder body has obvious sway, whether there is too much noise, ensure that the cylinder shakes no more than 0.5mm, and the noise is controlled within 85db.
  • 6. After the cone is put into formal work, the staff needs to insert the special thermometer for the rolling bearing into the oil control of the bearing seat, and measure it once every hour, knowing that the temperature is stable.
