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.
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.
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:
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?
