Features
Cone Crusher is an advanced hydraulic crusher with high power, high crushing ratio and high productivity. Cone breaking is suitable for fine and ultrafine crushing of hard rock, ore, slag, refractory materials, etc. As an important equipment in the mining crushing industry, cone crusher has brought great economic benefits to customers. However, in actual operation, many users have found that their crushers frequently appear dead phenomenon, can not work normally, seriously delay the subsequent processing. Here is a brief introduction to why the cone crusher suddenly embrace the three reasons, I hope to help you.
Cone crusher
1. Improper amount of lubricating oil is added
When lubricating, the amount of lubricating oil added is too large to increase the friction torque, and the amount of lubricating oil is too small to achieve the lubrication effect, in addition, the lubricating oil containing impurities, failure or does not meet the needs of the equipment will also make the cone crusher equipment can not get good lubrication effect.
2, blocked material or difficult to break into the material
Cone crusher feed too much, or feed characteristics do not meet the requirements, will lead to the cone crusher clog the material, so that the crusher working current is too large, the circuit automatic protection stop, and even the cone crusher may be forced to stop.
In addition, when the crusher enters the iron, because the iron parts are hard, the good press is broken, it will be stuck between the moving and fixed cone liner, the pressure increases instantaneously at the moment of breaking, and the power also increases. This process will constitute excessive wear of the vulnerable parts, bushing deformation, and the occurrence of safe shaft holding.
3. The main shaft is broken
There are two causes of spindle breakage. First, the structure is unreasonable. When the interference of the spindle and the moving cone mating surface is relatively large, or there is no unloading groove, the stress concentration of the spindle will be generated, the bearing capacity is too large, the spindle fatigue will occur, and then lead to damage. In addition, when the spindle is relatively small in design, it is easy to have the problem of "over-iron", which leads to fracture; Second, the manufacturing quality is not up to standard. In the manufacturing process of the spindle, the heat treatment work is not well done, the material is general, which reduces the compression resistance of the spindle, and once it encounters unbreakable objects, it is easy to have the problem of the spindle breaking. In addition, there are problems such as lubrication, over-iron overload, and equipment aging, which are also one of the reasons why the spindle may break.
