Causes and preventive measures of the fracture of the cone crusher

Cone crusher has a wide range of applications in mining, metallurgy, chemical, coal and other industries. During its operation, spindle breakage is a common fault that can seriously affect the normal operation of the crusher. Therefore, effective measures must be taken to avoid the occurrence of this failure.

There are three reasons for the fracture of the cone crusher spindle:
1. Due to the * working characteristics of the crusher, the spindle suffers from frequent mechanical shocks and fatigue damage.
2. Too much feed, causing the equipment to run overload.
3. During the mining and transportation process, the ore is often mixed with some waste metal materials. When these objects pass through the electromagnets at the upper end of the tape, the electromagnet cannot be removed due to the weak adsorption capacity of the electromagnet and the metal characteristics of the manganese-containing steel material. These materials are mixed into the crusher in the ore and mud, causing frequent iron, which causes frequent impact on components such as the main shaft. The main cause of fatigue damage is the main shaft fracture.

Precaution:
1. When the on-site maintenance personnel perform maintenance work, the replaced parts should be recycled and placed in the designated location. It is strictly forbidden to discard all kinds of metal waste into the ore.
2. When the maintenance personnel in the ore dressing workshop are not ready for maintenance, strictly observe the operating procedures and avoid leaving the maintenance tools and debris in the equipment.
3. Through the procurement and relying on its own technical strength, the existing metal detectors are updated or modified to improve the ability of metal detectors to detect and exclude metals.
4. The operator who cares for the feeding tape of the crusher should strengthen the sense of responsibility, increase the inspection intensity of the materials, and find that the foreign objects should be sorted out in time.
5. The crusher operator will not be ready for inspection in time, and find that abnormal conditions such as current and sound should be handled and reported in time to prevent accidents from expanding.
6. Regularly use ultrasonic instruments to inspect the components such as the spindle to understand the actual condition of the equipment.
7. Strengthen the training of operators in each section, strive to improve the actual operation level of the operators, strengthen the maintenance of equipment, and ensure that the equipment is in a good technical state in time for the large and medium repairs of the equipment.
8. For the spindle, body and other key equipment components that can affect the production of the whole system, do a good job in the procurement of spare parts for inventory, so as to avoid the special system to s* production after the occurrence of special circumstances.
