Cone crusher shaft fracture

2021 - cone crusher shaft fracture 01 - 24 cone crusher in mine, metallurgy, chemical industry, coal and other industries have a wide range of applications. In the process of their work, the main shaft fracture is a common fault, the fault serious will cause the whole production line shutdown. So to take effective measures to prevent the occurrence of the fault. The main reason for the main shaft fracture 1) Because the crusher working characteristics, long withstand frequent mechanical shock, main shaft fatigue damage is produced. 2) Feeding too much, cause equipment overload operation. 3) Minerals in the mining transport process, often involving some scrap metal, these objects through setting the electromagnet, tape the top because of the electromagnet adsorption ability is weak, and characteristics of metal containing manganese steel materials, electromagnet could not be ruled out, these materials mixed in the mineral and the mud into the crusher, iron is frequent, caused the frequent impact of main shaft and other parts. Make the spindle produces fatigue damage, is a major cause of shaft fracture. Preventive measures 1) On-site maintenance personnel in maintenance work, dealing with the cone crusher replace down recycling scrap parts, in the specified location, it is strictly prohibited to will all kinds of metal waste disposed of in the ore. 2) Ore dressing workshop maintenance personnel maintenance equipment, strictly abide by the operation procedures and avoid maintenance tools and debris left in the equipment. 3) By purchasing and rely on its own technical force, to update or modification of existing metal detector, improve the ability of metal detector to detect and eliminate the metal. 4) Guards crusher feed tape operators should strengthen the sense of responsibility, increase its tour of the material, found that foreign bodies to pick out in a timely manner. 5) Jaw crusher operators of equipment checks in place in time, found that the current, noise and other abnormal situation should be handled in a timely manner, report, prevent accident expanding. 6) Regular use of ultrasonic flaw detection equipment for the main shaft bearing components, such as to understand the current actual situation of the jaw broken equipment. 7) To strengthen the training of each section of operators, and strive to improve the level of operators in practice, strengthen the equipment maintenance and repairing of equipment of large, be in place in time, ensure the equipment in good technical condition. 8) For the main shaft, the focus of the body and the other can affect the whole system production equipment parts, to do a good job of purchasing the inventory of spare parts, so as not to appear special circumstances after the production of the whole system.
