What is the cause of the left and right swing of the crankshaft?
The jaw crusher operator is not ready to check in place in time, found that the current, sound and other abnormal circumstances should be promptly dealt with and reported to prevent accidents to expand.
1) due to the special working characteristics of the crusher, long time to withstand frequent mechanical impact, spindle fatigue damage.2) excessive feeding, resulting in equipment overload operation.3) ore mining in the transport process, often with some scrap metal, electromagnet these objects set through the upper end of the tape, because the electromagnet adsorption capacity is weak, the characteristics of metal containing manganese material plus the electromagnet cannot be excluded, resulting in these materials mixed in the ore and mud into the crusher, resulting in frequent iron thus, resulting in frequent impact on the main axis.
Preventive measures:1) on-site maintenance personnel in the maintenance operation, should be replaced by the cone crusher scrap parts recycling, placed in the designated location, is strictly prohibited to scrap all kinds of metal waste into the ore at will.2) the maintenance staff in the dressing workshop shall strictly observe the operating rules and avoid the maintenance tools and sundries left in the equipment when they are overhauling the equipment.3) by purchasing and relying on their own technical power, the existing metal detectors can be updated or modified to improve the capability of metal detectors to detect and eliminate metals.4) feed belt guard crusher operator to strengthen the sense of responsibility, increase the material inspection efforts, found out the foreign body should be timely.
