Shandong airflow crusher manufacturer's main shaft fracture reasons and solutions
The core parts of the mill are wear rollers, milling, and assembly, and these accessories are also easy, once they don't pay attention Overhaul will cause serious consequences, especially the breakage of the spindle will result in discontinuation, and the loss of production is not estimated; if the spindle is at work time, the first threats of staff security issues. What is the reason for the spindle break?
1, due to the characteristics of the working mill, long crushing, grinding pieces of rock, the mechanical impact causes frequently spindle fatigue damage.
2, excessive feedstock causing oversight operation of the mill.
3, ores during mining transportation, often sandwiched some waste metal, these objects are provided by electromagnets in the upper end of the tape, due to the weak adsorption capacity of the electromagnet, and the metal characteristics of manganese-containing steel material Electromagnet cannot be excluded, causing these materials inclusions in ore and mud into the mill, resulting in frequent iron, thus causing frequent impact on the spindle. It is the main reason for the spindle to produce fatigue damage.
Xiaobian summarizes the reason for the spindle break, do we know if you want to prevent this malignant accident?
1. On-site maintenance personnel respond to the replacement of abandoned components in the maintenance operation, put it into the designated position, which is strictly prohibited to discard all kinds of metal waste casually into the ore.
2, the maintenance staff of the mine workshop is not prepared, strictly abide by the operating procedures, avoiding the maintenance tools and debris remain in the equipment.
3, through procurement and relying on its own technical force, the existing metal detector is updated or transformed, and the metal detector detection and the ability to exclude metal.
4, watching the crusher feed tapeThe work should strengthen the sense of responsibility, increase the inspection of the material, and find foreign objects to pick out in time.
5, the milling of the milling equipment operator is in time in time, discovery current, sound and other abnormalities should be dealt with, report, and prevent accidents.
6, regularly utilizing ultrasonic waves and other instruments to detect the power components such as the main shaft to understand the actual situation of the current equipment.
7. Strengthen training for operating workers in various units, and strive to improve the actual operation level of operators, strengthen equipment maintenance, to ensure the large-scale in place for equipment, and ensure that the equipment is in good technical state.
8. For the main shaft, the body, and other key equipment components that can affect the production of the entire system, the procurement of their stock spare parts is made to avoid malfunction of the entire system after special circumstances.
