Planetary ball mills used in laboratories are divided into gear transmission and belt transmission. For gear transmission ball mills, there are some fault phenomena that we often encounter when using the instrument.
Next, Kingda Ceramic will summarize the gear transmission. Several fault strike phenomena of transmission planetary ball mill and common maintenance methods.
Failure phenomena of gear transmission planetary ball mill
1. The main bearing vibrates violently and works unstable;
2. The main bearing temperature exceeds 65°C and continues to rise;
3. Part of the internal transmission gear of the planetary ball mill falls off or the teeth are broken;
4. The lubrication system fails and the movement resistance of the instrument increases;
5. The instrument suddenly loses power during operation, causing mechanical damage;
6. The connecting bolts such as lining plates, manhole covers, rotating parts, etc. are loose or broken;
7. The internal reducer and electric motor are abnormal and cannot operate normally.
Maintenance methods of gear transmission planetary ball mill
1. Keep the surface of the instrument clean and the cavity free of dust pollution. Pay attention to regularly checking whether the lubricating oil or grease is sufficient, and pay attention to checking the sealing of the whole machine. Industrial gear oil is generally used as lubricating oil at room temperature.
2. The lubricating oil of the reducer should be replaced for the first time after 300 to 600 hours of initial operation. During replacement, residual oil stains should be removed. From now on, the oil should be changed every 1500 to 5000 hours, but the oil change interval should not exceed 18 months.
3. Pay attention to the observation of each instrument. If there is any abnormality, stop it in time to eliminate it. If the cause is not found and the fault is not eliminated, the operation should be stopped.
4. Operators should receive relevant operating training and fully understand the structure and performance of the machine. Before operating the machine, read the instruction manual and operate according to the instructions.
5. Pay attention to the workload during the running-in period. The workload during the running-in period should generally not exceed 80% of the rated workload, and an appropriate workload must be deployed to prevent overheating caused by long-term continuous operation of the machine.
The above are several common fault phenomena and related maintenance methods of gear-driven planetary ball mills. From the above, it can be seen that gear-driven planetary ball mills have problems such as broken teeth, heat, and noise due to the influence of mechanical structure and transmission. There is no good solution. To fundamentally solve these problems, it is necessary to purchase a planetary ball mill using belt transmission as soon as possible.
