Technical characteristics of ultra-fine grinder and tips for daily maintenance
Ultra-fine grinders are now widely used in various industries. Next, we will learn about the technical characteristics of superfine grinders and the daily maintenance tips for superfine grinders.
[What are the characteristics of the current applied technology of the ultrafine grinder]
1. It is small and beautiful, light in weight, and can be moved arbitrarily; it has the characteristics of simple operation, no vibration, low noise, power saving and safety, etc., especially suitable for research institutes, laboratory sample analysis, etc.
2. Ultra-high-speed motor design, vibrating ultra-fine grinding machine for medicinal materials with high crushing fineness (most medicinal materials are crushed with a fineness of 50-300 mesh); wide grinding range: Panax notoginseng, Sanqi, frankincense, myrrh, donkey-hide gelatin, dodder, Hippocampus, astragalus, etc. can grind well.
3. The speed is fast, and the grinding time of the vibrating ultrafine grinding machine is generally no more than 3 minutes.
4. It is clean and hygienic, and does not raise dust when working. The grinding groove and blade of the vibrating ultra-fine grinder are made of stainless steel, which meets the iron-free requirements of many Chinese medicines.
5. There is basically no loss of materials, and the machine is easy to clean; grinding different medicines will never cross the color and smell.
6. The operation is simple, and the personnel do not need special training.
7. The structure is durable and economical. The blade is made of special steel, which is of the same quality as the razor, and there is no need to change the knife to crush 100-200kg pieces.
[Tips for daily maintenance of superfine grinder]
1. When the bearing oil temperature rises, you must stop immediately to check the cause of the fault and eliminate it.
2. Pay attention to the degree of wear of the parts that are easy to wear, pay attention to and prepare to replace the worn parts at any time.
3. For the surface of the bottom frame where the movable device is placed, it is necessary to remove dust and other debris to avoid the phenomenon that the movable bearing cannot move on the bottom frame when the machine encounters materials that cannot be crushed, which may lead to accidents.
4. The bearing that bears all the load of the machine is the bearing, so good lubrication has a great relationship with the service life of the bearing. It can directly affect the service life and operation rate of the machine. Therefore, the cleanliness of the injected lubricating oil must meet the standard and the seal is good.
5. The installed wheel tyres are prone to looseness and must be checked frequently.
6. Pay attention to whether the working conditions of each part of the machine are normal.
7. If the rotating gear is running, if there is an impact sound, it must be stopped in time for inspection and the malfunction should be eliminated.
The principle of daily maintenance of ball mill
Ball mills can play a greater role in industrial production only after good daily maintenance.
1. All lubricating oil should be discharged when the mill is put into continuous operation for one month, thoroughly cleaned, and replaced with new oil. In the future, the oil change will be carried out approximately every 6 months in conjunction with the middle repair.
2. The lubrication condition and oil level of each lubrication point are checked at least every 4 hours.
3. When the mill is running, the temperature of the main bearing lubricating oil should be lower than 55°C.
4. When the mill is running normally, the temperature rise of the transmission bearing and reducer should not exceed 60℃, and the high temperature should be lower than 70℃.
5. The large and small gears drive smoothly without abnormal noise.
6. The ball mill runs smoothly without strong vibration.
7. Check the motor current from time to time for no abnormal fluctuations.
8. During routine maintenance, ensure that the connecting fasteners are not loose, and there is no oil leakage or water leakage on the joint surface.
9. The wear condition of the steel ball should be added in time.
10. If an abnormal situation is found, the grinding should be stopped immediately for maintenance.
11. The mill liner should be replaced when it is 70% worn or there are 70mm long cracks.
12. When the liner bolts are damaged and the liner becomes loose, replace it.
13. Check that the main bearing should be replaced when it is severely worn.
These maintenance principles seem cumbersome, but in fact the operation is very simple. As long as the production of the ball mill is treated seriously and carefully, and the daily maintenance is done, the economic benefits that the ball mill can bring will be huge.
