The maintenance and upkeep of the wet mixing granulator in the laboratory should be combined with daily cleaning, regular inspections, and preventive maintenance. The specific methods are as follows:
1、 Daily maintenance
1. Cleaning and maintenance
Immediately clean the inside and outside of the equipment after use, and thoroughly remove any residue to avoid clumping after drying.
Wipe the inner wall and casing of the pot with 75% alcohol to ensure no contamination.
Check the compressed air pressure (standard 0.6Pa) and airtightness, and adjust the abnormal air pressure valve.
2. Key component inspection
The flexibility of the rotation of the mixing blade and cutting blade needs to be checked daily, and any abnormalities should be repaired or replaced in a timely manner.
Verify whether the button switch indicator light, sealing ring (hood/discharge port), and discharge piston function properly.
2、 Regular maintenance
1. Monthly inspection
Worm gears, worm gears, bearings and other components need to be checked for wear. If they are not flexible or severely worn, they need to be corrected or replaced.
Lubricate the gearbox to the center line of the dipstick, tighten the chassis screws and add lubricating grease.
2. Half year maintenance
Replace the worn motor synchronous belt and adjust the tensioning mechanism.
Clean the dust in the distribution box and check the operation status of the frequency converter.
3、 Long term disuse maintenance
1. Thoroughly clean the oil and powder inside the host, wipe the body and cover it with a dust-proof cloth.
2. Check electrical components, instruments, and connectors, and replace aging or rusted parts.
4、 Operating standards and environmental requirements
1. Operators need to receive training and strictly follow the procedures to avoid human errors.
2. The equipment should be placed in a dry, non corrosive gas environment to avoid extreme temperature and humidity effects.
The above measures can extend the service life of the equipment and ensure the quality of granulation.
