It’s essential to understand and implement effective daily maintenance and care measures to extend equipment life and prevent potential issues. By following these practices, you can avoid common problems and minimize the need for fluid bed granulation troubleshooting.
In this article, fluid bed granulator manufacturers Canaan will introduce in detail the daily maintenance and care methods to help you ensure the optimal performance of the equipment.
| Maintenance Step | Description | Frequency |
| Regular Cleaning | Clean all parts, including the heater, fan, container, drying room, cylinder, and control cabinet. | Regularly |
| Oil Mist Check | Check oil mist in the air handler; add 5# or 7# mechanical oil to maintain two-thirds oil volume. | Regularly |
| Lubrication of Bearings | Clean and lubricate support bearings with 5-8 drops of oil. | Daily |
| Start Equipment Regularly | Run the granulator for 20 minutes every 15 days, even if not in use. | Every 15 Days |
| Thorough Component Cleaning | Clean the raw material container, spray drying chamber, filter bag rack, and airflow distribution plate. | Regularly |
| Bag Maintenance | Replace damaged or inefficient filter bags to maintain drying performance. | As Needed |
| Wire Rope Tension | Loosen wire rope to prevent stress and potential breakage. | After Installation |
| Control Airbag Pressure | Ensure airbag inflation pressure is between 0.05-0.1 MPa. | Regularly |
| Shaking Bag for Dust Removal | Shake the bag to remove dust before discharging; clean the material temperature sensor. | Before Discharging |
| Ground Wire Setup | Connect the ground wire before operation to ensure safety. | Before Each Use |
| Material Loading Limit | Ensure wet material does not exceed 200 kg to prevent overloading. | Each Use |
Regularly clean all fluid bed granulator parts, including the heater, fan, container, inside and outside of the drying room, cylinder, control cabinet, and any other components to keep the equipment clean. This helps prevent dust and dirt buildup, which could affect performance and efficiency.
Regularly check the oil mist of the air inlet source (air handler). Add the appropriate amount of 5# or 7# mechanical oil (transformer oil) to the oil cylinder on the air outlet side of the air handler. Ensure the oil volume is two-thirds of the total oil mist. If there’s water in the water filter, be sure to discharge it promptly to maintain optimal function.
The support bearing of the spray drying chamber should rotate flexibly. The rotating part should be cleaned and 5-8 drops of lubricating oil should be dripped into it every day.
Even when not in use, it’s important to start the fuid bed granulator every 15 days for a minimum of 20 minutes. This practice helps prevent the solenoid valve and cylinder from drying out due to long-term inactivity, which could cause damage. Regular operation ensures the longevity of parts such as the solenoid valve and cylinder.
Regularly pull out the raw material container and spray drying chamber for cleaning. Remove the filter bag rack and capture bag, close the damper, and clean all materials left in the system, especially the gaps on the air flow distribution plate in the raw material container. Timely cleaning and drying of the cloth bags is also essential to maintain efficient operation.
If the filter bag is leaking or damaged, or if the drying efficiency is low, replace the bag promptly. Proper maintenance of fluid bed dryer filter bags is key to sustaining performance and efficiency in the drying process.
After installing the filter bag, make sure the wire rope is loosened to avoid stress and prevent it from breaking, which could damage the cylinder or other components of the fluid bed dryer.
Control the airbag inflation pressure to 0.05-0.1MPa. Too much pressure will damage the airbag.
Shake the bag to clean the dust before discharging, and remove the material temperature sensor.
Set up the ground wire before starting the fluid bed dryer. Proper grounding ensures safety and optimal performance during the operation.
To prevent overloading, ensure that the total amount of wet material loaded into the fluid bed dryer each time is under 200 kg. This helps maintain the dryer’s efficiency and prevents malfunction.
By following these daily maintenance steps, you can keep your fluid bed dryer running efficiently and reduce the risk of costly repairs. For any issues, refer to fluid bed granulation troubleshooting resources, or consult with fluid bed granulator manufacturers for additional support.
