In the fertilizer and chemical industry, the Disc Granulator is a key equipment, and its daily inspection and maintenance is essential to ensure production efficiency and product quality. The following is combined with the maintenance experience of other related equipment (such as mixers and screening equipment) to further elaborate the maintenance points of disc granulator. By combining the maintenance experience of the disc granulator , horizontal mixer, drum screener and other equipment, the maintenance process of the disc granulator can be more systematically understood and optimized to ensure its long-term stable operation and improve production efficiency.





5.1 Routine check and maintenance items

Regular inspection of bearings and gears

The bearings and gears of the disc granulator are the core components of its power transmission and need to be checked frequently. Similar to the maintenance of Horizontal Mixer, check the operating condition of bearings and gears at least once a week, including temperature, vibration and noise. Monitor the bearing temperature through the temperature measuring gun to ensure that it is within the normal range; Check gear meshing and oil quality, avoid oil pollution, and replace gear oil regularly to ensure long-term stable operation of equipment.

Cleaning and lubrication

Keep the disc granulator and its surrounding environment clean, regularly clean the dust, oil and debris on the equipment, especially the transmission parts and lubrication system, to prevent blockage and corrosion. In terms of lubrication, it is necessary to lubricate each lubrication point regularly according to the requirements of the equipment manual, similar to the maintenance of the Drum Screener, to ensure that the components are well lubricated and reduce wear.

5.2 Fault Diagnosis and Troubleshooting

Common faults and troubleshooting

1. The disc does not turn or rotates unsmoothly:

Similar to the fault handling of Chain Crusher or Single Axis Urea Crusher , check whether the motor and transmission are normal, clean up excessive materials in the disc to avoid overload.

2. Excessive noise:

Similar to the maintenance of a Ball Shaping Machine or Hydraulic Type Roller Granulator, check the wear of bearings and gears, tighten loose parts, adjust gear clearance, and ensure smooth engagement.

3. The material is not granulated or the granulation effect is poor:

Combined with the debugging experience of the New Type Organic Fertilizer Granulator or the Ring Die Granulator, the ratio of raw materials, moisture content and the rotation speed and Angle of the disc are adjusted to optimize the granulation effect.

Emergency treatment and prevention
When the fault is found, it should be stopped immediately for inspection to avoid the expansion of the fault. For simple faults, such as loose fasteners, can be repaired on site; For complex faults, contact professional maintenance personnel. In terms of prevention, the daily inspection and maintenance of equipment should be strengthened, operators should be regularly trained to improve their fault judgment ability, and equipment operating procedures and maintenance plans should be strictly implemented.
