The fertilizer granulator is a core piece of equipment in a fertilizer production line. Its operating condition directly impacts the quality and production efficiency of the fertilizer granules. Proper machine maintenance not only reduces downtime, but also extends equipment life and reduces production costs. The following describes key points for fertilizer granulator maintenance, focusing on daily, periodic, and special maintenance.

Daily maintenance should be performed after daily operation, focusing on "cleaning" and "inspection." First, remove any residual fertilizer granules and dust from the machine, especially the granulation chamber, conveyor belt, and screening unit. Cleaning should be performed with the power off and using a soft brush or compressed air gun. Next, check the tightness of key components, such as the granulator's main shaft bolts and motor terminals, to prevent loosening and vibration noise. Also, check the lubricant level to ensure adequate lubrication of the transmission system (such as gears and bearings). If the oil is cloudy, replace it promptly.
Regular maintenance is recommended monthly, focusing on "in-depth inspection" and "component maintenance." The bearing caps should be removed to inspect the bearings for wear. If scratches, unusual noises, or excessive play are detected, replace the bearings with the same model immediately. Check the aperture and surface smoothness of the pelletizing die. If the aperture is clogged or the surface is worn, clear and polish it with specialized tools. In severe cases, replace the die with a new one. Additionally, the motor belt should be adjusted for tightness. Too loose will reduce transmission efficiency, while too tight can easily cause the belt to break. Adequate tension should be maintained until the belt sinks 1-2 cm when pressed.
Maintenance in special circumstances cannot be neglected. If the machine is out of service for an extended period (more than one month), thoroughly clean the inside and outside of the machine, apply anti-rust oil to metal surfaces, and cover the entire machine with a dust cover. If the production environment is humid or dusty, increase maintenance frequency. Check the electrical control system weekly for moisture and dust protection to prevent short circuits.
In short, fertilizer granulator machine maintenance should adhere to the principle of "prevention first, timely maintenance." Through standardized maintenance procedures, the equipment will always be in good operating condition, providing stable support for fertilizer production.
