The new type two in one organic fertilizer granualtor integrates granulation and screening functions. The screen, constantly in contact with high-moisture organic matter and coarse fibrous materials, is prone to clogging, material adhesion, wear, and deformation. Scientific maintenance can extend its service life and stabilize screening results.

Daily pre-shift and post-shift cleaning is essential. After each shift, use a soft brush and high-pressure air gun to thoroughly clean the powder, wet material, and fibrous debris adhering to the screen holes to prevent material from drying and solidifying, causing permanent clogging. Never use sharp iron objects to scrape or pry forcefully to prevent scratching or puncturing the screen. If the material has high moisture content and the screen is heavily adhered to, gently rinse it with clean water periodically, and then thoroughly dry it before restarting the machine to prevent rust.

During operation, manage the working conditions carefully. Before feeding, try to remove stones, hard metal blocks, and other impurities to reduce impact and collision with the screen. Control the moisture content of the raw materials within the process standard range; excessive wet material will significantly increase the load on the screen. Observe the operating status of fertilizer production machine. If loose or misaligned screens are found, tighten the pressure bars and clips promptly to prevent deformation and cracking caused by impact and friction during operation. Stop the machine for repair if abnormal vibration occurs to avoid resonance that exacerbates screen wear.

Conduct regular in-depth inspections and maintenance. Check the screen surface daily for wear, broken wires, and cracks. Repair small damage promptly, and replace larger damaged areas immediately. Inspect the screen frame and supporting ribs for deformation to ensure even stress distribution. Regularly adjust the tension of woven screens; too loose and they will shake and break, too tight and they will accelerate fatigue and aging. For perforated screen plates, pay special attention to the welds and edges; repair and reinforce any detached welds promptly.

When the machine is shut down for an extended period, thoroughly clean away any residual material, disassemble and dry the screens, and store them in a dry, ventilated place to prevent moisture, rust, and sun aging. Proper maintenance combined with appropriate equipment selection can effectively reduce the frequency of parts replacement and ensure continuous and stable operation of the production line.
