Addressing the issue of material sticking and crusting inside organic fertilizer disk granualtor machines requires a comprehensive approach focusing on three key areas: raw material control, equipment modification, and operational standardization. Priority should be given to raw material regulation, specifically by maintaining the material's moisture content within the range of 28% to 32%. Excessive moisture promotes adhesion to the disc surface; therefore, incorporating additives such as straw powder or rice husk powder can help reduce viscosity. For highly viscous organic fertilizers—such as chicken manure—bentonite should be blended in to regulate viscosity, and the use of uncomposted raw materials must be strictly prohibited. Raw materials must undergo thorough pulverization and screening to remove hard lumps and impurities, thereby preventing localized material accumulation and wall-sticking.
Fertilizer making machine configuration should be optimized by installing anti-stick liners—made of materials such as polyurethane or Teflon—on the disc surface to enhance smoothness and minimize material adhesion. The disc-cleaning scrapers should be inspected and replaced regularly; their clearance must be finely adjusted to ensure close contact with the disc surface, thereby thoroughly scraping away any accumulated deposits at the bottom. The tilt angle of the disc should be appropriately adjusted to between 45° and 55° to ensure smooth material rolling and prevent stagnation or clumping.

On-site operations must be standardized by utilizing atomizing nozzles to apply water in small, frequent increments; direct flushing with large volumes of water—which causes localized oversaturation—is strictly prohibited. This process should be paired with variable-frequency, constant-speed feeding to prevent sudden surges in material input that could lead to excessive layer accumulation and disc-sticking. During production, periodic inspections should be conducted to promptly remove thin layers of accumulated material before they harden into thick, stubborn crusts. Furthermore, the disc surface must be thoroughly cleaned and maintained after every shutdown. If hard, stubborn crusts have already formed, operations must be halted to allow for manual scraping and grinding to remove them; simultaneously, any loose components should be inspected and tightened to ensure the disc operates smoothly, thereby providing a long-term solution to material-sticking issues.
