Sticking to the frame of an organic fertilizer double axis mixer is a common problem in organic fertilizer production, reducing mixing efficiency and increasing cleaning burden. Solutions can be implemented by addressing raw materials, structure, and operation.

Controlling the moisture content of raw materials is crucial. The ideal moisture content for organic fertilizer mixing is 25%–40%. Excessive moisture easily leads to sticking and clumping. Add appropriate drying additives during batching, such as crushed straw, dried manure, and humic acid, to reduce overall moisture content. Avoid adding too much liquid material at once; use atomized spraying for bacterial solutions and nutrient solutions to prevent localized over-wetting.

Optimize the equipment structure to reduce adhesion at the source. Install wear-resistant, non-stick lining plates on the inner wall of the mixer; a smooth surface significantly reduces material adhesion. Install movable scrapers or blades next to the impellers to clean residue from the cylinder wall during operation, preventing material hardening. Adjust the impeller angle appropriately to ensure sufficient material agitation and prevent prolonged pressure on the sidewalls, while ensuring stable and synchronized twin-shaft speeds.

Standardized operation and regular cleaning are also important. Adhere to small, frequent, and continuous feeding to avoid overloading, which can cause material to stick to the walls. Before shutting down, stop feeding, run the machine unloaded for a few minutes to clean the cylinder walls using residual material, then disconnect the power and check. During breaks in fertilizer produciton machine operation, promptly clean any hardened lumps adhering to the machine walls to prevent them from accumulating. When the machine is to be shut down for an extended period, be sure to thoroughly clean the inner walls, blades, and shaft, and keep them dry.

If wall sticking is severe, a small vibratory motor or air hammer can be installed to periodically loosen the accumulated material. By combining moisture control, structural modifications, and standardized operation, wall sticking can be significantly reduced, mixing efficiency improved, maintenance costs lowered, and continuous organic fertilizer production ensured.
