The mixing time of a organic fertilizer double axis mixers directly affects mixing uniformity, production capacity, energy consumption, and material properties. Control should adhere to the principles of uniformity without waste and short mixing time to avoid undermixing.

First, determine the basic mixing time based on the material's state. For powdery, dry organic fertilizers with simple proportions, a mixing time of 2-4 minutes is suitable; for fermented materials with high moisture content, high viscosity, and high straw fiber content, 3-5 minutes are needed; for finely formulated fertilizers with added microbial agents and trace elements, the mixing time can be extended to 4-6 minutes to ensure uniformity and avoid uneven distribution of trace components.

Second, dynamically adjust according to the production rhythm of the fertilizer making machine. For continuous production lines, the mixing time must be matched with the preceding and following stages. Too short a time will result in undermixed material, with some areas not being evenly mixed, affecting subsequent granulation and fertilizer efficiency; too long a time not only wastes energy and reduces output but also leads to excessive grinding of materials, shortened fibers, and even clumping against the walls, thus reducing uniformity.

During operation, follow the principle of "fast first, then stable." Before starting the machine, run it idle for inspection. Begin timing after feeding is complete, and avoid stopping the machine arbitrarily or frequently adding or subtracting materials. You can judge the mixing status by taking samples: consistent material color, no obvious lumps, and no stratification indicate proper mixing.

Routine equipment maintenance is essential to ensure effective mixing time. Excessive wear, deformation, or incorrect installation angle of the twin-shaft blades or impellers can create mixing dead zones, making it difficult to achieve uniform mixing even with extended mixing time. Ensure proper lubrication of bearings and the reducer to guarantee stable speed and avoid fluctuations in actual mixing results due to unstable speed.

For batch production, it is recommended to fix the standard mixing time and strictly adhere to it for each batch. This ensures consistent organic fertilizer quality, maximizes production capacity, reduces energy consumption, and achieves efficient and stable production.
