The key considerations for horizontal fetilizer mixing machines revolve around four dimensions: mixing effect, fertilizer produciton machine durability, production adaptability, and operational safety.  The following are key aspects to pay attention to during practical operation, suitable for mixing organic fertilizer and compound fertilizer raw materials:

1. Mixing Uniformity: Consider the paddle structure (double helix/ribbon type is preferred), the gap between the paddles and the cylinder wall (≤5mm), and whether it has an anti-bridging design to prevent material stratification and dead spots, ensuring uniform fertilizer effectiveness.

2. Material and Corrosion Resistance: The parts in contact with the materials should preferably be made of 304 stainless steel/thickened manganese steel. Organic fertilizer fermentation materials are acidic, requiring anti-corrosion treatment to prevent equipment rust and contamination of raw materials.

3. Sealing Performance: The shaft end adopts a double-seal (packing + mechanical seal) design to prevent dust leakage and material spillage, and to prevent dust from entering and jamming the bearings, adapting to the dusty environment of fertilizer production.

4. Rotation Speed ​​and Mixing Time: Organic fertilizers should be mixed slowly at low speed (15-30 r/min) to prevent material breakage; for compound fertilizer granules, the rotation speed needs to be controlled to avoid granule wear, balancing mixing efficiency and material integrity.

5. Safety and Maintenance: Equipped with emergency stop buttons and lid opening power-off protection, the paddles are easy to disassemble and replace, and wear parts such as bearings and reducers are selected from common models, facilitating daily maintenance and parts replacement, reducing downtime costs.

6. Production Capacity and Adaptability: Select the cylinder volume according to the production line capacity, and confirm whether the equipment supports continuous/batch production, and whether it can be connected to feeding and conveying equipment to achieve assembly line linkage.

7. Anti-sticking Design: The inner wall can be coated with an anti-sticking coating, and the ribbon paddles have a self-cleaning structure. This is especially important for wet organic fertilizers and sticky raw materials, preventing wall adhesion and clumping, ensuring mixing efficiency and equipment lifespan.
