What is a fertilizer horizontal mixer used for?
A fertilizer horizontal mixer is a core piece of equipment in the production process of compound fertilizers and organic fertilizers, used for homogenizing raw materials. Its design is fully adapted to the specific needs of fertilizer production, playing an irreplaceable role in improving fertilizer quality.
Structurally, it typically uses a horizontally placed cylindrical body, providing ample mixing space for the materials. Inside the cylinder, the mixing shaft is equipped with mixing blades at different angles, commonly paddle-type and ribbon-type. Paddle-type blades violently tumble the material radially, while ribbon-type blades propel the material in axial circulation. The superposition of these two motion trajectories creates complex convection and shearing within the cylinder, ensuring thorough mixing of different raw materials.
In compound fertilizer production, its role is particularly crucial. When single-element fertilizers such as nitrogen, phosphorus, and potassium are added in proportion, the mixer, through continuous operation, eliminates density differences between raw material particles, preventing stratification caused by differences in specific gravity.
In organic fertilizer production, it is responsible for harmonizing the properties of the materials. Well-rotted livestock manure, straw, and other raw materials often have uneven moisture content and contain coarse fibrous impurities. The mixer, through the kneading and crushing action of its blades, can evenly mix the materials with conditioning agents (such as wood ash and vermiculite), regulating moisture content and refining particle size. This provides a loose, homogeneous raw material for subsequent granulation processes.
In short, the fertilizer horizontal mixer, by precisely controlling the movement of materials, transforms raw materials with varying properties into a homogeneous and stable mixture. It is not only a "harmonizer" in the organic fertilizer produciton line but also a crucial link in ensuring fertilizer application effectiveness and achieving a balanced nutrient supply.
