The structural design principle of organic fertilizer mixers is closely related to their working process and performance. Each structural component carries a specific function, jointly ensuring the efficient operation of the equipment.

The shell of the mixer is the basic framework of the entire equipment, usually welded from high-strength steel. The design of the shell should not only ensure sufficient strength and rigidity to withstand the huge forces generated during the mixing process, but also have good sealing performance. A sealed casing can prevent material leakage, avoid pollution to the production environment, and also prevent external impurities from entering the interior of the mixer, affecting the mixing quality of materials.

The mixing shaft is one of the core components of the mixer, which runs through the entire interior of the mixer. The design of the mixing shaft needs to consider torque transmission and stability. In order to withstand the huge torque during the mixing process, the mixing shaft is usually made of solid shaft and undergoes special heat treatment process to improve its strength and toughness. The two ends of the mixing shaft are supported on the housing by bearings, and the selection and installation accuracy of the bearings are crucial for the smooth rotation of the mixing shaft. Appropriate bearings can reduce friction and vibration, and extend the service life of the mixing shaft.

The mixing component installed on the mixing shaft is the key to achieving material mixing. The shape, size, and layout of the mixing components such as the spiral blades and paddles of the organic fertilizer mixer have been carefully designed. The pitch and diameter of spiral blades determine the speed and distance of axial material transportation, and different pitch designs can achieve varying degrees of material propulsion effects. The shape and angle of the blade affect the radial motion and stirring intensity of the material. By reasonably matching the number, position, and angle of spiral blades and paddles, the material can form a complex and effective flow pattern inside the mixer, achieving all-round and uniform mixing.

In order to facilitate the entry and exit of materials, the mixer is equipped with inlet and outlet ports. The position and size of the feeding port are designed according to the feeding method and material characteristics to ensure that the material can smoothly enter the interior of the mixer. The discharge port is usually located at the bottom of the mixer, and its size and shape should ensure that the mixed material can be quickly and smoothly discharged. Some mixers are also equipped with valves or regulating devices at the discharge outlet to better control the discharge speed and flow rate.

In addition, the structural design of the organic fertilizer mixer also considers the maintenance and repair needs of the equipment. For example, a maintenance door is installed on the outer shell to facilitate operators to enter the interior of the mixer for cleaning, inspection, and maintenance. At the same time, some key components, such as mixing shafts and mixing parts, are designed as detachable structures for easy replacement and maintenance. Through these scientifically reasonable structural design principles, the various components of the organic fertilizer mixer work together to achieve efficient material mixing and blending, meeting the practical needs of organic fertilizer production.
