Core Advantages: Efficient, Uniform, Low Residue
The design philosophy of the horizontal mixer aims to achieve the optimal balance between mixing effectiveness and equipment reliability, offering distinct core advantages:
Exceptional Three-Dimensional Mixing Uniformity: The machine features a horizontally positioned mixing drum, typically equipped with a dual-ribbon or paddle-type agitator rotor. During operation, the outer ribbon conveys material from both ends of the drum toward the center, while the inner ribbon simultaneously transports material from the center toward the ends. This creates intense bidirectional convection and shear diffusion. This compound motion ensures materials of different densities and particle sizes achieve a high degree of microscopic homogeneity in a short time.
Very Low Residue and Complete Discharge: The precise fit between the unique U-shaped drum and the mixing blades, combined with a full-length, large bottom discharge gate, allows for rapid, dead-zone-free discharge with extremely low material residue. This characteristic is vital for industries requiring frequent formula changes and strict prevention of cross-contamination, such as food, pharmaceuticals, and premium animal feed.
Smooth Operation and Excellent Sealing: The horizontal structure ensures an even load on the drive system, resulting in low-noise, low-vibration operation. The shaft ends employ multiple sealing designs, effectively preventing the escape of fine dust and contamination by lubricants. This makes it particularly suitable for handling materials with special hygiene or safety requirements.
Gentle Mixing Process: Compared to some high-shear vertical disc mixers, the mixing action of the horizontal mixer is more uniform and gentle, causing minimal damage to the original crystalline structure of materials or the integrity of already formed granules. It is an ideal choice for handling finished compound fertilizers, bulk blend (BB) fertilizer blender raw materials, or fragile materials.
Wide Capacity Range and Material Adaptability: Ranging from small laboratory-scale models to large industrial units capable of handling several tons per batch, horizontal mixers meet diverse production needs. They perform effectively with dry powders, granules, short fibers, and pastes with a certain degree of moisture.
Working Principle: Precision Convection on a Horizontal Axis
Taking the most common dual-ribbon horizontal mixer as an example, its operation is a precise exercise in mechanical convection:
Loading: Material is loaded into the U-shaped mixing drum via the top inlet, with a fill ratio typically between 40% and 70%.
Mixing: The drive unit rotates the dual ribbon shafts synchronously. The outer ribbons convey material along the drum wall from the ends toward the center, while the inner ribbons push material from the center toward the ends, creating a powerful axial main circulatory flow.
Homogenization: Concurrent with macroscopic convection, inter-particle collisions and the shearing action generated at the ribbon edges further promote microscopic mixing in the radial and circumferential directions, thoroughly breaking up agglomerates to achieve homogeneous distribution of components
Discharge: Upon completion of mixing, the bottom discharge gate opens rapidly, emptying the drum completely within seconds.
