Working principle and wide application of horizontal screw belt mixer
Date: 2025-10-11Read: 6
The horizontal spiral belt mixer is an efficient powder mixing equipment, and its core working principle is based on the convective shear action of double-layer spiral blades. The inner spiral transports the material from the axis to both sides, while the outer spiral gathers the material from the cylinder wall to the center, forming axial bidirectional flow and radial turbulence. Combined with the shear force generated by the gap between the spiral edge and the cylinder wall, it achieves full penetration and diffusion of particles. This structure allows the material filling rate to reach 60% -70%, and the mixing cycle is shortened by more than 30% compared to traditional equipment.
This device is widely used in multiple fields:
1. Chemical and new energy: dispersion of lithium battery cathode materials and conductive agents, mixing of dyes, etc. 316L stainless steel material can resist acid corrosion;
2. Food and medicine: Mixing milk powder with probiotics requires GMP standard mirror polishing (Ra ≤ 0.4 μ m), and some models are equipped with nitrogen protection to prevent oxidation;
3. Building materials and feed: homogenization of dry mortar and vitamin premix, with a mixing coefficient of variation reduced to within 3%;
4. Special material handling: Viscous materials (such as adhesives) are treated with a scraper structure to solve residual problems, while high-precision materials are discharged using pneumatic butterfly valves for dust-free discharge.
