Title: How Do Dispersers Achieve Efficient Mixing? Technical Breakdown & 10 Key Applications
Keywords: disperser working principle, high-speed disperser applications, paint dispersion process
Technical Mechanism
Dispersers utilize motor-driven shafts rotating serrated discs (500-3000rpm) to create material vortices. Core forces include:
- Shear Force: Disc edges break particle agglomerates (nanoscale grinding)
- Impact Force: Material-wall collisions for secondary dispersion
- Circulation: Vortex ensures full-batch homogeneity (handles up to 50,000cps viscosity)
Industry Applications
| Industry | Typical Materials | Dispersion Precision |
|---|---|---|
| New Energy | Li-ion battery slurry (graphene, LiCoO₂) | ≤2μm |
| Pharmaceuticals | Vaccine adjuvants (aluminum gel) | Sterile nano-dispersion |
| Food | Chocolate slurry | Fat particle homogenization |
| Ceramics | Electronic ceramic slurry | D90<1μm |
Case Study: A solar company using vacuum planetary dispersers reduced silver paste resistivity by 18%, achieving 23.6% cell efficiency.
Selection Guide
High-viscosity: Dual-shaft + wall-scraper design (e.g., silicone sealant production)
Low-viscosity: Single-shaft dispersers (30% cost savings)
