Key Features – Why PPCELL Double Planetary Mixer?
- 3D‑printed kneading blades – Investment casting + CNC multi‑axis finishing. Optimized aerodynamic cross‑section reduces drag and energy consumption, achieving 4‑5x higher mixing efficiency than conventional pentagonal paddle blades.
- Planetary + high‑speed dispersion – The planetary frame rotates while blades self‑rotate, forcing material to flow vertically and radially. An independent disperser (2980 rpm) provides intense shear for deagglomeration and emulsification.
- No dead corners & self‑cleaning – The vessel wall is precision‑polished, and the scraping blade continuously removes adhered material, ensuring uniform mixing without residue.
- Vacuum degassing (optional) – Mix under vacuum (≤ -0.095 MPa) to remove bubbles, prevent oxidation, and enable vacuum feeding, reducing material loss and improving hygiene.
- Precise temperature control – Jacketed vessel allows heating, cooling, or constant temperature control to optimize rheology for different formulations.
- High torque output – Designed for extremely viscous products such as polyurethane, silicone, silver‑aluminum paste, and structural adhesives.
Applications
This electrode slurry mixer and double planetary mixer is widely used in:
- Battery industry – Lithium-ion battery electrode slurry (cathode & anode), solid‑state electrolyte paste, conductive coatings.
- Adhesives & sealants – Polyurethane, epoxy, silicone, hot‑melt adhesives.
- Electronic pastes – Silver paste, aluminum paste, conductive inks.
- Cosmetics & pharmaceuticals – Creams, gels, ointments.
- Composites & ceramics – Particle‑reinforced slurries, ceramic binders.
FAQ – Frequently Asked Questions
Q1: What is the advantage of a double planetary mixer over a conventional mixer?
Double planetary mixers generate extremely high torque and provide thorough kneading action. The dual blades rotate on their own axes while orbiting the vessel, eliminating dead zones and ensuring uniform mixing even for high‑viscosity pastes (up to 1,000,000 cP). This is critical for battery slurries and thick adhesives.
Q2: Can this mixer be used for water‑based and solvent‑based slurries?
Yes. The vessel and blades are made of SUS304 stainless steel, resistant to both water‑based and organic solvents. For flammable solvents, we offer explosion‑proof electrical configurations.
Q3: How does the 3D‑printed blade improve efficiency?
Our blades are investment‑cast via 3D printing and finished with multi‑axis CNC, resulting in an optimized aerodynamic profile. This reduces drag and energy consumption while creating kneading, extrusion, and granulation actions – delivering 4‑5x higher mixing efficiency than conventional blades.
Q4: Is vacuum mixing necessary?
Vacuum mixing removes entrapped air bubbles, prevents solvent evaporation, and allows bubble‑free casting or coating. It is highly recommended for battery electrode slurries, electronic pastes, and degassing‑sensitive materials.
Q5: What is the typical batch size for this 2L mixer?
The working capacity is 2L, but for high‑viscosity pastes, the effective batch size is typically 1.0‑1.8L depending on material density and rheology. It is ideal for R&D and small‑scale formulation development.
Q6: Can I customize the mixer for specific applications?
Yes. PPCELL offers custom blades (frame type, paddle type, twisted frame), higher dispersion speed/power, explosion‑proof electricals, and PLC automation. Contact us with your requirements.
Q7:What are the typical application areas of this mixer?
Answer: It is mainly used in fields such as lithium battery positive and negative electrode slurries, adhesives, polyurethane, silicone, silver-aluminum paste, electronic paste, and medical ointments.
