Core Features & Advantages
- 3D‑printed kneading blades – Investment casting + CNC multi‑axis finishing. Optimized cross‑section reduces drag and energy consumption, delivering 4-5x higher mixing efficiency than conventional pentagonal paddle blades.
- Planetary motion + high‑speed dispersion – Dual blades rotate on their own axes while orbiting the vessel, eliminating dead zones. Independent disperser (up to 2980 rpm) provides intense shear for rapid deagglomeration.
- Vacuum degassing (≤ -0.095 MPa) – Removes air bubbles that cause pinhole defects in coating, prevents solvent evaporation, and ensures homogeneous bubble‑free slurry.
- No dead corners – Polished vessel wall with continuous scraping blade eliminates residue, ensuring batch consistency and easy cleaning.
- Precise temperature control – Jacketed vessel with electric, steam, or oil heating options, paired with intelligent PID controller for accurate temperature regulation.
- High torque output – Planetary gear transmission provides large torque for high‑viscosity, high‑solid content pastes (e.g., silicone, polyurethane, structural adhesives).
- Hydraulic discharge system (optional) – Follow‑plate extruder simplifies high‑viscosity paste discharge, minimizing waste and cleaning effort.
- Flexible blade options – Choose from kneading, frame, paddle, or twisted blades to match your specific material and process requirements.
Applications – Slurry Mixing Machine for Battery & Beyond
Our planetary vacuum mixer is widely used as a slurry mixing machine for:

- Solid‑state batteries – Electrolyte pastes and composite slurries
- Adhesives & sealants – Polyurethane, epoxy, silicone, hot‑melt adhesives
- Electronic pastes – Conductive silver paste, aluminum paste, die attach adhesives
- Composites & ceramics – Fiber‑reinforced slurries, ceramic binders
- Cosmetics & pharmaceuticals – Creams, gels, ointments, pastes
FAQ – Frequently Asked Questions
Q1: What is the advantage of a planetary mixer over a traditional mixer for battery slurry?
A: Planetary mixers generate high torque and provide a combination of planetary revolution and blade self‑rotation, eliminating dead zones. This ensures uniform mixing of high‑viscosity, high‑solid content slurries – critical for consistent electrode coating and cell performance.
Q2: Can this mixer handle both water‑based anode and NMP‑based cathode slurries?
A: Yes. The stainless steel vessel and blades are compatible with both water‑based and organic solvent systems. For flammable solvents, we offer explosion‑proof electrical configurations.
Q3: How does the vacuum degassing function improve slurry quality?
A: Vacuum mixing removes entrapped air bubbles that would otherwise cause pinholes, coating defects, and poor adhesion. It also prevents solvent evaporation, enabling vacuum feeding that reduces material loss and improves batch consistency.
Q4: Is temperature control available?
A: Yes. The jacketed vessel can be connected to an external circulator (electric heater, steam, hot oil, or water system) for precise heating or cooling. An intelligent PID controller maintains set temperature with high accuracy – essential for optimizing the rheology of temperature‑sensitive formulations.
Q5: Can I scale up from a laboratory model to a production unit?
A: Absolutely. PPCELL offers planetary mixers from 2L laboratory units to 100L, 300L, 500L, 1000L, and 2000L production models, with similar geometry and mixing action for reliable scale‑up. Process parameters developed on smaller units can be directly transferred to larger models.
Q6: What certifications do PPCELL mixers have?
A: Our mixers are CE certified and can be configured with ATEX / explosion‑proof components for hazardous environments. All electrical components meet international safety standards.
