For Dry Battery Electrode (DBE) technology, the High-Speed Dry Mixer replaces the traditional NMP-based planetary mixer. Its primary function is no longer just "blending" but "Fibrillation"—the mechanical process of stretching PTFE (Polytetrafluoroethylene) binder particles into a microscopic 3D web that binds the active material together.

Dry electrode mixing relies on high-shear collision. (1) Dry Powder Loading: Active material (NMC/LFP), conductive carbon (Super P/CNTs), and PTFE binder are loaded as dry powders (typically 5–10% binder). (2) Shear Force: High-speed impellers (running at 3,000 to 10,000 RPM) create intense mechanical shear. (3) PTFE Activation: Under this shear and the heat generated by friction, the spherical PTFE particles undergo a phase transition, "uncoiling" into ultra-fine fibrils.

Part Number

Power
  • AC220V±10%, three-phases, 50/60Hz, 3000 W 
Mixing Features
  • Mixing Rotation Speed: Max. 6000 rpm (adjustable), which corresponds the line speed of 56 m/s
  • Mixing Time: 0-30 min (adjustable)
