FRM Series High-Speed Mixer
The FRM Series is a guide-plate-free high speed mixing system for dry powder blending in the 13–3150 L total chamber range.
A three-tier blade assembly — no guide plates, no direct particle collision — achieves micro-level homogenization through inter-particle velocity differential and friction, preserving particle morphology across all operating speeds.
Eight models cover laboratory through full production scale. Standard blade linear speed up to 40 m/s, with custom configurations available to 100 m/s. Integrated cooling jacket for temperature-sensitive materials such as high-nickel cathode precursors.

OPERATING PRINCIPLE
A three-tier blade assembly rotates inside the vertical sealed chamber:
- Upper blades — V-shaped, mixing function
- Middle blades — straight, flow function
- Lower blades — large-radius angled, elevating function
Peripheral powder rises along the chamber wall.
Central powder descends simultaneously.
This opposing vertical circulation generates velocity and directional differentials between particles — micro-level homogenization driven entirely by high-speed inter-particle friction, no external impact force required.
Guide plates are eliminated from the chamber design.
Without direct high-velocity particle-wall impact, particle morphology is preserved across all operating speeds — including high-nickel NCA and NMC 811 formulations where sphericity is critical.
Standard blade linear speed up to 40 m/s; custom configurations available to 100 m/s.
XPC multi-V-belt drive with dual-end pulley support delivers low vibration at high RPM.
Product discharges through a pneumatic curved-plug valve with O-ring cylinder seal —
zero leakage across repeated open-close cycles, no residual powder at the discharge port.
KEY FEATURES
- Guide-plate-free chamber
No direct particle collision, no dead zones — particle morphology preserved at any operating speed - Three-tier blade assembly (V-type / straight / large-radius angled)
Standard blade linear speed: up to 40 m/s
Custom configuration: up to 100 m/s - Dual-seal spindle system
