GFM-5L Dry Bead Mill

Principles of Mechanical Grinding

The ceramic rotor spins at high speed to drive the zirconia beads into motion. Through intense collisions between the zirconia beads and the material, large particles are broken down. Subsequently, the friction between the zirconia beads and the material, as well as between the material and the chamber, further refines the material to the target particle size.

Principles of Precise Grading

The classier utilizes specific airflow and mechanical structures to screen materials based on particle size and density differences, ensuring qualified particles enter the collection stage and achieving precise particle size control.

Principle of Efficient Collection

The combination of a cyclone collector and dust collector is employed, where the cyclone collector recovers bulk material through centrifugal force, while the dust collector captures fine powder via filtration, achieving waste-free material recovery in Dry Bead Mill applications.

I. GFM-5L Dry Bead Mill

1. One System for Grinding, Classification, Dust Removal and Material Collection

The GFM-5L Dry Bead Mill integrates grinding, real-time classification, dust removal, and fine powder collection into a single production unit, reducing the number of transfer points where fine, sensitive powders would otherwise be exposed to ambient air.

Beads and material are driven through continuous mechanical grinding, oversized particles are separated by the classifier wheel and returned for further grinding, and qualified fine powder is recovered through a cyclone collector and dust collector, achieving waste-free material recovery.

2. Supporting Dry Grinding and Dispersion in Sulfide Solid-State Electrolyte Lines

Since sulfide solid-state electrolytes require strict control of moisture and oxygen exposure throughout the entire processing, dry grinding equipment plays a crucial role in the grinding and dispersion stages of sulfide solid-state electrolyte production lines, working in conjunction with premixing, drying, and sintering steps.

The GFM-5L's ceramic pin-type rotor, silicon carbide cooling cylinder, and precision-controlled classifier allow it to deliver consistent submicron-level particle size distribution under stable temperature conditions, helping reduce agglomeration and supporting uniform powder quality for downstream sintering.

3. Scalable Output for Pilot-Line and Mass-Production Needs

With a production capacity of up to 100 kg/h and an effective grinding volume of 5 L, the GFM-5L bridges the gap between laboratory-scale trials and larger production runs, making it suitable for customers moving from process validation toward pilot-line or mass-production implementation.

Equipment advantage

Dry Grinding Mill provides more uniform grinding force, ensuring stable fine grinding effect.

Enhanced by fluidized bed technology achieving higher classification efficiency

Low-cost · Submicron · Zero-waste

Wear-resistant · Temperature-stable · Controllable

Integrated Grinding and Classification

More uniform grinding force stable fine grinding effect

The Nano Grinding or Nano Milling process utilizes a horizontal layout, enabling the grinding media to fully contact the material under the dual action of gravity and the stirring shaft.

Real-time finess control, with an extremely narrow particle size distribution

The classifier wheel operates synchronously with the grinding process. Based on centrifugal force, oversized particles are separated in real time and flung back into the grinding chamber for secondary grinding, while qualified particles pass through the classification gap into the collection system.

Enhanced by fluidized bed technology achieving higher classification effciency

Innovatively employing TSD classification technology, this system leverages fluidized bed air distribution to minimize pressure drop during the classification process, preventing material accumulation and blockage within the classification chamber.
