I. GFM-1L Dry Bead Mill

1. Grinding, Classification, Dust Removal and Collection in One Integrated System
The GFM-1L Dry Bead Mill combines grinding, classification, dust removal, and powder collection within a single closed-loop system, eliminating the material transfer and exposure steps required by separate standalone equipment.
Raw material is quantitatively fed into the grinding chamber, reduced through high-frequency shear and impact crushing, classified by centrifugal force into coarse and fine fractions, and the qualified fine powder is recovered directly through a cyclone separator and bag dust collector — all within one continuous process.

2. A Reliable Dry Grinding Option for Sulfide Solid-State Electrolyte Processing
Sulfide solid-state electrolyte materials are highly sensitive to moisture and oxygen, making dry, liquid-free grinding methods a preferred choice over conventional wet processing for certain stages of the production line.
The GFM-1L Dry Bead Mill's fully enclosed grinding and separation chamber, combined with a contamination-free design, helps maintain a low-moisture processing environment while achieving stable, high-precision particle size control — supporting the dry grinding and dispersion requirements found in sulfide solid-state electrolyte production lines.

3. Laboratory-Scale Precision for R&D and Small-Batch Validation
With a batch capacity of 1.5-5 kg powder per run and energy consumption of approximately 3 kWh, the GFM-1L is sized for laboratory research and small-batch process development, allowing engineers to validate dry grinding parameters before scaling up to pilot or mass-production lines.
Asymmetric membrane design and plastic flow separation device; spindle speed: Φ590/1min; impeller speed: 4~6m/s; bidirectional vortex formed by counter-rotation.
Oxidation filter (pore size gradient design) with maximum surface density processing and filling performance (>99.2%).
The labyrinth seal adopts precision axial radial gap control (0.05-0.1mm) and multi-stage meandering runner design, forming an efficient pneumatic barrier under 0.3MPa gas pressure.

① Quantitative Input of Raw Material:The raw material is measured by a high-precision quantitative feeder and transported to the GFM dry bead mill.
② Crushing Coarse Powder Particles:Coarse powder is sent to the crushing zone, where particles are broken by high-frequency collisions between the impeller and grinding beads in the grinding chamber.
③ Full Shear Crushing:Under the action of the grinding rotor, the beads and material fully collide and undergo shear crushing, then are sent to the classification zone.
④ Grinding and Classification:After crushing, the material is classified into coarse and fine powder by centrifugal force; coarse powder returns to the grinding zone.
⑤ Fine Powder Separation and Recovery:Fine powder is discharged from the GFM dry bead mill and recovered via a cyclone separator and bag filter.
