GFM-1L Dry Bead Mill

The GFM-IL Dry Bead Mill is a highly efficient and precise hydration processing
equipment , designed for laboratory and dry grinding applications.

Its core advantages lie in enhancing medium precision and achieving fine
particle refinement, making it suitable for processing high-temperature
materials, ceramic fibers, metal oxides, and other wear-resistant applications.

The equipment features full-chain integration, a dynamic centrifugal force
system, and loop temperature management, ensuring excellent grinding efficiency
while delivering contamination-free and highly stable grinding results.

The GFM-1L Dry Bead Mill exemplifies the capabilities of advanced Bead
Mills and Bead Grinding Machines. Its combination of high precision,
efficient dry grinding, and robust material handling makes it an ideal choice
for laboratories and industrial applications requiring fine particle
refinement. By integrating dynamic centrifugal force, loop temperature control,
and full-chain processing, this Bead Grinding Machine ensures consistent,
contamination-free results, highlighting the superior performance and
reliability of modern Bead Mills.

Equipment advantage
01 Asymmetric membrane design and plastic flow separation device; spindle speed:
Φ590/1min; impeller speed: 4~6m/s; bidirectional vortex formed by counter-
rotation.
02 Oxidation filter (pore size gradient design) with maximum surface density
processing and filling performance (>99.2%).
03 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.

Dry Grinding Process
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.
