VIBRATING MILLS Milling and Mixing

What is a Vibrating Mill?

A vibrating mill is equipment that grinds materials in a short time by generating high‑speed circular vibration of a milling chamber containing media and raw materials on springs, causing intense collisions between the media and materials.

FEATURES

  • Fine Milling ‑ Even Diamonds!

    By subjecting the milling chamber to high-speed circular vibration, strong impact forces are generated between the milling media and the material.

    This enables ultrafine milling of extremely hard materials, such as diamond.

  • Can select the milling method
    best suited to the raw material!

    • Both dry and wet milling are possible
    • A wide range of milling from medium to fine is possible
    • Can select the liner materiall
    • Can mill while cooling the milling chamber and suppressing milling heat.
    You can select the lining and media materials inside the milling chamber, such as iron, stainless steel, alumina, zirconia, rubber, nylon etc.*
    *Available materials depend on the model

  • Usable for special applications!

    • Mixing, crushing, and increasing bulk density can be performed simultaneously.
    • Inert gas milling possible (sealed milling possible)

  • Improves work efficiency!

    • Faster milling than a ball mill.
      *Milling chamber is driven in high‑speed circular vibration (1,000–1,200 cycles per minute).
    • All parts can be disassembled, making part replacement and maintenance easy.
    • Easy to automate.
    • Prevents powder scattering during material feeding and discharge, eliminating the need for dust collection equipment and maintaining a safe working environment

OTHER MILLS Other Mill Product Lines

Nylon Ball Mill (MR Type)
  • Milling
  • Mixing
Benefits
Capable of crushing, mixing, and dispersing without inorganic contamination.
Structure
Nylon-made pot and media (other materials are also available).
Water-cooled jacket option is also available.
Model
MR-30~700 Type

Nylon

Nylon Pots and Nylon Balls Available for Individual Sale

Especially used in laboratory and research applications for crushing, mixing, and dispersion.

As nylon is an organic material, even if it becomes mixed with inorganic raw materials, it will decompose and be eliminated during any subsequent firing process, therefore not creating impurities.

OTHER MILLS Ancillary Equipment

Soundproof Enclosure

Custom-made enclosures can be manufactured as required.

While vibrating mills generate noise levels of 90-110 dB during operation, installing a soundproof enclosure can reduce this by 10-15 dB.

The capacity of all these machines may vary depending on local frequencies.
