  Vibration ball mill

  A laboratory vibration ball mill for fast, ultra-fine grinding of hard, brittle and fibrous samples. High-frequency vibration of the chamber breaks the material down in minutes — dry or wet, in small batches for sample preparation.

  • High-frequency vibration — grinding in minutes
  • Ultra-fine result for sample preparation
  • Hard, brittle and fibrous materials
  • Dry and wet grinding
