Planetary Ball Mills classic line (different models), FRITSCH
Planetary Ball Mills

Ideal for fast, loss-free fine grinding of hard, medium-hard, brittle and fibrous materials – dry or in suspension. Sample can be processed from a few milligrams to several kilograms at a wide range of fineness levels down to less than 1 µm. They are especially easy to operate and fast and easy to clean. They are suitable for continuous, heavy duty usage and guarantee safe clamping of the grinding bowls. Matching grinding parts of 8 different materials are available to provide maximum protection against undesired contamination. In addition to size-reduction, Planetary Ball Mills can also be used for mixing and homogenising of emulsions and pastes or for mechanical alloying and activation. Example areas: geology and mineralogy, sample preparation for analysis, ceramics, chemistry, biology, pharmaceuticals, metallurgy and much more.

Features:

  • Extremely high rotational speeds of the main disk for particularly high final finenesses
  • Very fast, uniform and reproducible size reduction
  • Loss-free grinding - also in suspensions – due to a seal ring in the grinding bowl
  • Reproducible grinding results due to controlled drive and programmable electronic system
  • Programmable interval-, break-times and reversing unit
  • RS232 interface for data transfer of process parameters (validation)
  • Microprocessor control electronic system and precise digital display of all functions (also of rotational speed)
