Available in single- or dual-grinding station models, they produce extremely high centrifugal forces, generating very high pulverization energies resulting in short grinding times.

  • Energy and speed control enables reproducible results
  • Graphic display and one-button operation for setting speed, time, energy input, grinding direction reversal
  • Powerful, maintenance-free drive maintains constant controlled speed for continuous use
  • Memory stores up to 10 combinations of grinding parameters for repetitive tasks
  • Maximum timed run: 99 hours, 59 minutes, 59 seconds
  • Built-in automatic fan ventilates chamber for safe wet grinding with solvents
