Ball mill (ball-miller)

Equipment model
Pulverisette 6
Made in
Use for
  • Ball milling apparatus can realize planetary ball milling process for rapid batch wise ultra fine grinding down to colloidal fineness of hard to soft materials dry or in suspensions. Milling process possible in inert as well as reactive gas atmosphere.
  • Special interest is paid to synthesis of hydrogen storage materials by reactive ball milling under high hydrogen pressure of at least 150 bars.
