Disc Mill DM 400

Name: DM 400
Brand: Retsch

The DM 400 is the new comfort model for fine grinding of medium-hard, hard and brittle materials down to 0.05 mm.This model is based on the well-proven DM 200 but offers improved safety features due to the automatic locking of the collecting vessel and grinding chamber, as well as particularly convenient operation thanks to the motor-driven grinding gap adjustment with digital gap display. The clearly structured display shows all grinding parameters.

Thanks to its robust design, the Disc Mill DM 400 can be used under rough conditions in laboratories and pilot plants, as well as online for the quality control of raw materials. The powerful DM 400 requires only a few minutes to achieve the desired grind size.
