CONDUX CUM Universal Mill

General Information

The Universal Mill, CUM, is a high speed fine impact mill for the dry grinding of various products up to a Mohs hardness of 3 - 3,5. The diversity of grinding tools allow the mill to be used "universally" depending on the application and area of operation. This of course also applies later on, when circumstances such as product characteristics or requirements have changed, the grinding tools can be changed as well.

Depending on the application and product, the mill is equipped with differing rotor and stator variations and can be operated as any of the following mill types: Pin Mill, Blast Mill, Beater Mill or Attrition Disc Mill.

One design variant with 2 housing doors can be used either as a single rotor or a counter-rotating pin mill.
