Higher grinding fineness Dependent on the type, the max. relative speed of both discs is up to approx. 240 ms. Single-rotor pin, beater, cross-flow and turbo mills, etc. are unable to reach this high speed. The Contraplex therefore produces higher fineness values - especially with all brittle and crystalline materials.
