SecoMy® Fine Cutting Mill

The finest cut!

Cutting Mills of the type SecoMy® are high speed cutting mills with high-frequency cutting strokes for the fine-grinding of cuttable materials. Application areas include materials that must be finely ground by means of cutting action, such as fibrous, ductile, soft, viscoplastic or temperature-sensitive materials for which good flowability, high density and gentle grinding are required.

Mills and classifiers for processing cellulose


The demands placed by the manufacturing industry on the technical design of mechanical plants and processes are getting tougher all the time. Gas-tight or surge pressure-resistant designs are already a must for most plant and machinery to ensure compliance with the latest regulations. New product qualities and/or methods of production also enlarge the portfolio of requirements, for example in the cellulose processing sector.

SecoMy® S Fine Cutting Mill

The fast operating fine cutting mills SecoMy® S are the choice for the pulverization of fibrous, ductile, soft, viscoplastic or temperature-sensitive products. In contrast to classic cutting mills, final finenesses of up to 45 μm can be reached in a one-step process with the SecoMy® S

CS-Z Fine Cutting Mill

These fast operating fine cutting mills are the choice for the pulverization of fibrous, soft or elastic products. This type of cutting mill distinguishes itself through the optimization of number and position of the knives and the high cutting stroke rate.

Applicable for finenesses from 0.1 to 3 mm (d97).

Machine sizes available with drive capacities from 15 to 90 kW.

Impact Mill Condux®

The mechanical fine impact mill or centrifugal mill is usually operated in the form of a pin disc mill, blast mill, wing beater mill or grooved disc mill. Many products and finenesses for a wide variety of applications are processed with the universal mill, with a wide range of rotor and stator combinations that can be easily changed. Applicable for finenesses from 30 to 800 µm (d97).

Machine sizes with drive capacities from 1.1 - 250 kW and air volume of approx. 140 - 31,000 Nm³/h.

CSM Classifier Mill

The dynamic air classifier integrated into the grinding chamber housing of this fine impact mill manufactures fine particle sizes with a defined maximum particle size limitation. Internal classification of the coarse material results in a more stable and energy efficient process than a mill with an external classification circuit. Applicable for finenesses from 10 to 150 µm (d97).

Machine sizes with drive capacities from 1.5 - 250 kW and air volume of approx. 50 - 26,000 Nm³/h.
