CS-Z Fine Cutting Mill

The finest cut!

The fine cutting mill CS-Z for the size reduction of non-friable and soft products.

By maximizing the cutting strokes (rotational speed of the rotor x number of rotor knives x number of stator knives) and the use of special screen inserts, highest finenesses can be achieved with this multi-knife cutting mill. The open rotor design increases the air flow, the results of which are a high throughput capacity, good powder quality and the highest bulk density.

Due to the central position of the feed inlet, product can be fed without danger of overloading!

Continuous feeding of rolled product is possible when specially designed feeding systems are mounted on top of the machine inlet.



  • Finenesses from 0.1 to 3 mm
  • Multi-knife cutting mill for the fine cutting of non-friable and soft products
  • Fineness adjustment through a wide selection of screen perforations
  • Variable number of knives
  • Bearing of the rotor shaft in heavy roller bearing with continuous heat exhaust through water-cooled flange bearing shields
  • Particle contamination of the bearing housing is prevented by air rinsing of the bearing seal to the cutting chamber of the machine
  • High rotational speed of the cutting rotors
  • Effective cooling of product directly on the cutting surfaces
  • Energy saving due to real shear cut
  • High cutting capacity through maximized cutting strokes
  • Extreme stability due to robust design
  • Fast knife changes made possible by easy, exact rotor knife adjustment
  • Fast, easy screen changes without tools
  • Water cooled housing designs available
  • Pressure shock resistant designs also available

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

SecoMy® Fine Cutting Mill

The fast operating fine cutting mills SecoMy® are the choice for the pulverization of fibrous, ductile, soft, viscoplastic or temperature-sensitive products. This type of cutting mill distinguishes itself through the optimization of number and position of the knives and the high cutting stroke rate.

Machine sizes available with drive capacities from 37 to 200 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.
