ultra Centrifugal Mill ZM 200
The powerful and versatile ZM 200 offers the ultimate in performance and operating comfort. This widely used mill pulverizes a great variety of substances extremely fast, thus allowing for a high sample throughput without degradation of sample properties. The grinding sets can be cleaned easily without any tools which helps to avoid cross contamination from frequently changing samples.

Thanks to the vast range of accessories with differ- ent rotors, ring sieves and collecting systems, the ZM 200 can be easily adapted to suit a wide range of applications.

  • Robust high torque motor with speed range from 6,000 to 18,000 rpm
  • rapid and gentle size reduction by 2-step rotor/screen system
  • Easy to operate and clean
  • Automatic feeding system for sample volumes of up to 4.5 liters

Main areas of application

Bones, cereals, chemicals, coal, drugs, fertilizers, food & feed, minerals, plastics, pharmaceutical products, plant materials, powder coatings, secondary fuels, spices

Performance data ZM 200
Application Fine grinding
Feed material soft, medium -hard, brittle, fibrous
Feed size* <10 mm
Final fineness* <40 mm
* depending on feed material and instrument configuration / settings
Cyclone Mill Twister
The cyclone mill TWISTER is used for the sample preparation prior to NIR analysis. It is suitable for the quick and gentle grinding of fibrous and soft products down to analytical fineness. Typical applications include feeds, forage and grain. The high speed and the optimized form of the rotor and the grinding chamber generate an air jet which carries the sample through the cyclone into the sample bottle and also has a cooling effect on the material.
  • 3 controlled speeds
  • Cyclone separator with 250 ml collecting bottle for quick sample extraction
  • no cross contamination thanks to easy cleaning
Performance data TWISTER
Application Sample preparation for NIR analysis
Feed material fibrous, soft
Feed size* < 10 mm
Final fineness* < 500 um
* depending on feed material and instrument configuration / settings

Main areas of application

Feed and forage, grain, Pharmaceuticals, tobacco

Rotor Beater Mills SR 200 and Sr 300
Due to their robust design and their ability to process large amounts of sample, the Rotor Beater Mills SR 200 and SR 300 are ideal for small-scale production and are also suitable for installation into automated preparation systems. The SR 300 is the leader among the Rotor Beater Mills. Its high speed allows a high sample throughput. Grinding chamber, feed hopper and material inlet and outlet are completely made from high-quality stainless steel.
  • High throughput
  • Final fineness down to 50 μm
  • Easy handling and cleaning
  • Exchangeable grinding and sieve inserts
  • distance rotor for thermally sensitive samples
  • Quick-action door lock and motor brake

Application size reduction, deagglomeration
Feed material soft, medium-hard
Feed size* < 15 mm
Final fineness* < 80 um / <50 um
* depending on feed material and instrument configuration / settings

Main areas of application

Chemicals, coal, construction materials, drugs, spices, feed pellets, fertilizers, grains, seeds, pharmaceuticals, soils

Cross Beater mill SK 100
Like the Rotor Beater Mills, the Cross Beater Mill SK 100 is suitable for coarse and fine size reduction, either in batches or continuously. This robust mill is used in the laboratory as well as under rough conditions in production facilities. Due to its powerful drive, it is often possible to achieve a fineness < 100 μm in a single working step. Moreover, the SK 100 offers the highest possible degree of operating safety.
  • High throughput
  • Final fineness down to 100 μm
  • Easy handling and cleaning
  • Wide range of accessories
Performance data data SK 100
