Typical fields of application: Soft materials like plants, wood, roots, leaves, coniferous needles, spices, textiles, leather, chemicals, foodstuffs, grains, cellulose, fillers, chalk, kaolin, coal, soils (without stones). Medium-hard samples like drugs, tablets, fertilisers, pellets, fodder; Temperature-sensitive samples can be ground, because of the rapid, effective grinding, the heat absorption of the material is reduced. Materials which are difficult to grind such as styrene, polyester, plastics, foils, PVC, PP and PE can be embrittled for example by liquid nitrogen, prior to grinding and good results can be expected for analytical purposes.

Method of operation: A high-speed rotor with shaped ribs crushes the sample by force. In addition, the sharp edged teeth and the sieve insert reduce the sample by shearing. The sample is placed under stress in the last milling stage by friction between the rotor and the sieve insert.

Features of performance: Interchangeable system consisting of rotor, collection vessel, sieve insert and labyrinth seal, system can be completely removed and inserted again without tools
Controlled rotor torque (6.000-20.000 rpm)
Optimum cooling in grinding chamber due to very high air throughput
Highly resilient, wear-resistant rotor made of specially selected grade stainless steel
Wear-resistant labyrinth seal between grinding chamber and drive motor
High speed stability even under full load
conversion kit for iron free grinding

Equipment: The Variable Speed Rotor Mill is delivered with collecting vessel, but without rotor and sieve ring. Rotors and sieve rings are available in different types and materials and must be ordered as accessories.
