Application:The Cyclone Mill TWISTER is specially designed for the processing of foods and feeds for subsequent NIR analysis. The optimized form of rotor and grinding chamber generates an air jet which carries the ground sample through the integrated cyclone into the sample bottle. The air jet prevents the material from heating up, thus preserving the moisture content.Features:Ideal for grinding feeds, grains, forage and other similar products3 controlled speedsCyclone separator with 250 ml collecting bottle for quick extraction of sampleNo cross contamination thanks to easy cleaningConvenient operating panelProfessional industrial design with long lifetimeSpecifications:Feed size:
The cross beater mill SK 300 is used for batch-wise or continuous preliminary and fine size reduction. This robust mill is suited for laboratories as well as for the rough conditions of a production environment. Thanks to the powerful drive and rotor speed up to 4000 rpm it is often possible to achieve a final fineness <100 microns in one process.Features:High throughput for batch-wise size reduction of large sample volumesDefined final fineness due to bottom sieves with aperture sizes from 0.12 to 10 mmRapid cleaning thanks to easily removable cassette, hopper and push fit rotorRing filter and collecting vessel with convenient, dust-tight bayonet catchQuick-action door lock safety lock and electric brakeFunction principle:Size reduction in the SK 300 takes place by impact and shearing effects. The air drawn in through the hopper by the cross beater accelerates the discharge of the ground material. The airborne fine fraction is separated off by a downstream filter system.Scope of supply: Cross Beater Mill with grinding insert, cross beater, baffle plates, filter hose, 5 l collecting vesselBottom sieves and base frame, please order separately.Feeders and bottom sieves in further sizes are available on request.

The Emax is an entirely new type of ball mill for high energy milling for medium-hard, hard, brittle and fibrous materials. The combination of high friction and impact results in extremely fine particles within the shortest amount of time. Thanks to the cooling system with water, the high energy input is effectively used for the grinding process without overheating the sample. The Emax is capable of continuous grinding operation without interruptions for cooling down. The high energy input in combination with the unique cooling system provides perfect conditions for effective mechanical alloying or grinding down to the nanometer range.Speed of 2000 rpm allows for ultra-fast and fine pulverization of the sampleControlled water cooling allows for continuous operation without cool down breaksTemperature-controlled grindingNarrow particle size distribution thanks to special jar design which improves mixing of the sample10 combinations of grinding parameters storableOperation with 2 grinding jars with integrated safety closureRange of jar materials allow for contamination free grindingAccessories on request.

The CryoMill is designed for the cryogenic size reduction of materials which cannot be ground at room temperature or whose composition would be changed by it. The grinding jar is cooled before and during the grinding process with liquid nitrogen through an integrated cooling system. Thus the sample is embrittled and its volatile components are preserved. The size reduction principle is the same as that of the well-proven Mixer Mill MM 400. The CryoMill can also be operated without the cooling system which makes it suitable for a wide range of applications.Powerful cryogenic grinding by impact and friction, up to 30 HzClosed LN2-system (autofill) for enhanced safety, avoids any contact of the user with LN2Screw-top grinding jars for convenient, leak-proof operationClearly structured user interface, memory for 9 SOPsWide range of accessories including LN2feeding systems, various jar and ball sizes, adapter racks, materialsPlease order Autofill, grinding jars and grinding balls separately.

Retsch planetary ball mills such as the PM 100 can achieve final fineness down to 1 micron (µm) depending on material hardness, grinding jar material, and run time. For nanoscale grinding requirements, Retsch's high-energy ball mills can reach submicron particle sizes. Contact us with your material type and target particle size for a specific recommendation.
The PM 100 operates with one grinding jar and suits small sample volumes. The PM 200 runs two jars simultaneously for higher throughput. The PM 400 handles up to four jars and is designed for production-scale sample preparation. The right choice depends on your batch size, material type, and required fineness. We can advise based on your specific workflow.
All Retsch equipment comes with the manufacturer's standard warranty. We assist with warranty claims, spare parts sourcing (grinding jars, lids, balls), and service escalation.
