RETSCH’s new High Energy Ball Mill Emax The Emax is an entirely new type of ball mill for high energy milling. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time. The high energy input is a result of an unrivaled speed of 2000 min-1 and the innovative jar design. Thanks to the revolutionary water cooling system, the high energy input is effectively used for the grinding process without overheating the sample. Due to the special grinding jar geometry, the sample is thoroughly mixed which results in a narrow particle size distribution. Unlike other high energy ball mills, the Emax is capable of continuous grinding operation without interruptions for cooling down. This dramatically reduces the grinding time. 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. A wealth of safety features such as the integrated safety

RETSCH's PM 100 CM grinds samples in centrifugal mode The new Planetary Ball Mill PM 100 CM offers all the performance and convenience of the classic PM 100. It pulverizes and mixes soft, medium-hard to extremely hard, brittle and fibrous materials and is used wherever the highest degree of fineness down to the submicron range is required. It is suitable for dry and wet grinding. In contrast to the PM 100 the speed ratio of sun wheel to grinding jar is 1:-1, i.e. the mill operates in centrifugal mode. This results in a different ball movement so that the sample is not so much crushed by impact effects but more gently ground by pressure and friction which allows for a lower temperature rise in the grinding jar and less abrasion. The PM 100 CM offers an excellent alternative for all applications where size reduction must not necessarily be carried out with maximum energy input. Benefits: - powerful and quick grinding down to nano range - reproducible results due to energy and speed control - suitable for long-term

RETSCH has further perfected the compact bench top model of the jaw crusher series. The new BB 50 offers many features which ensure efficient and convenient usage. The speed can be set between 550 and 950 min-1 to allow for perfect adaptation to sample requirements. Another advantage is the so-called zero-point adjustment which helps to compensate for wear of the breaking jaws. Operating the BB 50 is simple and safe. The large hopper facilitates material feed, the capacity of the collecting receptacle has been doubled. The fold-back hopper can be easily removed without using tools, just like the crusher arm. The breaking jaws can be replaced by the user as well. The space-saving unit fits on any laboratory bench and crushes smaller sample volumes with a feed size of up to 40 mm to a final fineness of approximately 0.5 mm, depending on material properties. There is no other instrument in the market to achieve this in a single operation! Breaking jaws and wearing plates

Laboratory mill with autofill system for LN2 For size reduction of sample materials which cannot be processed at room temperature, RETSCH’s CryoMill is the ideal choice. An integrated cooling system ensures that the grinding jar is continually cooled with liquid nitrogen before and during the grinding process. Thus the sample is embrittled and volatile components are preserved. An Autofill System provides liquid nitrogen in the required amount so that the user never gets into direct contact with the LN2 which makes operating the mill particularly safe. The new CryoMill achieves considerably improved grind sizes thanks to the increased oscillating frequency of 30 Hz. Another new feature is the possibility to store up to 9 SOPs. Further improvements include a reinforced housing, optimized liquid nitrogen duct and new accessories such as an adapter for 6 reaction vials and a 10 ml grinding jar. The mill can also be operated without cooling which makes it suitable for a vast range of applications. NEW: • Oscillating

Dinnissen develops system for petrochemical industry Thick, highly viscous residual waste flows from the petrochemical industry that may also be contaminated with hard objects are very difficult to process. Because this residual waste often contains valuable pure metals, Dinnissen has developed a new purpose-built recovery system. The system covers the complete process from emptying the drums, containers or big bags right up to final packing of the purified metals. Special grinding unit processes residual waste into a homogenous material Certified waste flows from the petrochemical industry which are both highly viscous and contaminated with wood, stone and iron particles were almost impossible to process until recently. However, Dinnissen has now developed a new technology in order to recover precious metals such as chrome and molybdenum from this material. The thick, viscous tar mass (from drums, containers and big bags) is placed in special tipper units. The tipper units are vibrated and shaken vigorously in order

with RETSCH”s Vibratory Disc Mill RS 200 For the rapid size reduction to analytical fineness of hard, brittle and tough materials, the new Retsch Vibratory Disc Mill RS 200 is the product of choice. The new model grinds samples such as minerals, cement, concrete, soils and also electronic scrap not only extremely fast but also with excellent reproducibility. The new features include: • Optimized drive kinematics: The main directional movement of the drive train is secured in a plane which prevents the jar from gyrating or tumbling. This leads not only to increased reproducibility but also to an extremely quick formation of the movement pattern inside the jar and thus to very short grinding times. • New operating concept: All grinding parameters can be set via one single button, the current settings can be read off a graphics display. For the RS 200 up to 10 parameter combinations can be stored. • Improved grinding sets: The grinding set geometry was further optimized to increase the

Quick and gentle grinding RETSCH’s powerful and versatile ZM 200 offers the ultimate in performance and operating comfort. It is used for the rapid size reduction of soft to medium-hard and fibrous materials down to 40 microns. Because of the efficient size reduction technique and the comprehensive range of accessories the ZM 200 ensures the gentle preparation of analytical samples in a very short time. For applications which require an optimum air throughput (e. g. heat sensitive materials) or if larger sample volumes need to be processed, the use of a cyclone is recommended. RETSCH offers a re-designed cyclone with improved functionalities for collector volumes from 250 ml to 5 liters which adds to the ZM 200’s great flexibility. Thanks to the wide range of accessories with different rotors, ring sieves and collectors, the ZM 200 can be easily adapted to suit a wide range of applications such as, for example, heavy-metal-free grinding, size reduction of abrasive materials or processing

RETSCH ‘s new 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. The provided sieves guarantee an optimum particle size distribution so that it is not necessary to recalibrate the NIR spectrometer. The rotor speed can be adjusted in 3 steps allowing for perfect adaptation to the sample requirements. Cleaning the mill is quick and easy as the air jet effects a complete discharge of the material from the grinding chamber. This new cyclone mill in proven RETSCH quality optimizes the reproducible sample preparation to NIR analysis thus allowing for meaningful and reliable analysis results. Advantages: • Ideal for grinding feeds, grains, forage and similar
