for very thorough emptying of residues If it is important to have very high residual emptying rates, the amixon® conical mixers and mixer-dryers are particularly appropriate. Together with the patented "sliding blades", the conical base ensures residual emptying rates of almost 100%. With the "sliding blades", the mixing gear is tilted to a horizontal position. This improves removal of the product residues. Otherwise, the same requirements related to and governing the technical aspects of the process apply as have already been described for the vertical vacuum mixer-dryers with flat bases. Laboratory and Trials The Alloy and Hastelloy drying equipment in the amixon® Laboratory are already part of the apparatus manufacturer`s standard equipment. This offers a major advantage to all manufacturers and future customers interested in experimental trials: all products can be tested in their true form; it is not necessary to make use of a dummy product. amixon® mixer-dryers and reactors have hygienically

Our recommendation for all processing laboratories Our recommendation for all processing laboratories with a continuous delivery of brittle to very hard materials for batch or continuous fine grinding. The maximum feed particle size is approx. 20 mm edge length. The fineness attainable (d50) is down to approx. 12 mm (largest gap width) or 0.1 mm (smallest gap width). The maximum throughput of 150 kg/h depends on the gap setting and the hardness of the sample. The relatively large throughput enables it to be used in the pilot scale or in the small size production, for example: slag-disintegration for the reclamation of precious metals. Typical fields of application: Mining and steel industries, Ceramics, Rocks and soils, Glass, Soil research Features of performance: - reproducible grinding results through accurate gap setting (exactly 0.1 mm) - precision adjustment for setting gap - sight glass for checking gap width - centrally located toggle-type fastener for grinding chamber - divided, hinged grinding

with RETSCH Planetary Ball Mills When producing ultra-fine grinding material with a ball mill, certain stress mechanisms are necessary to ensure that the minute particles can be crushed at all. That is why ultra-fine grinding (colloidal grinding) through mechanical stress is mostly done in liquid media; moreover, it requires a high energy input and pressure and shearing forces which act upon the sample material. The RETSCH Planetary Ball Mill PM 100 meets these requirements. Thanks to the opposite rotation of sun wheel and grinding jar, the large effective sun wheel diameter and the high rotational speed of the sun wheel, the PM 100 possesses the required energy input for the production of nanoparticles. Eventually, the best possible combination of machine parameters and jar fillings determines the success of a colloidal grinding process. Above all, it is the selection of the grinding jar and the ball filling that has a substantial influence on the grinding results. Grinding jars and beads of zirconium

The future of mobile measurement acquisition The mobile acquisition of measurements through a data logger function is the task that can now be accomplished at a completely new level with the help of two new instruments. JUMO GmbH & Co. KG, Fulda, Germany, is presenting two new instruments at the Hanover Fair, as replacements for the existing portable digital thermometers that have been used in their thousands. Both versions have a sensor input for Pt100 resistance thermometers and type K thermocouples. The inputs can be set up as required, thus enabling the use of an extremely wide range of probe types. The temperature is indicated with an accuracy of 0.1% in a multi-line display. The JUMO TDA 300 has the capability to store up to 99 measurements within the instrument. Five different measurement point designations can also be assigned to these measurements. These values can then be shown very easily in the display at a later time, together with the date and time of the measurements. The JUMO TDA

... reliably prevents fire in dryers, filters and silos The occurrence of glowing or hot particles cannot be completely excluded from many processes. If ignition sources are transported into filters and silos via the extraction system or other conveying facilities, devastating fires and explosions can be triggered. By means of infrared sensors and downstream extinguishing nozzles, the ignition sources in mechanical and pneumatic conveying systems are reliably detected and extinguished before they reach plant areas at risk. For those applications in which water extinguishment is not possible or reasonable, GreCon developed special fire traps or diversion gates, which prevent the damaging effects of the ignition sources as quickly as the water extinguishment. Not only has the technical implementation of the principle “extinguish sparks before fire occurs” been permanently improved and optimised until now. A high level has been reached especially regarding the operation of the system and the documentation of alarms and

Bulkflow Technologies Inc. will present an innovative HT cooler for high temperature applications, designed for product temperatures up to 1000°C. The concept uses horizontal, water cooled tubes in a “serpentine” configuration, which prevents high local stresses and hot spots. The tube walls are typically refractory lined. As in the well-proven plate design heat exchangers from Bulkflow Technologies Inc, the product flows in mass flow, by gravity through the tube bundle. Applications for this high temperature cooler are catalysts, minerals such as alumina, ash and char from boilers and furnaces. Bulkflow will also present a paper during the BULKDAYS (see "Calendar`), a seminar held during Powtech and organized by the Bulk Academy.
