to be used in ATEX zones 1/21 with internal zone definition 0/20 Gericke volumetric and gravimetric feeders are running on many, various applications worldwide. To comply with ATEX regulations, Gericke has undertaken, on all its feeders, a security assessment and got the necessary certificates by notified bodies. Feeders and loss-in-weight feeders can now be delivered for zones 1/21 and 2/22 outside, thus designed as equipment category 2 or 3, and category 1 for internal zone 0/20. In other words, the powder or dust should contain a minimal ignition temperature > 200°C, a layer ignition temperature of > 210°C and a minimal ignition energy of > 1 mJ. The marking can be, as an example: CE 0081 Ex II 1 /2 DG c IIC T 130°C Please contact Gericke for further information for the integration of feeders, mixers or conveying systems as well as for the upgrade of existing equipment, according to regulation 94/9 CE.

Optimal sample preparation for the RoHS/WEEE Analysis Considering the characteristics of materials used for the construction of a cell phone the whole spectrum of hard-tough to hard-brittle up to soft, tough-elastic materials is found. Mentioned should be metals, ceramic parts and the most various plastics. Whereas the hard-brittle materials are easily ground with impact energy, the comminution of tough-elastic materials is only achieved with cutting force. Tough-elastic materials may be embrittled with liquid nitrogen and then ground with impact force. The Power Cutting Mill PULVERISETTE 25 was chosen as the first level of comminution of a complete cell phone. Once reduced to 10 mm the Vibrating Cup Mill PULVERISETTE 9 was supposed to complete the rest. This experiment was unsuccessful. Therefore the PULVERISETTE 25 with a 4 mm sieve was used again. For the next level, the Universal Cutting Mill PULVERISETTE 19 was chosen. With cutting tools made of hard metal tungsten carbide the remainder was comminuted down

LUM moves location of US subsidiary LUM Corp. to Austin, TX Berlin, 23.08.2007: L.U.M. GmbH, market leader in innovative instruments for dispersion characterization, moves the location of its US subsidiary LUM Corporation to Volente, a suburb of the rising metropolis Austin, Texas. The further growth of LUM Corp. requires the expansion of the office and the strategic positioning of the central location for the distribution in North America. The move from the East coast to Austin follows the trend of the high-tech companies to settle in southern or western parts of the US, and enables a better service to all customers across the NAFTA region. LUM is now closer to the growth market Mexico, too. Furthermore, the technology and growth oriented environment in the Silicon Hills of Austin influenced the decision, several industrial key accounts from the high technology sector are close by. Prof. Lerche, President of LUM Corporation: „Last but not least we decided for this site to meet the increasing demands for our products from

Errors in sample preparation, above all in dividing the laboratory sample, accumulate in the course of the process and cannot be compensated, even by the most up-to-date analytical instruments. Only the exact division of the entire sample into representative fractions will guarantee exact and unbiased analytical results! RETSCH offer a range of instruments for the representative sample division of bulk materials which operate with different functional principles. Scientific investigations have proven that rotating rifflers, such as RETSCH’s PT 100, are the most accurate systems. Inhomogeneous samples up to 5000 ml can be fed to the PT 100 via the Vibratory Feeder DR 100. After the division, the composition of each fraction of the sample corresponds exactly to that of the original bulk sample. This is a crucial precondition for meaningful and reliable analysis results. The benefits of the PT 100 at a glance: · Extremely high division accuracy · Modular design · Extraction

A wide range of options Users can choose from three application levels, a variety of resolutions, a large selection of interfaces and other options. This adaptability makes Signum ideal for virtually any use, from simple weighing to demanding applications. The display and control unit can be set up within minutes for optimum ergonomical use – whether next to the weighing platform, on a column, or mounted on the wall. Optional interfaces Optional interfaces meet all the requirements for state-of-the-art data transfer, including Ethernet and PLC connectivity. Any of the models in this series can be fitted with an optional analog/digital converter for a second weighing platform, such as a reference scale or bulk weigher. Overload protection Signum scales not only have high overload protection, they are also extremely rugged and resistant, and adapt well to virtually any conditions in industrial use. ATEX Signum scales are available for use in zone 2 and

Customer-oriented problem solution by individual process equipments Recently a customer turned to the Telschig process engineering GmbH, Murrhardt, because he wanted to optimize the transport of its coarse-grained feed with silo cars. By the employment of an aggregate with filter inset, the particularly selected tools and operating conditions it was possible to get a grain size of 0 - 2 mm by a high throughput performance. The customer was convinced of the simple handling of the processor and of the reached process result and think about further applications for the different materials and crushing allpications. The lump breakers of Telschig process engineering GmbH are used for more than 30 years in the most different ranges of the industry. The processors works successful in chemistry, the food industry, feed production, in power stations and in the ceramic industry. The technical possibilities are adapted to the concrete problem. Cutting up and sieving take place in one process stage.
