Running Tracks made from Old Tyres 13.5 million tons of old tires per year are accumulated worldwide, • 4.4 million tons of which in North America, • 3.4 million tons of which in Europe, and • 5.7 million tons of which in the rest of the world. In Germany, 650,000 tons of old tires are accumulated per year, around 50% of which are used as secondary or substitute fuels in cement plants. The other 50% are split up into their components: • rubber 67% • steel 19% (melted down in steel works) • textiles 14% (used as substitute fuel). The rubber is crushed and processed as granule or rubber powder. There are two main processing options: on one hand the modification of bitumen and asphalt, on the other hand the production of rubber tracks or rubber sheets. The latter are used, among others, for footfall sound isolation beneath floors, as injury protection ground coverings for playgrounds, as indoor sports mats , or as outdoor running tracks. The running track in the Berlin Olympic

ideal for grinding of tablets, dragées and pharmaceuticals The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 grinds rapid and effectively soft to medium-hard, brittle as well as fibrous samples. Even the comminution of samples, which are difficult to grind or temperature-sensitive samples like tablets, dragées and pharmaceuticals are no problem for the PULVERISETTE 14 due to its very efficient air cooling. In addition to the special air cooling of the PULVERISETTE 14, we have developed the FRITSCH-impact blades: Due to its clever design it allows together with a sieve ring a very gentle grinding of the sample, which in many cases without impact blades would not be possible. The result: Increased grinding action for a particularly fast and effective grinding, the heat load is minimized. And the ideal solution for especially temperature-sensitive materials such as powder coatings or plastics, as well as for smoothly pre- and fine grinding of hard-brittle to soft, fatty sample or samples with a residual moisture!

SMC, the world’s leading pneumatics provider, has unveiled an upgraded version of its CRB2 Series vane type rotary actuator. In addition to the double shaft, the updated CRB2-Z features a single shaft as standard and provides easier piping due to the parallel location of the ports, which can be side or axial ported, demonstrating SMC’s commitment to improve the performance and functionality of its products. Available with four rotating angles ranging from 90° to 270°, the CRB2-Z is ideal for applications within tight spaces as well as robotics and material handling. Heavier loads are also catered for thanks to the double vane type which has twice the torque capacity of the single vane option but with the same dimensions. Offering flexibility, the CRB2-Z has the optional use of an auto switch unit – in which the auto switches can be secured in any position in the circumferential direction – and / or an angle adjustor unit, both of which can be directly

Approvable and versatile intake- and out-loading scale for bulk material With experience from more than 100 delivered intake scales, as well as a vast experience in weighing solutions in general. Jesma Weighing solutions from Vejle in Denmark has developed a complete program of intake scales specially designed for in-line weighing of bulk materials such as powders and granulates with focus on operational reliability and accuracy. The JesHopper Intake can be used in many industries from grain and feed milling to more heavy duty industries like e.g. the cement industry. The JesHopper intake can be used for raw material intake, in-line weighing in places were accuracy is very important as well as weighing the finished products into big bags. In this way the same technology can be used throughout the production making it easier for the employees to maintain and service the equipment. The JesHopper Intake can be set up for up to 400 weighings per hour and with capacities up to 900 m3/h. The smallest intake scale from Jesma has a max.

To meet the demand for rotary valves with a larger capacity, VDL Industrial Products has introduced the HT-450.

The HT-450 has a gross capacity of about 35 liters/revolution and combines simplicity and ease of maintenance with robustness. This valve has a cast iron housing and is equipped with a rotor with 8 chambers, ball bearing shaft and a direct-mounted flanged gear motor. By default, the HT-450 rotary valve is equipped with a steel rotor with steel or Vulkollan blades, a gear motor 1.1kw with 25 revolutions/minute, brand: NORD or SEW and is painted in the colour RAL 5009. Also in this new model, we offer tailor-made options and versions, such as various treatments of the housing and different drive possibilities.

Short clamping times increase machining efficiency for workpieces These days it is common for robots to be deployed in the production of high quality workpieces. A clamping device is required to hold the components firmly in place ready for machining. However, when using a conventional palette storage system the machining steps can be carried out only in a fully automated process. Then, production flow is held up if components need turning or if clamping jaws - even entire fixtures - need to be changed. This is where ROEMHELD, the well-known specialist in clamping technology, can help. At EMO 2013, the international trade show for production technology, the company presented some very well received clamping solutions for automated workpiece processing - solutions that can be implemented sustainably from the smallest of batch sizes. QUESTION: Over the past 20 years international usage of machine tools has risen by 70 per cent. Half of all such machines come from Europe alone and are supplied to more than 70 countries. These are figures

The comprehensive application know-how of MBA Instruments GmbH Quickborn, 1. June 2013 Direct drive without gearbox, powerful motor with miniature paddle, selectable pre-set parameter combinations for universal use - these are the main features of the new series of rotating paddle type version MBA800 for level measurement. The idea is old, but it has never been implemented yet. The inspiration for implementation of these ideas was the MBA-owned patent for magnetic coupling (patent no.: EP1357366B1). By now, the idea of the magnetic coupling has now been developed as an integral component in permanent magnetic synchronous motors. Due to the direct drive variable-speed motor control, parameters can be coordinated in such a way that the various functions of the machine can be adjusted to the different types of bulk goods and their characteristics in the relevant application. These pre-set parameter combinations are what make the MBA800 unique in the world to date. It has already proven its worth excellently in field tests. Combination

Automation and instrumentation for material handling from a single source Quickborn/Litauen, September 2013 – The Klaipeda Stevedoring Company (Klasco) in Lithuania is continuing to invest in the expansionm of its material handling capacities: A further high-performance, ultramodern ship loader has been ordered for the loading of fertilisers at its deep-water quay from the German SMB Group with headquarters in Quickborn near Hamburg. „We expect to commission the ship loader in Lithuania in December 2013,“ announced Andreas Heckel, Managing Director and CEO of the SMB Group. SMB delivered the first ship loader to Klasco six years ago. „It has done outstanding service there,“ added Heckel. „Although – at the customer‘s request – the first ship loader was designed for only one to two-shift operation, it has operated practically 24/7 over the past two years due to the sharp increase in fertiliser trans-shipment figures. And that without any problems.“ Added to that were the enormous loads as a result of extreme temperature

Efficient utilisation of waterways with ship loaders by SMB International Quickborn, June 2013. Utilisation of waterways is a cost-efficient transport alternative, particularly in countries with poor infrastructure. In order to reach remote inland harbours without having to reload the freight, smaller ships are loaded from the beginning. The prerequisite for this type of cost-effective transport is to perform loading of the ships fast and safely and to exploit the entire freight hold available. And it is SMB International who provides an optimum solution particularly for these tasks. For more than 20 years, SMB has realise more than 80 ship loading systems in many countries - our international references range from Western Europe and Russia to Latin America and even South-East Asia. Loading systems for ships from 5,000 dwt to 90,000 dwt (dead weight tonnage) have been developed and built, regardless whether a stationary loading system is used or whether mobile loading systems travel back and forth on rails along the quay wall. the faster

Energy efficient level indicators for bulk solids applications The request of many customers to save energy in their production processes can be realized not only with high end sensors but although with level indicators that enable a reliable and price worthy level measurement without any power supply. The level indicators of the MOLOSmembran series of MOLLET exactly meet this requirement and are used from satisfied customers worldwide in the applications storage, transport and processing of bulk solids. The MOLOSmembran level indicators of MOLLET are mechanical switches for bulk solids with a bulk density from 0.3 to 2.5 g/m³. As soon as the bulk material reaches the sensor, the signal is switched by the pressure of the bulk material on the membrane. All components that are in contact with the product like mounting ring or membrane are available in a stainless steel version. In case this is not needed, cheaper materials like a Viton-membrane or mounting rings made of Zinc-plated steel can be ordered. The housings are alternatively

Using the newly developed flow sensor it is possible in harsh production environments, to measure th The FlowChecker combines low investment costs with a simple operation and quick readiness for use. Special attention was paid to the ease of operation and calibration of the system, so it can be independently carried out by the customer, without support of RHEWUM. The measuring system FlowChecker consists of a highly developed 3D TOF sensor, an industrial PC and analyzing software, which calculates the mass flow or volume flow of the determined data. Additionally, the output (volume or quantity) will be calculated and displayed. The result will be logged electronically. For embedding in existing systems, the FlowChecker is equipped with a network connection (TCP-IP) and an interface to OPC servers.

The latest addition to the ProFi product line is the stand-alone filter system ProFi-Clean The newly developed and patent-pending "ProFi – Clean" filter is easily installed by a clamp connector as a module on the milling chambers or Inlets/outlets housings of all Frewitt mills (OscilloWitt, HammerWitt, ConiWitt, and TurboWitt). Sieve mills in existing systems can be retrofit in a few simple steps. Numerous advantages set this filter system apart from others. Low-pressure filling Exhaust air at atmospheric pressure escapes from the milling chamber via the filter, which traps any product. To prevent product build-up on the filter, the exhaust air filter is cleaned by a time-controlled pressure surge (shown by the blue arrows in the drawing). The advantage of this method is that continuous, uninterrupted product filling is possible. The product is fed back into the process by means of the exceptionally efficient pressure surge cleaning. Dust-free atmosphere Particles > 5μm can be filtered out, thus fulfilling the requirements for
