In various reference applications, Gericke Nibblers are used for the preparation of bulk material to ensure a reliable process. Nibbler reduce the size of agglomerates, lumps or hard blocks into the initial particle size without heating up the product. Dust creation is minimal. Nibbler work with low tip speed and can therefore be used for fragile and temperature sensitive products. The Gericke Nibbler is supplied into different ATEX zones. Typically, Nibblers are placed after sack tipping units, container or big bag emptying stations. Used for recycling of non-conform batches they help to reduce the material cost for production. Nibbler screens are available with holes varying from 1,5 up to 25 mm. Larger Nibblers with inlet sections from 300x450 up to 300x800 can be used after filter presses mounted on mobile frames in order to adjust the size of the filter cakes. New!

The economic response to European Parliament Directive 2003/53/EC The above Directive specifies that as of the end of 2004 cement and cement-containing preparations must not contain more than 0.0002 % (2 ppm) soluble chrome-VI since that can cause severe allergic reactions when in contact with the skin for longer periods. Hence, over 350 cement plants throughout Europe had to be upgraded in a hurry. Iron-II and tin-II sulphates reduce the chrome content. With re-ducing agents and water chromate-VI is converted into antisoluble chromate-III hy-droxide harmless to the skin. 0.3 to 0.5 % tin/Fe(II) sulphates must be added. The MechaTron®, designed for 0.5 to 600 t/hr, offers all requisite properties. There are different MechaTron® variants available, depending on material properties and feed rates. For the sluggish Fe(II) sulphate there is the Coni-Flex® variant with flexible dis-charge hopper, for the even more difficult to handle tin sulphate Coni-Steel® with in-ternal agitator is the choice. MechaTronâ systems,

Level detection in Silica Acids A specially demanding task concerning the sensitivity of measuring equipment, is level detection in silica acids. The material changes its density very much according to how it is handled. The density of around 500 g/l when in a passive state can easily turn to less than 5 g/l when operated, e.g. during metering, pneumatic conveyance, emptying of containers etc. - the surface of the silica acid can suddenly resemble a seething cloud. The new electronic module developed by UWT is so sensitive that the material is detected absolutely reliably, in spite of the very low dampening effect caused by the silica acid on the vibrating fingers of the probe. An immediate output of the level limit signal is guaranteed. From the well proven VIBRANIVO model range of units UWT is offering two additional models: the Vibrasilâ70 and Vibrasilâ90, which are also available with PFA-coated oscillator, depending on the area of application. UWT Level control – simply working

HERBOLD Meckesheim has designed a compact line for the treatment of toner cartridges. This system has been built and recently delivered to a company in Southern Germany. Using a belt conveyor with a hydraulic pushing device the material is transported to a first shredder where the material is coarsely size-reduced. If necessary, metals can be discharged at this step. Afterwards the material is fed to a slow-running HERBOLD granulator of the SML-LS series which, due to a low circumferential speed, will provide the final granular size of the material. With the help of a spiral conveyor the material is transported to a screening machine where the toner dust developed during size-reduction will be separated from the ground material. Since toner can provoke dust explosions, the machine has been equipped with a corresponding surveillance device. The received size-reduced material can easily be reused for injection moulding applications. The advantages of the plant: All

Press Agglomeration of Corrosive and Abrasive Materials Fine dispersed bulk materials are processed with roller compactors to hard flakes and briquettes. Extremely abrasive and corrosive Products cannot be processed with usual materials of construction. Wear and corrosion create metal removal at the press rolls and other contact parts and result in high process cost and contamination of the products to be processed. In order to improve the service life of the equipment but also to work with low or totally without contamination, new materials of construction have been developed and are now successfully used in production plants. Conventional protections against wear can bring the cost to a reasonable level, but contamination in the range of ppm is still a problem. The efficiency of semiconductors and refractories can be considerably reduced. A matrix for the selection of the most adequate materials of construction is now available. Some examples are hydrocarbon coatings, plasma surface coatings and ceramic materials. These

The end of pick and shovel work as we know it! Emptying BigBags, Bulk bags and Oktabins by means of suction from above – a method never considered possible before – is now enabled with this new system! The Helios OKTOMAT with fluidisation system masters the art of 100% automatically emptying non free flowing bulk materials such as pressed screen waste, foils to be ground and pure glass fibre. Helios’ latest development now enables the automatic emptying and subsequent conveying of the problematic bulk material whereas, once, this task could only be performed by means of “pick and shovel work”. The profession is delighted. This innovation will be on display at the Fakuma 2005, hall A3, booth 3215.
