Separator is compliant with all recent safety food standards


T


he new generation separator increases safety and improves clean-up and maintenance as it provides a standard


global presence for the traditional round separator. The totally enclosed weight guard prevents


‘reach-in’ injuries and complies with European CE Standards. This MX design also complies with ATEX Standards by making use of the appropriate motor, conductive gaskets and anti-static spout connectors all applicable for the Food industry as well.


The open base construction allows for


cleaning underneath the unit, therefore preventing dirt and product build-up to occur. Additionally, the MX base design eliminates all gussets and external crevices where product can become trapped while allowing for total external polishing of the machine. These features allow for a more sanitary designed separator. The open


construction scheme also allows for easier inspection and cleaning of the separator’s underside. Angled support springs


minimise aggressive vibration that typically occurs during shutdown of the machine. The extremely


rugged construction of this machine utilises conical construction rather than flat plates which creates a more rigid geometric structure. This concept has been successfully tested and proven through millions of high G life cycles. The choice for special noise abating metals and self cleaning screens with larger sliders have a positive influence on the noise levels of the separator. Noise reductions can be measured as much as 16dbA.


Aqueous coalescing now effective and cost efficient


T


he goal was simple: demonstrate both low cost and effective coalescence of entrained organic to improve


performance of dual-media filters; and provide a standalone solution for raffinate. SpinTek Filtration met this goal through


the creation of its new aqueous coalescing technology, the Aqualescer, a pre-treatment of organic in Solvent Extraction (SX) plants for hydrometallurgy applications. This system improves coalescence by adding pressurized air in the inlet feed line, increasing efficiencies. A test conducted in South America at the


Gaby Copper Mine’s Solvent Extraction (SX) Plant offered the opportunity to use the new Aqualescer in conjunction with the CoMatrix SX system to evaluate the removal of small organic droplets and crud from the raffinate stream during service operations. The results showed low levels of organic in


the total effluent with the vast majority of organic removed by the Aqualescer.


With organic inlet concentrations as low as


9ppm the average entrained organic removal was 75 per cent. Efficiency removals rose to 88 per cent


when the organic present in the feed was greater than 20ppm. The success of this test program led to the


sale of the first-ever combined Aqualescer and CoMatrix system in Central Asia. This system is under construction at Central Asia Mining, a SX copper mine in the Republic of Kazakhstan SpinTek has been manufacturing proprietary industrial filtration systems and tubular membrane filtration modules formore than 14 years. Its expertise is in membrane filtration system design and engineering of large custom filtration (media) equipment for mining filtration,. ■

Monitoring the


elastomeric materials used makes this new generation round separators also compliant with the EC1935/2004 Food Contact regulations and GMP standards. On demand of the


Food industry a lot of research has been done into magnetically reactive and FDA acceptable cleaning balls and sliders for direct food contact. In case of screen breakage specially woven magnetic screen cloth can be retrieved in the downstream process by magnets. All this makes the new generation MX Round Separator a safer, cleaner and stronger equipment that can be used chemical, food, pharmaceutical, mineral, paper, and many other industries. ■

Compact drives gain appeal


E


volving energy legislation, paralleled by the need to regulate energy costs and improve efficiency, is boosting the


uptake of micro electric drives. New analysis from Frost & Sullivan, finds that the market earned revenues of $516.8 million in 2012 and estimates this to reach $637.1 million in 2016. The research covers AC, DC and servo


micro electric drives.In Europe, motor-driven applications account for almost 65.0 per cent of energy consumed in manufacturing plants. Technological advances in


microprocessors and insulated-gate bipolar transistor (IGBT) technology have made electric drives more compact and user-friendly. This is encouraging more OEMs to use electric drives in their machines. Evolving semiconductor technology has


resulted in electric drives that are capable of withstanding high temperatures, allowing them to be directly mounted onto motors. ■
