► © BMA AG Subject to technical modifications 05/2014 newsletter Dear Readers, BMA has been active in the sugar industry for more than 160 years. We have provided support and advice to many of our customers for decades, in projects to increase plant capacity or improve efficiency and quality. This has included consulting work for engineering projects and investment planning, as well as the supply of equipment and services. Customers have repeatedly told us that the exceptional reliability and performance of our equipment and BMA’s technological expertise are essential criteria in opting for equipment made by BMA. We are delighted that you have every confidence in us and wish to thank you very much for the continuing close collaboration. Kind regards Uwe Schwanke Member of the Board P.S.: Thanks to an optimisation of our internal processes, our centrifugals now have much shorter delivery times – please contact us to find out more! Separate installation of a centrifugal and its operator panel in the sugar factory at Bury St Edmunds BMA News May 2014 British Sugar invests in K3300 The Bury St Edmunds sugar factory commissioned another six continuous K3300 centrifugals during the 2013 juice campaign, so its B and C products are now exclusively produced by K3300 machines. This type of centrifugal is perfect for the processing of B and C product, as well as for B and C affination. Bury St Edmunds is delighted with the excellent performance and efficiency of the centrifugals, resulting from the two-stage basket and the Turbo3 product distributor. Further assets are the long service life and the simple maintenance; all these were decisive arguments for converting the overall production and affination of B and C products to K3300 centrifugals. The standardisation of this part of sugar production will considerably simplify spare parts management. British Sugar particularly appreciates BMA’s ability to respond to special requests. During manufacture, additional customersupplied vibration sensors were installed in the K3300 machines. There is an increasing number of customers, whose safety regulations include type-specific sensors, which they wish to have installed. Due to space restrictions, the operator panels could not be attached directly to the machines, and an alternative thus had to be found: they were positioned separately, opposite the centrifugals. The period available for installation was very short, since the beet campaign ran until the end of March and the juice campaign started already at the beginning of May. But thanks to the plug-and-produce concept of the K3300, an entire station can be assembled within a short time. The K3300 machine is supplied including piping ready-foruse and only needs to be connected to water and steam supplies. Belarus continues to invest in modern extraction plants To date, the factories at Slutsk and Gorodeja have been using two DDS trough extraction plants of an older design, with nominal beet processing rates of 2,000 and 3,000 t/d respectively. These equipment components were very excessively operated during the past years and reached their performance limit. The decision was therefore taken to replace the technically outdated DDS trough extraction machines by proven BMA extraction plants. BMA-made extraction plants with a nominal beet processing rate of 10,000 t/d were successfully commissioned at the Slutsk and Gorodeja factories. BMA supplied identical equipment components for both factories, except for the peripheral equipment, such as pumps, heat exchangers and sand/juice separators. …/2 The countercurrent cossette mixer (6.7 Ø x 8.5 m) and the extraction tower (9.6 Ø x 22.73 m) are the core The automation components. concepts were implemented in different ways at the two factories, since Slutsk uses an Allen-Bradley control system, whereas Gorodeja works with an ABB control. Once the BMA extraction plant tower had been built, the factory staff had to get used to a different way of plant operation. BMA assisted in the training of the operating personnel during commissioning, which helped realise a quick changeover. Given the positive experiences made at Slutsk and Gorodeja, the Skidel sugar factory also decided to replace their extraction machinery with a modern extraction tower. Extension of the refined-sugar VKT in Malaysia In 1996, BMA had delivered a refinedsugar VKT with a throughput of 80 t/h to Malayan Sugar Manufacturing Co. Bhd. (MSM) in Malaysia. What is special about this VKT is that it is partly heated with the vapour from the batch pan (DVK). The heating steam for the VKT comes from a thermal vapour compressor that is driven not only by the DVK vapour but also by motive steam. This allows considerable steam savings. Now there are plans to increase the throughput of the refinery and thus of the VKT. Since the driving temperature difference between heating steam and massecuite cannot be altered with the existing conditions, a throughput increase can only be achieved by extending the heating surface. BMA has therefore suggested mounting another calandria on top of the existing VKT. The foundation and the statics were originally designed for a possible extension, so another calandria can be top-mounted without any problems. The actual challenge in this extension is the coordination of the work to be done. As the existing VKT is operated all year round, with only short interruptions, the extension work has to be scheduled in such a way that preparations for the extension work are made during these short interruptions, and the work is performed during running operation and without impairing the process. Owing to the very good teamwork between MSM and BMA, it was possible to identify potential obstructions in advance and find solutions for implementing the extension without interruption. Commissioning of the VKT with a throughput of 100 t/h is scheduled for summer 2014.
