Weingarten, April 2008. – Developed by Coperion Waeschle GmbH & Co. KG, Weingarten, the BULK-X-CHANGE® bulk materials heat exchanger manufacturer is now being used for the very first time by a fertilizer manufacturer for an inorganic product. Recently installed in a fertilizer production plant,
which now operates at an increased output rate of 60 tonnes/hour, the heat exchanger serves to cool the fertilizer following the crystallizing and drying stages. Its purpose is to prevent the formation of lumps during silo storage and hence improve product storability and handling.
The final decision in favour of the innovative BULK-X-CHANGE® was preceded by a comprehensive series of tests. A trial heat exchanger made available by Coperion Waeschle was installed and operated parallel to an existing plate cooler. For several weeks, the prospective user tested freshly produced fertilizer under all conceivable operation conditions and could not have been more satisfied with the performance given by this bulk materials heat exchanger. As the final unit in a long process chain, the BULK-X-CHANGE® makes considerable savings possible not only in respect of capital investment costs but also as regards space requirements and energy and operating costs, especially when compared with conventional fluid bed and drum industrial coolers. Moreover, the BULK-X-CHANGE® contributes considerably to a reduction of the production plant's carbon footprint. Indeed, it is precisely on account of these advantages and benefits that this high-performance bulk materials heat
exchanger is already well introduced into the plastics compounding and processing industries.
