HeidelbergCement’s UK division, Hanson Cement, has achieved savings of some £86 000 per year in electricity costs at its Ketton cement plant in Rutland through a clinker cooler upgrade. The project, carried out by Siemens, used variable speed drive technology to reduce energy use and noise levels, also resulting in a 771 t reduction in CO2 emissions.
Six G150 converters with enhanced energy-saving functions have been installed with insulated bearings fitted to the existing motors.
Electrical engineer Trevor Jibb is delighted with the upgrade: “The significant energy savings we’ve already made, coupled with the reduction in carbon footprint mean that Ketton continues to be a great example of best practice within the HeidelbergCement Group, and the industry.“Thanks to the significant improvements in efficiency, the company has achieved a return on investment in just over a year and will continue to make savings into the future.
