The transmission drive for main rotary kiln at Rugby Cement’s Barrington (UK) works had an open lubrication system. Oil was spray fed directly onto the gears. Unsurprisingly fluid analysis revealed substantial contamination, indicating wear to the pump and gear teeth. The lubrication system had been accumulating and re-circulating damaging debris.
Fitting a Magnom Inline Process Unit quickly reduced the risk of failure by removing 2kg of contamination in the first week alone, including large (5mm+) particles. Particulate level, even in an open system like this, was reduced to fewer than 5 microns.
