In 2007, after a long period of investigation and test runs with the technical staffs from Bim Son Cement, the automatic pump system using Kluberfluid C-F3 Ultra for the lubrication of the open gear in the coal mill number one had officially been implemented. This is a state-of-the-art system with a Lincoln (USA) pneumatic pump placed directly on the drum which makes the drum replacement task much easier and without any contamination.
