Mar 01, 2011 Cement grinding - Cleaning of the mill diaphragm and central screen at regular intervals during scheduled maintenance and improving the functioning of mechanical flaps at mill discharge was recommended for efficient operation. To increase the mill capacity, the following recommended actions were implemented.
May 01, 2009 The efficiency of most grinding units is very low. The cement particles can coat the grinding media, can seal the armour plating and can agglomerate and form small plates which absorb the impact. The action of the grinding media within a rotating mill not only crushes the existing clinker particles, but also sharply compresses them, a fact that leads to the
