Grinding Trends In The Cement Industry Cement Lime

Summary The main trends concerning grinding processes in the cement industry are still higher efficiency reduction of the power consumption and system simplicity In the case of new orders vertical mills have increased their share to over 60   and ball mills have fallen to less than 30  .CGA are adsorbed on the newly created surface neutralising electrical charges and thus reducing their tendency to re agglomerate Hence the cement grains show a lower resistance to comminution These provides benefits to grinding efficiency by Reduction in agglomeration and coating of the mill internals.
