Vertical Roller Mills (VRM), High Pressure Grinding Rolls (HPGR), Vertical Shaft Impact Crushers (VSI) and more recently, Horizontal Roller Mill (Horomill) have saved the specific power by 4570% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.

The table roller mill is a robust and reliable mill suitable for processing mediumhard mineral raw materials. For many years, however, the fineness range of these mills was limited to end products not finer than d 97 = 40 60 µm. This was attributed on one hand due to the lack of a modern classifying stage and on the other

The increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for improvements in power consumption and performance.
