May 08, 2012 Roller mills are more energy efficient than hammer mills when grinding friable materials; the advantage for corn is 5% at sizes smaller than 500 microns, becomes 25-30% at 800 microns, and increases to perhaps 80% at a size of 3000 microns (CPM, 1992). The hammer mill (Figure 4) remains the industry standard for size reduction.

Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major ...
