An energy based comparison of vertical roller mills and tumbling mills
The vertical roller mill equipped with an internal classifier is often said to be more energy efficient than tumbling mills working on the same material and the same size step (e.g. Gerold et al., 2012). It is long established in the cement industry and gains more and more importance in the industrial mineral and iron ore sectors.

Ball Mill
The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.

Regrind of metallic ores with Vertical Mills
The specific energy consumption measured in the Vertical Mill was 9.7 kWh/t, while in the ball mill it was 11.2 kWh/t. It is important to note here that the ore that feeds the Vertical Mill has a higher WI than the ore that feeds the ball mill. The Vertical Mill uses a magnetic liner and the maintenance crew did not report any significant problems.
