In fact, in the same application a Vertimill has 50% less footprint than a ball mill. Lower operating cost. Vertimill is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency. The operating variables considered are mill speed, ball load, particle load, ball diameter and mill diameter. The materials studied are quartz, limestone, dolomite and two types of cement clinker. Important findings are described below In general, both the performance parameters vary significantly (20-40%) with the mill operating variables.
