Here we will give you a complete guide on what is a ball mill vs SAG mill, how they are different, and how they are used. Let's get started! Operating Principle. The operating principle difference between a ball mill and a SAG mill is their specific energy consumption. Ball mills use an induced storage mechanism to grind materials.

The effect on overflow ball mill power draw of the minor changes attributable to the increased feed rate may be different to that on an AG/SAG mill. For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw; rather more often the opposite.
