TM used less power to produce a product 65µm or smaller compared to the Tower Mill. This means for this magnetite feed, an operator targeting a product of 40µm with an IsaMillTM will need approximately 14 to 18Kwh/T, while a Tower Mill will need a lot more energy between 26 to 27Kwh/T. The implications for this is smaller installed power for an
