Introduction. Grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]].

grinding. A material grinding process in ball drum mills is executed by grinding bodies that move in a transverse section of a mill drum. Besides, only 50% of grinding bodies grind a material, and the remaining 50% are dead zones do not grind a material. An intensification of grinding media movement enables to improve an efficiency

The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.

To calculate the embodied energy, media use data was obtained for 34 individual mills in addition to 27 comminution circuits. The total comminution energy for these mills was then calculated by combining the total electrical energy and the equivalent embodied energy (assuming forged balls) consumed through media wear (see Figure 1).In relation to the electrical energy consumption, SAG mills ...
