    5 hours ago · With depleting metal ore reserves and finely dispersed ore bodies, fine grinding has become an integral part of mineral processing circuits. In the past seven years, Outotec HIG mills have been marketed, tested, sold and commissioned for a number of projects worldwide in a wide range of applications and mill sizes, including the world s highest power regrind / fine grinding / stirred mills. Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
