Regrinding ArchivesBall Mills and stirred mills are applied across a wide range of appliions, but for each ore there is optimum efficient range. The figure to the left shows the typical appliion ranges for ball mills and stirred mill. The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to . Read more
Effect of regrinding conditions on the flotation of sulphide minerals .It not only reduces the particle size and improves mineral liberation but also modifies particle surfaces and pulp chemistry due to the strong electrochemical reactions taking place during regrinding. Therefore, the floatability of minerals in the subsequent cleaner flotation is influenced by the regrinding conditions.

Outotec HIGmill(TM) · The Outotec HIGmill offers a great advantage for concentrators that are aiming for improved grinding efficiency or require regrinding in their process. HIGmill technology has been developed and utilized for more than 30 years. Today there are more than 260 installed units around the world, with installed mill power up to 5,000kW.
Stirred Milling Technology – A New Concept in Fine GrindingWith the grinding media evenly distributed, the ore particles remain in constant contact, significantly increasing grinding efficiency. Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (NapierMunn et al., 2005).
Ore Processing | MultotecMineral Ore Processing Ore processing is a chain of processing appliions which treats run of mine to firstly highgrade concentrate (concentration of ores) and then to the pure mineral or metal. The refined ore is used in manufacturing equipment and machinery in numerous industries, or is for sale in industry, commerce and consumer industries.
Stirred Milling Technology – A New Concept in Fine GrindingApart from a finer grind, energy efficiency is also a key driver in optimising comminution technology. Stirred milling technology, already proven in many other industries, delivers a modern, sophistied, flexible and energy efficient grinding solution for fine and ultra fine grinding in minerals processing.
