The stirred mills, recently introduced to mineral processing, have proved to be more energy efficient than tumbling mills in terms of fine grinding, and have been extensively used in many mineral processing plants at the regrinding stage (Gao et al., 2002, Jankovic, 2003, Pease et al., 2006). In contrast to tumbling mills, where motion is ...

These days, regrinding is becoming increasingly common due to the need to process more and more low grade and complicated ores. Regrinding not only further reduces particle size and increases the liberation but also produces new surfaces and changes the pulp chemistry, both of which are critical for subsequent flotation.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Based on the crushing theory, increasing the amount of regrinding sand does not increase the power consumption of the mill, but only speed up the slurry flow. In addition, thick and coarse regrinding speeding up the slurry flow can make the coarse grain distributed more evenly, thus improve the steel ball grinding performance and efficiency.
