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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

2007-04-30· The rougher spirals produce a concentrate averaging 10-15% heavy minerals. The rougher tailings discharge into the pond as backfill. Since 96% of the dredge feed is returned to the pond, the dredge and pond actually move slowly forward in the direction of the mining. About every two weeks, it is necessary to move the floating wet mill to keep up with the advance of the dredge.

These wastes can be subdivided into a number of categories: waste rock, mill tailings, coal refuse, wash slimes, and spent oil shale. The mining and processing of mineral ores results in the production of large quantities of residual wastes that are for the most part earth- or rock-like in nature.
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh
