Tumbling mills are notorious for their low energy efficiency because they only use up to 10% of installed power for grinding action. A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity,, during the grinding of material.

Historically there has been three basic ways of grinding ore, hammer mills, rolls, or wet tumbling mills. Hammer mills and rolls are not used that often and then usually only for special applications as in lab work or chemical preparation. The type of mill that is used for grinding ore in a modern concentrator is the wet tumbling mill.

Abstract. The discrete element method (DEM) is a proven numerical technique for modelling the multibody collision behavior of particulate systems. This method is used here to study the motion of ball charge in tumbling mills. To get meaningful results, it is essential that the parameters involved in the model be carefully determined.

However, the low grinding efficiency of rod mills limits their wide application, especially for ores with high Mohs hardness. Grinding media including short cylinders, truncated cones and hexagons, etc., possessing two or three contact modes (point, line or surface contact modes) with minerals, which can avoid overgrinding, increase the production of particles with intermediate sizes and ...
