A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles

ABSTRACT A review is made of the methods and theory of measurements of residence time distributions (RTD's) in mills. Literature data on RTD's is assembled. The mean residence times indicate that some industrial mills are operated in the over–filled condition, leading to poor breakage conditions. Although all RTD's are somewhat similar on a dimensionless basis, there appears to be no

The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the results.

This allowed the application of the AR methodology to be extended to a full-scale ball mill. Then a link was established between residence time to mill product specifications for a given feed size. The findings showed that the residence time required by a full-scale mill falls between those at which the fully mixed and the plug flow mills operate.
