Control of ball mills. Mill Feed; The major feature for controlling grinding plants operating in closed circuit with a high efficiency separator is that the quantity of material fed to the mill (fresh feed+ separator grits) remains constant. The purpose of this is to ensure that the quantity of material in the grinding compartments is kept at a ...

Ball mill transport index control strategy. A simple ratio controller was implemented to regulate the solids content in the mill by manipulating the feed water. A calculated percent solid index is used to monitor the transport in the ball mill. A separate study was initiated to develop a measurement of this property (Bascur, 1985).
