Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Kolacz (1997) proposed a method to measure the fill level by using a strain transducer. The transducer was installed at the middle of the mill shell. When the transducer moved to the top position of the mill shell, it measured the compression. After half a revolution, the transducer reached the bottom of the mill shell, the tension being measured.

Generally, traditional ball mills are divided into two chambers and use vibration or noise sensors to measure the fill levels of these. Besides, there is the monitoring of the current and power of the mill main motor, since these parameters also indicate the mill fill level. As the mill rotates, the movement of the balls grinds the

The MillStar Power Optimiser: Continuously "seeks" for the optimum mill operation by changing the solids feed or load setpoint. Uses the changes in the mill load and power to automatically detect whether the mill is overloaded or underloaded. Uses safety controllers to change the solids feed rate and feed water to prevent mill overloads.

Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly. This mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.
