Optimization of mill performance by using

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


Optimal mill loading with LoadIQ | FLSmidth

LoadIQ utilises our mill scanner smart sensor technology to accurately measure volumetric filling and ore trajectory in real-time. It then combines this reading with data about the ore type and liner profile to determine the optimum mill load. Mill operating parameters are then automatically adjusted in real time as grinding conditions change.
