The Power Consumption Calculation of a Ball Drum Mill258 Кб. Key words Ball drum mill Grinding media Material grinding Grinding efficiency media motion Power consumption Calculation method INTRODUCTION Hundreds of billions tons of rocks are finely ground in many industries like mining, chemical, energy, building.Mill power 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.
