power consumption in ball mill - the-specialists mill is the energy consumption. The power supplied to the mill is used primarily to lift the load medium and charge. Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8 .
Apr 24 2015 5. The ball mill is used for grinding materials such as coalpigmentsand fedspar for pottery. Grinding can be carried out in either wet or dry but the former is carried out at low speeds. The advantages of wet grinding are less power consumptionincreased capacityno dust formation etc. Dis advantages are high wear on the grinding medium .
Total power consumption for grinding circuit as a whole is also less by about 30 compared to closed circuit ball mill in spite of higher fan power. Feed size can be as large as 75 to 100 mm. Feed size can be as large as 5 of roller diameter.
