Scale Up in Sizing for Grinding Mills. Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.

Lab scale mill, 30 kW. Pilot scale mill, 75 kW, Small full-scale mill, 700 kW. The details of the methodology is reported elsewhere (Lehto et al., 2013, Junnola 2013) but the important parameters for model development were carefully measured and recorded. Mill torque and power draw were measured over a range of rpm's for most tests.

Jan 01, 2015· SAG mill power consumption (Pc) in kW, in 4 grinding circuits (GC1 to GC4) at different % of the fresh feed in the size range −6″ +1″ (−152 +25 mm). It is important to notice that the behaviour shown in Fig. 4 is affected by the dependence of the power consumption on the mill sizes.

Roll presses are also used in, particularly in upgrading existing ball mill circuits as pre-grinders to increase production or to reduce specific power consumption in grinding operation. Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can ...

(1985). Grinding Mill Power Consumption. Mineral Processing and Extractive Metallurgy Review: Vol. 1, No. 3-4, pp. .

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 8.3 Ad this can be used to establish the essential ...

To calculate theoretical horsepower required by a grinding mill to reduce feed material to a certain size from Bond grindability test data, it is necessary to apply the "Bond Third Theory of Comminution." The first step in this procedure is to calculate from the following formula the work index, which is the kw …
