## Calculation of energy required for grinding in a ball

The Bond work index, W i, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.Therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work index W iball mill energy consumption,brief ments on ball mill energy consumption. grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded

## Comparison of energy efficiency between ball mills

The measured Bond ball mill energy consumption in relation to mill revolution from the data of various ore types and feed sizes (Shi et al., 2006). A similar approach was taken for the stirred mill tests, with the net energy consumption by the motor measured with a power meter. It was noticed that the stirred mill only took approximately 20 s to complete one cycle grinding in the locked-cyclehow to calculate power consumption in ball mill,TECHNICAL NOTES 8 GRINDING R P King Mineral Technologies,ball mill power calculation ,Figure 85 Effect of mill filling on power draft for ball mills The data,A simple equation for calculating net power draft is,Austin's formula gives slightly higher values than Morrell's for mills that have length equal Power Consumption

## Bond Work Index (Energy equation) Grinding

E is the specific energy consumption, kWh/tonne, F 80 is the feed size to the primary BM; T 80 is the transfer size (prim mill product size), P 80 is the final product (cyclone overflow). The following "efficiency factors" may also apply, but they must be greater than 1.0 otherwise use 1.0: EF2 is the open-circuit correction factor, EF4 is the oversize feed factor, EF5 is the fine product factor.MODELING THE SPECIFIC GRINDING ENERGY AND BALL-MILL ,MODELING THE SPECIFIC GRINDING ENERGY AND BALL-MILL SCALEUP K.
