Calculation of the power draw of dry multi-compartment ball mills

May 6, 2004 . In this paper, a new approach for the calculation of the power draw of cement grinding ball mills is proposed. For this purpose, cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills, ranging in diameters from 3.2 to 4.8 m. The ball loads.

The effect of ball size on mill performance - ScienceDirect

If it is also assumed that the mean overall values of Si for a mixture of balls is the weighted mean of Si values for each ball size, equations are derived for calculating this mean value. As an example, the results are used in a mill simulation to show the quantitative effect of different ball mixes in a two-compartment cement mill.

High-Efficiency Separators - IEEE Xplore

Abstract-High-efficiency classifiers improve the grain size distribu- tion of the finished cement and reduce grinding power requirements. Theoretical calculations indicate potential power savings of up to one-third at the main mill motor when applying high-efficiency classifiers instead of conventional separators at a cement.

How to calculate cement ball mill capacity - Quora

It's difficulty to calculate capacity of a machine or maximum capacity. It's depend on a lot of parameters. But you can calculate specific energy(unit kW/kg e.g. 0.05kW/Kg) to know which mill better. The low specific energy will means more capacity for a mill with stock motor power. And you can adjust your.
