Ball mill operating parameters by mill operating parameters. It is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters. mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected for the present study. It is hoped that the analysis of the with a view to developing a sound basis for the design and scale-up of ball mills, a large amount of data available in the literature were analyzed for variation of the two key mill performance parameters: power specific values of the absolute breakage rate of the coarsest size fraction, and absolute rate of production of fines, with some of the important operating and

How to realize automatic control of the feed rate in ball 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 shows that there is no linear relation between In ore concentration plant, single parameter and fixed value feeding control is a traditional method to control the feed rate of ball mill. this system is composed of recorder, scr governor, belt scales, funnel automatic switching device, and three DC motor driving belt feeders.
