ball milling - metallurgist & mineral processing engineer,the average ball consumption for mills in closed circuit has been plotted in fig. 15 for steel balls and for cast composition balls. enough data are not available to plot curves for hard and soft ores, and individual figures will vary considerably from the average of the curves, which are given merely a guide as to what may be expected and also to show the increased consumption with finer grinding..china 911 metallurgist ball mill manufacturers and factory,product description: ball mill is a essential equipment for further grinding the material after it is crushed. it continues to grind minerals by grinding media to reach a certain fineness to achieve a better grinding effect. most of mines use overflow ball mill..

ball mills archives mineral processing metallurgy. ball mills grinding mill surging the phenomenon of “surging” in a mill is a subject upon which very little has been written; presumably because it is a condition which cannot be tolerated in mill operation and which must be eliminated by variation of some or many of the physical dimensions or characteristics of the mill or mill charge.
the objective of the study conducted by the authors is to determine what media size(s) addition will maximize any given plant ball mill’s grinding efficiency. the functional performance parameters “mill grinding rate through the size of interest,” and “cumulative mill grinding rates” from both plant and small-scale tests are applied to this task.
