### Experimental characterization of chalcopyrite ball mill

A detailed characterization of chalcopyrite ball mill grinding processes, in both batch and continuous flow processing modes, has been carried out in this work. The referred characterization involved different mineralogical, rheological and energy consumption-related aspects.Herbst et al. (1982) proved the scale-up from 10 × 11.5-in. ball mill to 30 × 18-in. continuous flow mill. In a similar study, Herbst et al. demonstrated successful scale-up from the 10 × 11.5-in. ball mill to 14 × 22-ft. plant-scale mill. Because of number of such studies, this scale-up procedure is imbedded in Moly-Cop Tool’s “BallThe Evolution of Grinding Mill Power Models SpringerLink

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.The influence of the ball charge grading on the specific energy demand, characterised by the average ball diameter, was tested by means of a discontinuous laboratory ball mill. The results showed that by using a finer ball grading the specific energy demand could be lowered considerably.Optimization of continuous ball mills used for finish-grinding

In this paper, different from the traditional two-input-two-output model of the ball mill grinding process, a three-input-three-output system considering the influence of three factors (i.e., fresh ore feed, dilution water, and mill feed water) is put forward to improve the accuracy of modeling.Optimization results confirmed that the balls to powder weight ratio were the most influential process parameter. The optimum process parameters setting concluded that balls to powder weight ratio are 20:1, the optimum ball mill working capacity is 2 L while the optimum speed of the ball mill is 105 rpm.Comparative Study on Improving the Ball Mill Process

1. Introduction Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).The absolute fineness of the ball diameter and the ball charge grading are important factors for the optimal operation of a ball mill. Therefore, the effects on breakage kinetics of the ball diameter and the fractional ball filling were investigated on the barite powder at batch grinding conditions based on a kinetic model.Optimization of continuous ball mills used for finish-grinding
