Milling is among the most energy-consuming technological stages of copper ore processing. It is performed in mills which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive systems.
Mar 23 2021 the parameters of the mill. In another approach the energy efﬁciency of milling may be improved by adjusting the parameters of the comminuted material with the use of chemical additives or water. Chemical additives may however have a negative environmental impact 22. Energy savings may also be found in the ball mill drive systems.
Jan 01 1989 EXPERIMENTAL WORK Experiments carried out on samples of copper ore andesite and limestone determined the value of Wi in a laboratory Bond ball mill with different aper- tures of test screen. Table I shows the values of Wi with the corresponding numerical values for Pk P F and G. Fig. 1 shows the relation Gf~-~k using the data from Table I.
