the cost of energy rises [3−7]. Elec-tricity represents up to 30 % of the manufacturing cost in ceramic pro-cessing and most of the energy is consumed during the grinding oper-ation [8]. In order to overcome the limits inherent in a ball mill system, partic-ularly for fine grinding, the agitator ball mill has been developed, which
Cost optimization of stirred ball mill grinding ...
An example is the selection of rotor speed. In general, lower speeds result in lower energy consumption per ton of material ground but at the cost of reduced mill capacity per unit volume. Because stirred ball mills have a high capital cost per unit volume the trade off between energy consumption and capacity becomes critical.

Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.

Energy consumption in ball and rod mills reaches up to 10–20 kWh per ton of rock. According to the study prepared by the U.S. Department of Energy [ 3 ] the biggest potential for energy savings in all of the energy-intensive ore and coal mining-related operations is to be found in grinding optimization (see Figure 1).

Abstract - USGS
The CIL and autoclave-CIL models were developed from individual cost estimates prepared by Scott Stebbins. Mine-run ore is initially crushed with a jaw, then a cone crusher. Crushed ore is then ground is a semiautogeneous grinding (SAG) mill and sent through cyclones. The oversize is sent to a ball mill, while the undersize is sent to a ...

However, the cost of liners was significant, Stokes said, citing running costs of the mills at 1s 2d per ton of sand, with flints and liners accounting for half of this. The remainder was presumably accounted for by the energy input to turn the mill. Purely for interest, that milling cost converts to the equivalent of US$7.20 per ton in May ...
