Abstract. A research team from the University of Utah is working to make inroads into saving energy in these SAG mills. In 2003, Industries of the Future Program of the Department of Energy tasked the University of Utah team to build a partnership between the University and the mining industry for the specific purpose of reducing energy consumption in SAG mills.
In other words, with the same grinding effect, the total weight of the balls can be reduced (from tons to tons) by reducing the diameter (from 50 mm to 40 mm) of the steel balls, which was the theoretical basis of the secondary ball mill energysaving project of Zhangzhuang iron.
Compared with the original twostage ball milling process, the cost of grinding power consumption is significantly reduced by about %, which provides a reference for the subsequent research on energy saving and consumption reduction in ball milling operations.
Dry and wet grinding experiments have been carried out with a Bond mill and a laboratory stirred ball mill. During the grinding processes, the grinding time and the filling ratio have been adjusted.
For instance, solutions to reduce energy problems during raw material crushing are described in [4,10]. Ref. [9] shows solutions for the slurry production process, Ref. [11] for prehomogenization, and Ref. [12] for drying. Technological opportunities are also shown for grinding [13], homogenization [14], granulation [9], preheating [15], heat
For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.
High Pressure Grinding Rolls (HPGR) circuits have the potential to reduce the Mining Industry's CO2emissions by up to megatonnes/year, or % when compared to the established Autogenous (AG)/SemiAutogenous (SAG)/Ball mill circuit alternatives. However, uptake of HPGR technology has been relatively slow.
Ball mills use steel balls and pebble mills use ceramic or natural rock for grinding. Operating in open or closed circuits, ball and pebble mills are designed for long life and minimum maintenance.

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is % of the total energy supplied to the mill setup.

An evaluation of Relo grinding media (RGM, Reuleaux tetrahedronshaped bodies) performance versus standard grinding media (balls) was made through a series of grinding tests, including a slight modification of the standard Bond test procedure. Standard Bond tests showed a reduction in the Bond ball mill work index (wi) of the mineral sample used in this study when using Relo grinding media.
