on energy consumption of the laboratory ball mill refiner for chocolate. MATERIAL AND METHOD The Box-Behnken experimental designwith three central points (nc=3) (Myers et al., 2009) was used to evaluatethe influence of milling variables (3 input factors) and their interactions on power requirements and energy consumption of the stirred ball mill.
Ball milling has several advantages over other systems: installation cost, power requirements and grinding medium usage are low; it can be used for both batch and continuous operation; it is suitable for open- and closed-circuit grinding; and it is applicable for materials of all degrees of hardness. Ball mills of almost 30-foot

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...
Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - .
However, in pure energy efficiency terms, the benefit of grinding power reduction is countered by the very high power required by mill fans. In addition, the absence of the heat generated in a ball mill and the high volume of air required by the vertical mill have required the provision of waste heat from cooler exhausts and/or auxiliary ...
Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.

The power drawn by the Vertimill motor is required to establish the grinding rate. Motor power should be measured using corrected power. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total media charge will diminish, and the power draw will decrease.

Oct 05, 2006 · For ball milling you need the Bond Ball Mill Work Index. Units are kWh/t. Knowing the Bond Work Index and the feed and product sizes you can calculate the power input required. If you post more detail about the application and ore, we might be able to predict performance using values from similar ore types. Cheers, Nigel
