The unit power consumption shown in Table 2 is to grind the material to pass 3175 microns (trommel opening that was used). Typically, a commercial scale plant would grind this material to pass 6350 microns. The average specific power consumption (power at mill pinion shaft) for the AG tests was 10.73 kWh/mt, compared with 12.46 kWh/mt for the SAG tests.
At present, the average level of unit energy consumption of Cement Manufacturing Plants is at 33 kWh, in some Cement Manufacturing Plants, it could be 40 kWh higher than the average number. Through technology improvement, equipment update, and new type abrasion materials, the Cement Manufacturing Plant could reduce the unit energy consumption of the grinding process to 20 kWh.

In all equations D refers to the inside diameter of the mill in feet and v to the peripheral speed of the mill in feet per minute inside the liners. It is the general belief that the capacity, T, of a tumbling mill is ...
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 ...
This roller press can improve the grinding capacity by 50- compared to ball mill systems and reduce the power consumption of the grinding system by 30-40%, and 20-30% that of finished cement. The squeezed materials is easy to grind and 0.08mm fine material accounts for 30-30% and material smaller than 20 mm accounts for 65-85%.
E is the specific energy consumption, kWh/tonne, F 80 is the feed size to the primary BM T 80 is the transfer size (prim mill product size), P 80 is the final product (cyclone overflow). The following efficiency factors may also apply, but they must be greater than 1.0 otherwise use 1.0 EF2 is the open-circuit correction factor, EF4 is the ...

Feb 16, 2015 The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement.
Scale Up in Sizing for Grinding Mills. Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to
