Reducing energy consumption of a raw mill in cement

Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding process of raw materials .While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction .About 65% of the total electrical energy used in a cement

Modelling SAG milling power and specific energy

SAG mill power consumption (Pc) in kW, in 4 grinding circuits (GC1 to GC4) at different % of the fresh feed in the size range −6″ +1″ (−152 +25 mm). It is important to notice that the behaviour shown in Fig. 4 is affected by the dependence of the power consumption on the mill sizes. This fact will be addressed later on in this paper. 3.

The baseline idle power, which was the power consumed when the mill ran without the material in it, and rated power were 12 and 42 kW for the hammer grinding circuit, respectively. All runs that were completed below the full rated power were corrected in this manner to remove the power variations due to the feeding rate variations among runs.

IsaMill - Wikipedia

For example, grinding a pyrite concentrate so that 80% of the particles are less than 12 µm (0.012 mm) consumes over 120 kilowatt-hours per tonne (kWh/t) of ore in a ball mill using 9 mm balls, but only 40 kWh/t in an IsaMill using a 2 mm grinding medium. Figure 3.

Cement Vertical Mill - Vertical Grinding Mill - Vertical Mill

The cement vertical mill has low energy consumption. The power consumption of its grinding system is about 20%-30% lower than that of the ball mill, and this power saving effect is more obvious with the increase of raw material moisture. In addition, the vertical mill adopts a fully enclosed system, which works under negative pressure, without dust, and has a clean environment.
