To calculate theoretical horsepower required by a grinding mill to reduce feed material to a certain size from Bond grindability test data, it is necessary to apply the "Bond Third Theory of Comminution." The first step in this procedure is to calculate from the following formula the work index, which is the kw-hr required to grind one short ton of material from a theoretically infinite ...

Power Consumption in Cement Manufacturing Plant: The cement industry, as a traditional high power consumption industry, power consumption in the cement grinding process takes a large ratio in the whole production, electric power consumption is about 60%-70% of the total consumption.

The results showed that power draw of the cement mills could accurately be predicted by the method proposed in this study. Key words: power draw, cement, dry grinding, ball mill INTRODUCTION Energy is the most important cost item in a cement plant. About 60% of the electricity consumption for cement production is used for grinding the raw material

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a 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 ...

Figure 4.3 Specific power consumption section wise break-up From the above pie chart, it is evident that the cement mill section (37%) is the major contributor to overall SEC, followed by kiln section (26%) and then by Raw mill section (22%), while all the other sections of the plant

Improvements in New. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if this is not required by the market! 20 25 30 35 40 45 50 55 60 2500 3000 3500 4000 4500 5000 Open circuit kWh/t Closed circuit kWh/t.

of cement will be the world's largest cement mill. The mill will be grinding various blended cement qualities with clinker portions of up to 90 % and slag portions of up to 65 % to product fineness degrees of 4000–4800 cm 2 /g acc. to Blaine. A MultiDrive ® with 6 single drives, each of . 1920 kW, will be used to drive this mill.
