By Patrick Murray August 25, 2011. Cement producers have faced a significant rise in energy costs with the introduction of dry-process kilns, with a record average consumption of 100-200 kWh per ton of cement, according to the 2009 Cement Plant Operations Handbook. This complex challenge, coupled with rising fuel and energy …
A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at 2800 blaine I chamber liners
Estimation of the Specific Energy Requirement for Size. Table 1 shows a comparison of the specific energy values calculated from Eqs. and for the 100 mesh test sieve (S = 150 µm) and seven values of G in the range of 0.33–3 g/rev.It can be seen that at a G value of 1.5 both the equations give the same estimate of the specific energy.

As well the consideration of production costs and carbon footprints, one key issue is energy consumption. For reference, the grinding process represents a significant part of a cement plant's electrical demand, in the range of 50 – 70% of the total integrated plant's needs. Therefore, limiting grinding power demand is a major industry focus.
Total power consumption for grinding circuit as a whole is also less by about 30% compared to closed circuit ball mill in spite of higher fan power. Feed size can be as large as 75 to 100 mm. Feed size can be as large as 5% of roller diameter. Roller Press. Roller press consists of two rollers lined with wear resistant material.
