mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton. On an overall basis, VRM consumes about 20 % lower specific energy than conventional closed circuit ball mills and is being widely used for raw material and coal grinding in the cement industry.

The majority of cement plants contacted in neighboring states are also adding limestone. Hence, adding limestone to cement is an industry standard practice in California and very likely an industry standard in neighboring states. Thus, the proposed project is the same as the industry standard.

Mill designs. 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.

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

The wet process kilns operating in Europe are generally expected to be converted to dry process kiln systems when renewed, as are semi-dry and semi-wet processes kiln systems. The clinker burning is the most important part of the process in terms of the key environmental issues for the manufacture of cement; energy use and emissions to air.
