Get PriceDrives also are used to power roller mills for grinding different blaine of slag for cement, and for starting and running multiple roller mills, ball mills, and overland conveyors. A China-based cement plant used VFDs to significantly reduce its energy consumption in its dry-process kilns, responsible for production of 1.4 million tons of cement each year.

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.
