The rotary kiln line, raw mill and coal mill were being operated by a PLC based central automation system in the plant. In general, it is quite difficult to ensure process control with such a conventional automation system, looking at long term stability and consistency, due to shifttoshift variations.
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.
These additives, along with the limestone, are fed from bins to the raw mill. An extremely important step in the cement process is to proportionally feed these materials to the raw mill to ensure the correct "blend" of these materials. One can think of this process as a "recipe" for making various types of cement.
