cement production is as low as $6 per tonne in China as opposed to $30 per tonne in Nigeria; this has contributed largely to the high and persistent rise in unit cost of ce- ment production. There is thus the need for the adoption of energy efficiency in cement production in Nigeria. Recently, there has been an increasing interest in using

cement mill operations in four ways: • More consistent quality (grade). The continual monitoring of the mill loading and the adjustment of the feed and separator results in reduced variations in cement grade. This has the added benefit of a more consistent product quality. The control strategy is designed to respond to disturbances in the
