The Material Yield Percentage in a cement manufacturing plant measures the efficiency of raw material utilization in the production process. It reflects the ratio of the amount of usable product produced from a given amount of raw materials input. In simpler terms, it indicates how much of the input materials are turned into final cement products.

Beside technological improvements, the composition of raw materials and the final product may also influence energy consumption. As shown in Fig. 1 after the crushing process, pre-blending and grinding, the raw materials are calcined to produce the semi-final product called clinker. The calcination process uses approximately 24% of the …

The majority are raw meal and cement mills, designed as either vertical or ball mills. Cement production runs continuously with very limited reserve capacities and little redundant plant or equipment. The greater part of the equipment therefore has to run around-the-clock or – if there are specific restrictions – throughout the day.

Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further
