· Similarly, Chen et al. reported that fly ash particles could be activated through this ball milling, leading to a significant decrease in particle size, a rise in its BET surface. Although it could make the particle size continue to decrease with the increase of the ball milling time, when it reached 120 min, the particle size of mixture sample increased again, as shown in Fig. 3 f.
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
fly ash in concrete and provides guidance for the use of fly ash without compromising the construction process or the quality of the finished product. For the purposes of this document the replacement levels shown in Table 1 will be used to represent low, moderate, high and very high levels of fly ash.

size reduction is necessary and is accomplished by means of ball, rod, or pebble mills, which are often combined with air separators. Screening typically is carried out by means of two or more multideck sloping screens that are mechanically or electromagnetically vibrated. Pug mills are used for blunging, and rotary, fluid bed, and vibrating grate dryers are used for drying clay .
· Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand clay fulfill the need of silicon, iron and aluminum.
