While I continued with my online refresher on cement, I learned that there were three major developments in the manufacturing process that led to modern Portland cement [2]: the development of rotary kiln, addition of gypsum to control setting, and the use of ball mills to grind clinker and raw materials.
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill .
