Cement manufacturing involves a grinding process of clinker, gypsum and secondary mineral additions, usually carried out in ball or vertical roller mills. Efficiency of grinding (in terms of energy actually used to increase cement fineness over total energy) is usually very low and reported to be in the range 10-30%.
