The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement.

Ball milling (BM) is a well-established technique for producing different materials in powder shape. Dynamical analysis of BM helps to optimize the process through simple but general relations (e.g., definition of an equivalent milling time). Concerning the field of study of magnetocaloric effect (MCE), BM is used in different ways: as a single step process (mechanical alloying), as an initial ...

Ball milling was used to improve the dispersion of GO in a cement matrix in a planetary ball mill. Results indicated that the process had a negligible effect on the morphology of the GO but led to a 6.8% increase of the number of defects it contained. By adding 0.03 wt.% GO to the cement paste, its compressive strength increased by 9%, and the ...
