The ball mill has two rotating chambers with ceramic balls that grind the clinkers. The clinkers are fed from one side. The mill is heated at various temperatures along the separator. The temperature evaporates the water in the clinker and initiates various chemical reactions within the chambers. The size of the ball, speed of rotation and duration of grinding will impact how fine the cement is.

For cement grinding, the technology development away from ball mills has taken a different route. The development of roller presses in the 1980s took advantage of the benefits of higher-pressure grinding and many presses were retrofitted to ball mills as pregrinders. The main benefit was seen at lower Blaines as the first generation of presses suffered from stability problems when attempts ...
