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.

Our operational processes begin at our clinker facility, Aganang in Lichtenburg. Approximately half of the clinker produced is transported to the Delmas milling plant, making the process costeffective because clinker, rather than cement, is transported. This approach also enables beneficial raw material return loads to Lichtenburg.
