Then, cooled clinker ground in a ball mill. For the prevention of flash-setting of the cement 3 to 5 % of gypsum is added. Ball mill is a hardened steel ball that has different chambers that charged in sequence forward. The particles are crushed into the required fineness level. And particles are separated by air currents and taken to storage.

Samples of original SSA were ground using a laboratory ball-mill (Gabrielli Mill-2). SSA samples were introduced into the bottle-mill containing 98 balls of alumina (2 cm diameter) and were ground during 2.5, 5 and 10 minutes. Mortar specimens cast in square prismatic mortar molds with internal dimensions of (40×40×160) mm were used.
