4. Grinding. Clinkers are ground in ball mills and tube mills after controlled cooling. The cooling rate of clinkers affects the strengthgaining properties of cement. About 35 % gypsum is added during grinding to the cooled clinkers to prevent flash set. Closedcircuit grinding is done in tube mills.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
