Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

When material particle gravity is greater than centrifugal force, they will be crushed due to the impact force. At the same time, during the operation of the mill, the sliding movement of the grinding media to each other also produces a grinding effect on the raw materials. The rest material is discharged through a discharge hollow shaft.

With close spacing and small grains, the surface roughness produced is low but the grinding forces are increased. With wide spacing and large grains, the reverse is true: roughness is greater but forces are lower. However, it is not only grain spacing that affects grinding behaviour but also grain sharpness.
