Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

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 superfine 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.
