Ball Mills' fundamental design enables a wide range of applications in industries like mining, where they are used for ore grinding, to construction, where they play a vital role in producing fine cement. In the chemical industry, these mills are indispensable for refining raw materials into a uniform, fine form. Each sector benefits from the ...
12. Working In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell.

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.
