cement clinkering grinding

Clinker (cement) - Wikipedia

Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.

The cement mill

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

Who Invented Cement?| Concrete Construction Magazine

Jun 11, 2019· Apparently, he discarded some of the product—the overbaked "clinkers"—because it was too hard to grind. It was William, the son, who seems to have had the bright idea of saving and grinding up the clinkers. And it was the clinkers that yielded the cement that actually rivaled Portland stone for hardness and durability.
