Dec 1, 2017 In the first part of this series, we explored what defines a cognitive manufacturing plant. In the final step, the cement mill grinds the clinkers using horizontal ball mills. McKinsey and Company estimates net saving of $1M per year for large processes and $50-100K per year for midsize processes.

Cement, mining, processing,Information. Cement manufacture, like many other manufacturing processes, begins at the mine, where the raw materials like limestone, silica, aluminates, feric minerals and others are obtained. Sometimes, the raw materials are wet ground in the ball mill by adding water, and form a slurry.
