Advances in cement grinding technology is slow and these advances are limited to more developed countries. Approximately 95% of the feed to the cement grinding circuit are clinker and the rest of the feed are "additives" which includes grinding aids. The quality of cement is measured by the surface area or the Blane index.

Multi-Disc Grinders. Multi-disc grinders use a rotating head with multiple abrasive diamond tools to grind the surface of the concrete. These machines are ideal for removing heavy coatings, smoothing rough surfaces and flattening a floor. Multi-disc grinders are also perfect for working in tight spaces, such as corners and edges.
