The cement used in this study has the specic surface area of 0.45 m 2 /g. The surface area of SF is about 20 m 2 /g. Therefore, the total surface area of the blend of cement and SF depends on the SF replacement percentage. For example, when cement is replaced by 20% SF, the total surface area of 1 g of this blend is 4.36 m 2.

In mineral processing, horizontal grinding mills must endure vibration, shock loads, moderate to slow speeds and a high concentration of particulates. In these conditions, contamination, loss of lubricant and even improper mounting techniques can all lead to failures for pinions or trunnions. And, of course, cause costly downtime and repairs ...

Grinding is the next step in the cement manufacturing process, and it can occur in either wet or dry forms. Wet grinding involves combining all of the materials in a mill with water and grinding it into slurry. In contrast, dry grinding processes combine and grind the materials without water, creating a substance known as kiln feed.
