It has. selfcementing pozzolanic properties. When Class C fly ash contacts with water, it will. harden gain strength over time. Generally, it contains more than 20 lime (CaO). Alike, Class F fly ash, the selfcementing Class. C does not require any activator. The higher. contents in Class C fly ash are alkali and.
Blended Cement an overview | ScienceDirect Topics
The principal difference is the point of feeding fly ash in VRM systems. VRMs have builtin highefficiency separators. Fly ash, being a naturally fine product, can bypass the mill and be fed to the separator at the mill. The roller press and ball mill combination is also being adopted in a variety of ways to make cement.

12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.

A pilotscale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of % was observed for the dry VRM compared to the wet ball mill (% for the circuit).
