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).

1. Introduction. Fly ash (FA) is a silicoaluminate rich pozzolanic powdery material formed during the combustion of the pulverized coal. FA was used primarily as a supplementary material for the replacement of ordinary Portland cement to produce concretes with the low carbon dioxide footprint (Mehta, 2004).FA was also converted into geopolymer precursor as an additive binder for the ...

In West Bengal, presently 65 nos. fly ash based brick units are running. There are more 16 units upcoming in 2013. With a single machine 20,000 nos bricks making are possible in two shifts/ day. The price of the cement based fly ash bricks is little bit higher than the lime gypsum based bricks, but lower than traditional clay burnt brick.

the fly ash as the sole cementing material (Cross 2005). In addition to providing an indication of the mineralogy and reactivity of the fly ash, the calcium content is also useful in predicting how effective the fly ash will be in terms of reducing the heat of hydration (Thomas 1995), controlling expansion due to alkalisilica reaction (Shehata

Highenergy mill (HEM) has a wide application in material preparation, activation and synthesis. In the present study, fly ash was selected to be milled by HEM under the speed of 700 rpm and the balltopowder ratio of 10:1 by weight, but varied periods of milling time. The changes in physical and morphology properties of the milled fly ash were determined using BET analysis and scanning ...
