Ultrafine grinding of fly ash with grinding aids: Impact

2015-3-1  Ultrafine grinding of fly ash The grinding experiment of fly ash was carried out by using laboratory ball mill. The type of the ball mill is Ф500 mm × 500 mm, 48 r/min and closed circuit, and the grinding media is composed by 60 kg steel balls (Φ40 mm, Φ50 mm, Φ60 mm and Φ70 mm) and 40 kg small steel forgings (Φ25 mm * 35 mm).

Ultrafine grinding of fly ash with grinding aids: Impact

Grinding aid (GA) improves the particle characteristics of ultrafine fly ash (UFFA). • Pozzolanic reaction degree and activity index of UFFA are also improved by GA. • Properties of blended cement containing UFFA with GA are better than without GA. • UFFA with GA improves the hydration process and microstructure of blended cement.
