The relevance of ultrafine fly ash properties and ...

2018-10-20  The characterizations revealed the ultrafine grinding of fly ash resulted in not only the increase of their specific surface areas, also the decrease of crystallinity degree and the anion polymerization degree of silicates and aluminates. In comparison to CFBFA, PCFA showed a higher anion polymerization degree of silicates and aluminates.

Minerals Engineering Conferences - Ultrafine Grinding 06

2021-3-12  While conventional milling techniques may produce an ultrafine grind, the required energy rises sharply as the product size, often characterized in terms of the 80 % passing size, d 80, decreases. Ultrafine grinding techniques are those techniques which are more energy-efficient than conventional milling techniques in the sub 100 µm range.
