粉煤灰的颗粒组成与磨细灰的火山灰活性

A Research on Particle Constitution of Fly Ash and Pozzolanic Activity of Fly Ash Ground Traditionally

将通过筛分得到的不同粒径范围的分选灰分别用普通球磨机磨细 ,探讨普通磨细方式对不同颗粒组成的粉煤灰的影响规律及其提高粉煤灰品质的机理。结果表明 :普通粉磨主要是对粉煤灰的粗大颗粒有重要作用 ,而对粉煤灰中的细颗粒作用不明显。

The particles of fly ash are separated by sieve method.The fly ash of different size distribution is ground by traditional mill.The effect rule of traditional grinding method on different particles of fly ash and the mechanism of improvement on quality of fly ash are discussed.The results show that traditional grinding affects on crassitude particles actively but not fine particles.
