Air classification - ScienceDirect

Sieving is a supplementary separation process from air classification. For example, coarse fly ash obtained from an air classifier, as shown in Fig. 10.8, can be further separated by the sieving equipment offered by SWECO to obtain three fractions using 140, 70, and 40 mesh screens.

through size classification in a high speed air classifier has been made. It has been shown that for the fly ash of nearly same size (~ 5 µm), mechanical activation results in higher reactivity or geopoymerisation rate as compared to the air classified samples. Reactvity can also be altered by mixing raw fly ash with processed fly ash.

Fly Ash Properties - Weebly

The specific gravity of fly ash usually ranges from 2.1 to 3.0, while its specific surface area (measured by the Blaine air permeability method)may range from 170 to 1000 m2/kg. The color of fly ash can vary from tan to gray to black, depending on the amount of unburned carbon in the ash. The lighter the color, the lower the carbon content.

CHARACTERIZATION AND UTILIZATION OF FLY ASH

A comparison of fly ash particles sizes to those of several types of soils is presented in the Figure 1.1. Fly ash is a fine residue composed of unburned particles that solidify while suspended in exhaust gases. Fly ash is carried off in stack gases from a boiler unit, and is collected by mechanical methods or electrostatic precipitators.
