Determination of particle size composition<br />
of the ash and slag<br />
Sieve analysis standard methods, on a<br />
series of Tyler sieves type, 200 mm diameter<br />
sieve surface, have determined the particle<br />
size composition, wet sieving.<br />
Table 5 and Figure 1 show the middle<br />
particle size composition of ash and slag<br />
samples.<br />
