Dec 01, 2009· Table 2 shows a comparison of two sands that have the same AFSGFN but different distributions. Sand A is a 5sieve sand because 10% or more of the sample was retained on each of five adjacent sieves (40, 50, 70, 100 and 140). Sand B is a 3sieve sand because 10% or more was retained on each of only three adjacent sieves (50, 70 and 100).
Jun 04, 2019· The flow spiral length of EMCs with different fillers in descending order is fused silica > foundry sand > crystalline silica > glass beads. (4) The tensile strength of EMCs final products with glass beads, foundry sand, and crystalline silica is nearly the same and it is independent of SiO 2 weight content in the filler.
