The other main admixtures present, beside quartz, are iron oxyhydroxides (mostly goethite) and anatase. Particle size of the silica sand deposits ranges from very fine to coarse but the most common are fine to medium grain size. The shape of the grains is sub-angular to sub-rounded and the Fe2O3 ranges between (0.01 – 1.5) %.

Silica sand is a refractory particle with a particle size of 0.020mm-3.350mm, its main mineral is quartz. It is a hard, wear-resistant, and silicate mineral with stable chemical properties. It is in milky white or non-volatile.

try. Sand and gravel are produced almost exclusively for road build-ing and concrete construction, depending on particle size and shape, surface texture, and porosity (IARC 1987). Silica sand deposits, commonly quartz or derived from quartz, typically have a silica content of 95%; however, impurities may be present at up to 25%.

The Silica sand mining process has a high degree of automation, low operating cost, high crushing rate, energy saving, large output, low pollution and easy maintenance. The machine-made sand produced meets the national construction sand standard, with uniform particle size, good grain shape and reasonable gradation.

The factory producing dry silica sand uses rotary desiccant containing gas fuel for drying. In addition, when the product needs to be pulverized to a particle size of -100 microns, it is dry pulverized using flint, gravel or porcelain grinding balls in a mill with silica sand or porcelain lining as the crushing medium.

Test materials and particle characterization Silica sand with different particle size distributions, known by their commercial names as Sand 2 and Sand 55, were used. A portion of Sand 2 was milled to produce a third sample with a finer distribution. The particle size distribution curves of these sands are shown in Figure 2. Three distinct
