Well, much of the world's sand is made out of the same stuff, tiny crystals of the mineral quartz, which is made out of silica and oxygen, the two most common elements in Earth's crust. And as you'll know if you've ever been through the crust of a sandwich that had sand in it, quartz grains are small and really tough. Here's why.
Silica is the most ubiquitous mineral in the earth's crust, existing in a wide variety of crystalline and noncrystalline forms due to the flexibility of the linkage among SiO 4 tetrahedra. The thermodynamically stable, room temperature form of silica is quartz, which is itself a widely available mineral and ingredient in many commercial ceramics and …

Hardness – Quartz is very hard (7 on Mohs scale), so grinding takes time compared to softer minerals like limestone. Feed rate – Pushing more quartz through the mill quickly results in a coarser grind. Go slower for finer particles. Machine speed – Faster milling speeds usually make smaller quartz particles but also more dust.
