Pure quartz sand, fine quartz sand

According to the quality of quartz sand can have an ordinary quartz sand, quartz sand and two refined.

The main specifications of quartz sand :4-6 ,6-10 mesh ,10-20 mesh ,20-40 mesh, 40 mesh-70 mesh ,70-100 mesh, 200 mesh, 270 mesh, 325 mesh.

Quartz sand is mainly used for the manufacture of glass, refractories, smelting ferrosilicon, metallurgical fluxes, ceramics, abrasive materials, casting, the use of quartz in the construction of a strong acid etching medium capacity, used for extracting acid and acid of concrete mortar. Quartz hardness of 7, the proportion of 2.65, the color is milky white, yellow, brown and gray, quartz has a higher fire resistance, melting point of 1730 degrees Celsius.
