Product introduction:

  Silica sand, sreened and refined from the excellent quality quartz sand, can be used as the hydraulic fracturing proppant under the closure pressure of below 35MPa. Various kinds of high-quality silica sand with different specifications can be made, thanks to our state-of-the-art production technology in this field. 

    Refinery process:

 Roundess of silica sand has been greatly improved through a series of shaping processes. (The comparison picture is as follows:)

Roundness can be improved by 16.7% and sphericity by 14.3%. After being shaped, the foreign matters like feldspar, mica and CaCO3 are substantially reduced. 

     Features:

  Good roundness and sphericity,  with better crushing resistance and flow conductivity

    Particle Size Avaiable: 

  850-425um (20/40 mesh), 600-300um (30/50 mesh),  425-212um (40/70 mesh),  212-150um (70/100 mesh),   212-106um (70/140 mesh),  212-75um (70/200 mesh)
