Basisil-200 is a hydrophilic fumed silica with a specific surface area of 200m2/g, and it is synthetic, hydrophilic, amorphous silica. The original particle size can be 5- 40 nm. Itâ??s a kind of high purity white colloidal powder. Widely used in coatings, printing ink, resin, silicone sealant, adhesive etc.
The total gyratory movement of the square gyratory sifter can rapidly spread, stratify and separate the material. The unique gyratory motion can quickly spread the material across the full width of screen at the feed end, driving the particles move forward contact with the screen surface. The large horizontal amplitude can improve the sieving effect of the near-size particles, and can improve the material handling capacity of the machine.
Ashapura's rounded to sub-rounded shaped silica sand grains (Supsil and Castsil) are naturally suitable for glass and foundry applications. Our ability to process narrow size controlled silica sand grains to achieve required AFS-GFN numbers for foundries sets Ashapura apart.
Refinements are carried out through mineral processing techniques such as magnetic separation and spiral gravity concentration to achieve lowest ferric impurities to suit advanced glass applications such as thin LED touch screen glasses.
