The main raw material of siliceous ramming material is silica, which is the general name of ganglite, quartzite and quartz sandstone.Acid refractory brick mainly used in metallurgical industry.Pure silica can be used as quartz glass or refined as monocrystalline silicon.In the chemical industry, it is used for the preparation of silicon compounds and silicates, and also as the filling material of sulfuric acid tower.Building materials industry for glass, ceramics, Portland cement and so on.
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.

Introduction Fumed silica is hydrophilic fumed silica(silicon dioxide). It is high purity and fluffy powder with typical specific surface area of 150g, 200g, 300g, 380g. Furthermore, it is characterized by an x-ray amorphous structure. Positive effects: Optimum adjustment of rheology during processing Reinforcement of silicone elastomers Thickening of non-polar liquids Free-flow of foodstuffs and industrial powders High chemical purity Excellent insulation properties, even at high temperatures Conversion of liquids to powders, e.G. Pharmaceuticals, cosmetics Gelification of battery acids Rheology control of greases and lubricants Detailed application area: Coating:ep-, up-, pu-, acrylic resinpmma/mmapvc plastisol Sealants:pib, pu, acrylic resin, butyl rubber, rtv silicone sealant Film:hydrate celluloseperpipvcpapepp pvcf Gel coat:laminated resinupmfpf resin Casting film:puepacrylic resin, rtv silicone rubber Cable:htv silicone rubber pe Foam plastic and polymer:epspvcppsappa ep Adhesives:epuppp pupvac Silicon rubber:rtv-1crtv-2c lsr(vms) Fluororubber Natural rubber
Due to the unique features of small particle size, large specific surface area and highly active surface, fumed silica is widely applied in silicon rubber, paint, adhesive, printing ink, plastic, comestic, agriculture and pharmacy. It's functions include reinforcement, thickening, thixotropy, extinction, sterilization, anti-uv light and etc. 10kg/bag, 20bags/pallet
