Ceramic Foundry Sand with the high quality bauxite as the raw material, blowing into the ball after remelting smelting, is a new type of steel casting foundry sand.It is characteristic as high temperature resistant,small amount of thermal expansion, easy collapse, good renewable performance,good casting properties, received the recognition from the cast made experts domestic and overseas. Widely used in all kinds of casting method,sand casting, special casting( casting, solid type, evaporative pattern casting, ladle flow guiding sand and so on ).Also used for shot peening, low expansion of high-temperature coated sand producing. 200mesh-270mesh used for evanescent mode coating producing. Adding 10-35% can effectively increase the air permeability, and suitable for using all kinds of casting binder.It has been used by numerous domestic and international cast iron and nonferrous metal casting production factories. Ceramic Foundry Sand Technical Specification: 1.Chemical composition: AL2O3 75% Fe2O3 3%

Silica (SiO2) is the name given to a group of minerals composed solely of silicon and oxygen. Silica sand deposits are most commonly surface-mined in open pit operations. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application. We are a leading supplier of silica sand in its raw form and as a semi-finished and silica sand based finished product. We are able to process and supply silica sand of various specifications to meet the demand of the individual job and varied industries. Applications : Manufacturing of Glass, Ceramics, Abrasives, Silicon Carbide, Paints Sodium Silicate, Ferro Silicon, Refractory, Filter Media, Sandpapers, Whetstones, Scouring Powders and in Sandblasting, construction chemicals, etc.

Dewatering screen is widely applied for dewatering, desliming, deintercalation, which can be used to sand and stone washing plant, coal preparation plant, sludge recycling, mineral processing plant, tailings dry discharge and more. So it is also called sand and stone dewatering screen, mine dewatering screen, coal slime dewatering screen, tailings dewatering screen, high frequency dewatering screen. Base on lower water content sand is well needed and sold in market, we do research and manufacture a series new type dewatering screen. TS dewatering screen is mainly used in mining, construction for coarse or fine sand dehydrate processing.With the advantages of simple structure and easy maintenance, it becomes a hot seller in our market.

Fused quartz from 200nm to 2.2um has high transmittance and low thermal expansion coefficient, which makes it an ideal choice for spherical lens in ultraviolet ray, visible light and near infrared spectrum applications with strict requirements. Spherical lens is commonly used to improve signal coupling between optical fibers, transmitters and detectors, as well as objective lenses in endoscopy and bar code scanning applications. Hemispherical lens simplify the integration of the whole system.
We are leading suppliers of silica sand for various industrial use. We are supplying bulk quantity of silica sand for construction and foundry industrial with Sio2 around 99% and low fe contents ranging from 0.2-0.4%. Our silica sand is also used by glass industries. please contact us for regular supplies of silica sand for various industrial use.
