3.for Sandblasting: It is mainly used for various material workpieces to decontaminate, derusting, prevent corrosion, remove oxide skin, light- decorate , process pattern effect and so on.
There are three factors the decide the effect of Brown Fused Alumina for sand blasting :
1.The grinding ability: the higher grinding ability ,the better for sand blasting.
2.The bulk density: the higher bulk density ,the better for sand blasting.
3.The dust: the lower dust, the better for sand blasting.
Brown Fused Alumina with high bulk density and air cleaned,the quality of this kind of Brown Fused Alumina is very excellent for sandblasting.

4.for Precision Casting: Brown fused alumina melt film precision casting sand is the latest corundum products self-developed by RuiShi Company to meet the market demands. Based on the production of the brown fused alumina and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers’ requirement. The precision casting sand of RuiShi Brand has high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.
