Brand Name: HAIXU ABRASIVES
Model Number: AFS25-AFS90
Place of Origin: China
Product Description:
Ceramic foundry is an advanced substitutes of quartz sand in casting field. Ceramic sand is made from calcined bauxite with main content of aluminum oxide processed by melting,blowing,sieving and blending. After melting calcined bauxite with 65-90% aluminum oxide in high temperature electric arc melting device, the outflow of ceramic blown into fine particles. Then after cooling and sieving,the ceramic sand become finished particles with different size grade.
Feature:
1.spherical,good mobility,good ventilation
2.smooth surface,compact structure
3.chemically neutral material
4. high temperature resistance
5.recycling and reusing,highly cost effective.
