Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.

Sand Blasting Grades: The most common grades used for Sand Blasting are the medium coarse grades, â?¢ Mesh 30-60 â?¢ Mesh 20-40. Sandblasting is a mechanical process with which the shallower part of a material is eroded through abrasion due to a pressurized abrasive jet. The most frequent application is metals surface cleaning, yet other possible uses include engraving of images on marble, stones and tiles.
Fused cast magmalox block, also named fused cast wear-resistance block, fused cast skid rail block, and fused cast zirconia mullite block.
