Calcined Brown Fused Alumina 95% for Bonded and Coated Abrasives

Calcined Brown Fused Alumina 95% for Bonded and Coated Abrasives

1. Brown Fused Alumina Descriptions

Brown Fused Alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000oC. A slow solidification process follows the fusion, to yield blocky crystals. Strict control over Titania levels during the fusion process ensures optimum toughness of the grains.

The cooled crude is further crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use. Dedicated lines produce products for different applications.
