Product Description

Brown corundum Ba mark sand

Bamak brown corundum process: is manually selected brown corundum block, using roll, ball milling, Bamak and other equipment processing, granularity from F8-F325. Mainly used for polishing, grinding, industrial grinding, etc., can also be washed according to customer requirements, pickling treatment and other processing methods to meet the different needs of customers.

Barmak brown corundum specification: After pre-furnace and special process re-treatment, reduce the residual carbon content in brown corundum, so that the product in use is not pulverized, non-bursting, toughness is the abrasive abrasive industry, refractory industry preferred raw materials.

Uses: Mainly used in ceramic abrasives, high-grade abrasives, organic abrasives, abrasive belts, coated abrasives and so on.

The characteristics of Bamak brown corundum are as follows: calcined brown corundum C < 0.05%, low carbon brown corundum C < 0.10% and common brown corundum C < 0.15% according to the residual carbon content. Ordinary name is also known as emery, bauxite, carbon materials, iron scraps three raw materials in the electric furnace after the melting reduction of brown man-made corundum, it is brown corundum.
