Abstract:
PCT No. PCT/DK95/00371 Sec. 371 Date Apr. 18, 1997 Sec. 102(e) Date Apr. 18, 1997 PCT Filed Sep. 15, 1995 PCT Pub. No. WO96/08542 PCT Pub. Date Mar. 21, 1996A grinding aid for use in an abrasive material comprising abrasive grains and a grinding aid consists of particles obtainable by crushing a cold bath from the manufacture of metallic aluminium by reducing Al2O3. This grinding aid is produced by a method wherein the cold bath is crushed, optionally in several steps, whereby particles of an optional free metallic aluminium residue are rolled to flakes, following which the crushed material is screened to optionally sort out the formed aluminium flakes, and then the residual material is recovered as a product or is optionally subjected to further grinding and optionally screening to provide a material which preferably has a grain size distribution corresponding to 100% by weight less than 100 micrometers. This grinding aid lends itself for use in the product of abrasive materials.
