Sintered bauxite as blasting abrasive grain
Sintered Bauxite
Sintered bauxite is made by sintering fine bauxite ore. Bauxite is the main ore used to produce Aluminium and consists 75% of Aluminium Oxide. It is a hard and unyielding abrasive in spherical shapes.
Applications
Bauxite beads are Often used to replace brown fused aluminium oxide, Bauxite beads can be used with conventional abrasive blasting equipment, air-compressed pressure and suction jet blasting equipment. Sintered bauxite is also used for the following applications: antiskid flooring, carving etching, finishing, grinding, lapping, polishing, rock tumbling, lapidary, sandblasting, slurry mixes, surface preparation and tumbling. It is exceptionally well suited for use with air-compressed jet blasting equipment, both pressure and suction.
