Garnet abrasive is a kind of non-metallic abrasive that is used in the field of sandblasting and cleaning through deep processing of natural ore, and is being more and more widely used in sandblasting and cleaning because of its good performance.
Chemically stable, does not contain toxic substances, free silicon content does not exceed 0.1%, does not pollute the environment and does not cause health hazards, and is an excellent substitute for quartz sand and other consumable abrasives.
It has a high density, low crushing rate, and can be reused 3-5 times, and has a certain angle.
