Garnet sand Garnet abrasive is naturally occurring non-metallic mineral, We provide Garnet, a class of silicate minerals that have been utilized as abrasives in a number of industrial and pre-industrial production processes. On the Mohs Scale, it has a hardness of 7, making it incredibly durable for industrial applications. It is a very hard mineral which is dense, hard and sharp in nature. Garnet is widely used in sand blasting machine due to its low free silica nature. Garnet minerals are free of heavy ingredients and toxic components. In addition, it has low friability which ensures its recycling up to 5-8 times. Garnet offers a relatively high density that ensures a fast detonation speed.
