Garnet sand is a natural product with chemically inert, non-toxic metals, Mohs hardness 7.5-8 , With its good hardness,garnet has been used as a gemstone and blasting abrasives. Garnet sand suits for water jet cutting machine, in order to have a good performance, the most important step is washing, the good washing can make the sand clean, we have 6 steps washing, so it is cleaner.
Raw Materials: Natural high quality garnet sand.
Processing: 4 times of crushing, 6 times of washing, 3 times of magnetic, 4 times of screening. It could keep sure high quality without soil, ash and other foreign substance.
Features of the garnet sand: Hardness, abrasion resistant.
