Garnet sand abrasive is suitable for water-jet cutting

Garnet is the natural mineral abrasive, it is the best for waterjet cutting in terms of cost, cutting speed and health hazards. Garnet 60 mesh, 80 mesh, 20/40 mesh, 30/60 mesh usually be used for waterjet cutting.

The garnet is basically an accumulation of loose mineral grains, which have a very similar chemical composition. Although the abrasive garnet is a silicate, but still natural sand whose main ingredient is the heavy mineral garnet sand. With the help of crushers, garnet sand is broken out of rock – the so-called “crushed sand”. For waterjet cutting, this abrasive is indispensable when cutting hard materials.

Garnet sand properties:

There are transparent and completely opaque grenades, some are glassy, ​​others are shiny. Their extraordinary hardness makes many grenades the preferred abrasives for glass, wood or plastic. Pyrope, Spessartine, and almandine come to a Mohs hardness between seven and eight. Another feature of garnet has opened up the field of waterjet cutting garnet sand – its remarkable splinter resistance (toughness) makes garnet sand an ideal cutting material or metal-free multiple shots means that can be used in high-pressure waterjet cutting.

• Garnet has a hardness of 7.5 – 8 Mohs
• The specific gravity of garnet: 4.1 g / cm³

Requirements placed on the cutting means by the water-jet cutting technique Garnets made of garnet sand must meet certain criteria for their suitability. Thus, in the interests of OSH, it must be ensured that no chemical activity exists. Finally, the abrasive garnet should be ferrite-free, containing no soluble impurities and ofcourse no radioactive radiation should emanate from him.
