Garnet as a natural abrasive can be used for waterjet cutting because of its high hardness, high cutting speed. It is a cost-effective alternative to silica sand, mineral slags and steel grits and shot as the perfect symbiosis of grain size, density and hardness/durability creates the optimum abrasive efficiency, lowest abrasive consumption (kg/m2) at the highest production rates (m2/hr). Compared with rock garnet, river garnet sand can keep the cutting surface smooth and flat. Because river sand is formed after a long time of impact, so its grain edge surface is more rounded, less damage to the material. Products cut from river garnet are more popular with consumers. -Sharpe Angular Edges; -High Hardness, Faster Cutting Efficiency; -Uniform Size Distribution, No Stuck in Nozzle; - No Free-Silica.
