Garnet Abrasive
Garnet mineral is one of the minerals of silicates group. It is obtained by grinding garnet rock that is in nature of 98 percent pure form. Hardness of it comes after diamond and corundum. It's hardness is between 7,5-8,5. It is known as Australian garnet and Indian garnet in the market. Garnet abrasive is composed of natural Almandite garnet grains that are known for their natural hardness, durability and abrasive characteristics. It is an 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).

Being environmentally inert, Garnet meets all Occupational Health and Safety requirements and achieves the highest quality of processing standards in respect of mineral purity and the stringent international requirements for chloride and free silica content. In addition, Garnet abrasive is recyclable up to 5 - 10 times (depending on the application) due to its superior toughness and low friability. Garnet is used as a sandblasting cleaning abrasive in various industries around the world and is approved by major oil companies, shipyards and major paint manufacturers.
It is suitable for all areas of surface preparation especially stainless steel, anti-magnetic steel and all specialty alloys as it is free of metallic iron. Blast cleaning using Garnet provides significantly lower dust emissions due to its inherent material toughness and rapid settling (high specific gravity). This ensures minimum disruption and danger to adjoining operations and improves operator visibility and safety. Very fast cutting is achieved with speed, large number and shape of grains impacting on the surface. The acceleration and speed of a grain in an air stream is a function of the inertia and hence the size of the grain. The unique grain size enables many more active grains impacting the surface and greatly reduces abrasive consumption. Garnet grains clean deep into the cavities and pitted areas down to the bare metal, thoroughly removing all rust, soluble salts and other contaminations. The blasted surface is free of embedment and rogue peaks and troughs. SA3 White Metal is effortlessly achieved. Garnet is non-toxic with no silicosis hazard or risk of contamination from leachable heavy metals or radioactive substances.
