Garnet Abrasive
china garnet abrasivesand is made of garnet raw materials after crushing and screening. It is an island-like structure of aluminum (calcium) silicate, which has the characteristics of high hardness, strong grinding force, acid and alkali resistance, and high-temperature resistance. Garnet sand is primarily used for water jet cutting, sandblasting, and water purification media.

Typical Physical Properties of Garnet Abrasive
Sand Blasting
Garnet abrasive's hardness is moderate and has high bulk density. It have free silica and good toughness. It is the ideal "environmentally friendly" sand blasting material.
Free Grinding
The Grinding grade garnet abrasive is applied to the picture tube, optical glass, monocrystalline silicon, lenses, watches and clocks, glass, crystal glass, jade and other fields of free grinding. It is widely used in domestic advanced abrasive materials.
Resin Grinder
Garnet abrasive with the right color, good hardness, toughness, and be suitable for the type of particle cross-section and blade retention. It can be used as a substitute for 20%-30% filler corundum resin grinding tool.
Coated Abrasives
Garnet abrasive are materials production of paper, gauze and other manufacturers of raw materials production.
Functional Filler
The garnet will be used mainly to automobile brake parts, special tires, special building products, etc., and can be used to the construction of the highway pavement, the runway, the wharf, the parking lot, the industrial floor, the sports field, etc.
Filter Media
Filter media Is a new application field of garnet, the underlying medium using granular garnet filtrating bed can clean drinking water and wastewater. It is a new type of filter material, especially suitable for non-ferrous metal processing, and oil drilling mud weighting agents.
Water Jet Cutting
Based on garnet abrasive cutting medium, rely on high pressure water jet cutting in basic and apply in oil (gas) cutting pipe, steel etc. It is a new type, environmental protection, safe way to cut.
