What is Garnet Abrasive ?

Garnet abrasive is mined from almandite and andradite mineral deposits in Australia, and India. In its natural state, garnet is a semi-precious stone. Once extracted, it is washed, processed and screened to the necessary grade for use as an abrasive

Rock garnet is perhaps the garnet type used for the longest period of time. This type of garnet is produced in America, China and India. These crystals are crushed in mills and then purified by wind blowing, magnetic separation, sieving and, if required, washing. Being freshly crushed, this garnet has the sharpest edges and therefore performs far better than other kinds of garnet. Both the river and the beach garnet suffer from the tumbling effect of hundreds of thousands of years which rounds off the edges.

Garnet has been mined in western Rajasthan in northwestern India for the past 200 years, but mainly for the gemstone grade stones. Abrasive garnet was mainly mined as a secondary product while mining for gem garnets and was used as lapping and polishing media for the glass industries.

Grade of Garnet Abrasive Blasting Media

Types – the most common types are Australian Garnet, and Indian Garnet

Grades – our most popular grades are 12/24 , 20/40 , 20/60 and 30/60 mesh.

Uses of Garnet Abrasive

Garnet abrasive is most commonly used as a high-performance blast media, for the cleaning of aluminium and fibreglass structures. Because it is an inert, non-toxic, naturally-occurring mineral, garnet abrasive is also used on sites where water contamination is a concern, such as dry docks, bridges and harbours.

Garnet abrasive does not produce as much dust as other expendable abrasives, making it particularly suited for use in such confined spaces as tanks and containers.

Benefits of Garnet Abrasive Blasting Media

Clean – Garnet abrasive produces less dust than other expendable abrasives, making it ideal for use in tanks and other confined spaces.

Cost-Effective – Garnet abrasive lasts a long time, and is so effective that lower volumes overall are required for most jobs.

Garnet Abrasive is semi reusable and can be re-used several times under correct conditions. It does break down quicker than fully re-usable abrasives such as aluminium oxide.

Optimum Surface Profile – garnet abrasive creates a superior surface for adhesion coating.

Environmentally Friendly – Garnet is inert and non-toxic, making it safe for use around bodies of water. It is also very easy to clean, whilst its durability reduces the generation of dust.

The environmental advantages of garnet lie in three aspects:

Less dust

When we use garnet sand in surface blasting, since garnet sand has a high specific weight, it generates less dust during blasting process, which guarantees safety of operators and improves visibility. In comparison, quartz sand is a kind of abrasive that is easy to be broken. During blasting process, it will produce large amount of harmful gas and hydrated silica dust polluting the environment. Once taken in by human, these dust may cause cancer.

Environmental protection

Different from conventional blasting materials, garnet sand is a kind of non-toxic natural mineral. Low consumption and recycling can also help reduce waste.

Recyclable

Garnet sand can be used in a variety of fields. Generally, it can be reused five times and more. When garnet sand loses its cutting capacity, it can be used as cement additive in construction industry.

 

Excellent For:

Tanks and other confined spaces where use of a low dusting abrasive is necessary.

Dry docks, Bridges, Shipyards – a great abrasive to use where water contamination is a concern.

Aluminum and Fiberglass surfaces

Hangar decks

Powder Coating

Denim blasting

Industrial Painting
