Garnet Abrasive Blasting

Garnet sand is an advantageous abrasive, and a prevalent replacement for silica sand in sandblasting. Garnet is used to cutting steel and other materials in water jets when mixed with very high-pressure water. Garnet extracted from hard rock has more angular in form, so it is more suitable for water jet cutting. Therefore, it would be more efficient in cutting.

As an abrasive, Garnet can be broadly separated into two classes, blasting grade and water jet grade. The garnet is crushed to finer grains as it is mined and collected; all pieces which are higher than 60 mesh (250 micrometers) are usually used for sandblasting. The pieces between 60 mesh (250 micrometers) and 200 mesh (74 micrometers) are usually used for water jet cutting. The remaining garnet pieces that are finer than 200 mesh (74 micrometers) are used for polishing glass and lapping. Regardless of the usage, the smaller ones are used for finer finishes and the larger grain sizes are used for quicker work.

Some of the significant benefits of using Garnet Abrasive except quality, safety and cost-savings features, include low dust production which is safer for workers, ideal for restricted spaces, high recycle-ability which is almost 3 to 6 times recyclable depending on the application, high hardness, fast and clean abrasive, low friability, environmentally-responsible, cost-effective and long-lasting.

Garnet is one of the very best abrasive options for many blast shop operations. Some of the benefits are listed below. High Speed, very Low Dust and the lowest Consumption rate compared to conventional abrasives highlight the advantageous of Garnet. Some of the other benefits are listed below.

Extremely hard (8 MOH Hardness) blast abrasive

Very low dust generation

Recyclable up to 5 times

Used for Dry Blasting, Slurry Blasting, and predominately the predominate media for Waterjet
