Use of Abrasive Garnet Sand?

Mainly for industrial uses, Garnet sand is a good abrasive media, and a common replacement for silica sand in Sand Blasting Machine. Garnet abrasive grains and mesh 80 which are sharpened rounder are more suitable for such blasting handling. Garnet Abrasive Sand is a group of iron aluminum silicate homogeneous minerals having similar properties. Non-hygroscopic has a sharp angular shape, is inert, slightly magnetic, not soluble in water, translucent, friable to tough, and contains no free chemicals. All oxides and dioxides are combined chemically. The iron and aluminum are partially replaceable by calcium, magnesium, and manganese.

Abrasive Garnet Sand Properties

• Almandine: Fe₃Al₂Si₃O₁₂
• Mohs scale hardness: 6.5–7.5
• Other characteristics: variable magnetic attraction
• Specific gravity: 3.1–4.3

It is Mixed with very high-pressure water, Garnet is used to cut steel, and other materials in water jets.

Types of Garnet Sand

There are three types-

• Aluminum garnet
• Iron garnet
• Chromium garnet

Abrasive garnet sand produces a super clean surface finish with a uniform profile that is virtually free of particle embedment. A clean surface finish and uniform profile mean better coating adhesion and longer coating life. Garnet abrasives media are harder, heavier, and more durable than many other mineral blast abrasives. Barton’s garnet abrasives cut faster resulting in rapid job completion with reduced abrasive consumption, handling, and disposal costs, and are ideally suited to recycling; typically providing three to five turns, making it one of the most economical mineral abrasives on the market.
