Garnet Abrasive – Production, Uses and its Benefits

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.

Preventing Silicosis and Deaths From Sandblasting

Because silica sand is commonly used in this process, workers who perform abrasive blasting are often known as sandblasters. Tasks performed by sandblasters include the following: Cleaning sand and irregularities from foundry castings; Cleaning and removing paint from ship hulls, stone buildings, metal bridges, and other metal surfaces
