Garnet Sand
Garnet sand is a general mineral and not a by-product of a chemical process. It is inert and non-toxic and virtually free of silica, thus excluding any danger whatsoever of silicosis hazard. it has a very low dust emission. This makes it safe for the operator, does not pollute the atmosphere In consequence, garnet as an abrasive has worldwide support among occupational health authorities.
Garnet Sand Abrasive
Moreover, as Low Dusting. Better Visibility. Safe to Use. Abrasive garnet sand is 100% natural, non-ferrous inert mineral containing less than 1% free silica and no detectable levels of heavy metals. Our garnet poses little or no health or environmental risks. Garnet produces less dust than many other blast abrasives resulting in improved visibility, less disruption to adjoining work areas and safer working conditions. is an environmentally friendly material.
The selection of abrasive media for blast cleaning steel is based primarily on two broad objectives, quality and economics. Quality is defined in terms of appearance after cleaning, profile depth and contour, and chemical cleanliness. The economics of an abrasive is determined by its initial cost and by the production rate that can be achieved when it is used.

Garnet sand does not pollute the atmosphere because it has very low dust emissions. Therefore it offers no known health hazard. When it has used in offshore areas, does not contaminate or foul the sea-bed nor disturb marine life. Due to its high productivity, less garnet sand is used and therefore less cleanup. As garnet sand could be recycled many times and also being a natural non-toxic mineral, it does not Create disposal problems as other slag abrasives do.
