Garnet sand is environmentally inert and meets most health and safety requirements. In recent years, this means it has begun to replace other sand blasting materials. Materials like silica, aluminium oxide and steel slag emit toxins and create high levels of dust. This makes them a breathing hazard for industrial workers.
While silica still represents the most common abrasive in most countries, Germany, Belgium, Sweden and the United Kingdom have banned its use. These bans resulted from links between silica use and operator lung disease.
Garnet sand costs somewhat more than silica, which is why it remains less common. However, garnet sand poses little to no health risk as it does not produce excess dust during use.
If you or your company require a sand blasting service, talk to your technician about garnet sand for your next project. This environmentally friendly option can decrease costs and increase efficiency in sand blasting tasks for many industries.
Consider the characteristics discussed above when deciding whether garnet sand is the right abrasive for your specific application.
