Garnet is an inert and recyclable natural mineral that poses no health or environmental risks. The Almandine grains are the heaviest and most resilient of all the garnet grains, giving them the ability to withstand high cutting speeds as well as produce low dust emission levels.
Garnet is environmentally and operator friendly. It can be considered as an alternative to silica sands and minerals slags. Garnet particles are dense, hard and sharp, and free of heavy metals or toxic components. The low friability of garnet permits recycling up to 8 times and the relatively high density ensures fast blasting speeds.
These qualities make Garnet an ideal choice for blasting applications. Applications include cleaning, descaling and surface preparation of structural steel fabrications in the oil, gas, petrochemical and shipyard industries prior to coating application, stainless steel and duplex blasting without ferrous contamination prior to coating, surface preparation of aluminium and fiberglass ship hulls prior to painting, as well as maintenance blasting of chemical plants, pipelines, mining equipment, power stations, petrochemical plants, gas tanks, rail and road bridges, masonry, etc.
They are typically packed in 25kg bags, or 1 metric ton bulk bags.
