Abrasive Blasting Materials The decision to use a certain type of abrasive material can depend on factors such as cost, job specifications, environment, and worker health. Commonly used abrasive materials: • Silica sand (crystalline) • Coal slag • Garnet sand • Nickel slag • Copper slag • Glass (beads or crushed) • Steel shot
When compared to silica sand in this manner, you will find that the costs of some silica substitutes are competitive. The health effects of many of the silica substitutes have not been determined, and the materials removed by abrasive blasting are often very hazardous.
In terms of Quality, Industrial Garnet is much better than slag. In addition, it has no health issues like the silica sand. Due to this, Garnet is now the preferred blasting media. As our Garnet is crushed from hard rock, it will be of higher density, sharper, and wider size ranges suitable for use in various blasting .
Garnet keeps the workers safe – if you are using Slag or Silica Sand you are exposing your workers to many dangers. Silica Sand is a #1 carcinogenic which causes Silicosis (cancer of the lungs). Ever seen someone with Silicosis? If you have, you will never ever allow the use of Silica Sand again – it destroys people''s lives entirely.

In the Netherlands, sandblasting with silica sand has been forbidden already since 1957 and instead of "sandblasting" we now speak about grit or shot blasting, abrasive blasting or blast cleaning. High quality substitutes are widely available: Aluminium Silicate (coal slag grit), Glass Granulates, Olivine and Garnet.
Silica sand is commonly used for abrasive blasting where reclaiming is not feasible, such as in unconfined abrasive blasting operations. Sand has a rather high breakdown rate, which can result in substantial dust generation. Worker exposure to free crystalline silica is of concern when silica sand is used for abrasive blasting.
Sand blasting is much more dangerous to workers than typical glass bead blasting. The afterproduct of sand blasting is called silica dust and can cause silicosis in workers after prolonged inhalation. Because of this, sand blasting is heavily regulated. Conversely, glass bead blasting is much safer because the beads do not produce a silica ...
