Abrasive blasting Wikipedia

Vacuum blasting is a method that generates very little dust and spill, as the blast tool does dry abrasive blasting and collects used blast media and loosened particles from the surface to be treated, simultaneously. Blast media consumption is relatively low with this method, as the used blast media is automatically separated from dust and loosened particles, and reused several times.
