Traditionally, the SANDBLASTING process is carried out with inert grit such as corundum, glass and ceramic beads, garnet.

Although the term is now used in a generic form, therefore also for applications in whee blast systems (see Shotblasting), sandblasting is normally designed for the use in compressed air systems, whether they are manual cabinets or big cabins, both with pressure system and vacuum (Venturi).

The characteristic fragility of the inert grit entails great production of dust during the process, with consequent significant operational problems (poor visibility and healthiness) but also economic problems, due to the high consumption, excessive disposal and the large wear of the machines (substantial maintenance costs and spare parts).

However, these problems are absolutely negligible with the use of VULKAN stainless steel grit, which has a very low crushing factor.
