Vacuum blasting
Vacuum blasting is an abrasive blasting method,[1] also referred to as dustless blasting or closed loop abrasive blasting.[2] The method is characterized by a blast tool that does abrasive blasting and collects both used blast media, and loosened particles from the surface to be treated, simultaneously.[3]
Procedure
[edit]The blast tool is equipped with a blast hose and a suction hose, that both run from the blast tool to a control unit. The control unit supplies the blast tool with pressurized air mixed with blast media, and sucks back dust, loosened particles and used blast media.[citation needed]
The control unit continuously separates dust and loosened particles from the used blast media, and sends used blast media back into the pressurized air flow.[3] The dust and loosened particles are collected in a waste container.[1]
Applications
[edit]The method is typically used in areas where dust and spill from regular abrasive blasting is not wanted, for example due to HSE-considerations.[4][5] The blast process itself is slower than regular abrasive blasting, but requires less sheeting and scaffolding [6]
