How a Sandblaster Works

Beginners are always asking me, how does a sandblaster work?  So I created this page to help you understand.

A sandblaster works by having compressed air, supplied from an air compressor to power or blast the abrasive media out of a hose from a connecting starting tank.

Depending on the sandblaster, the tank can be an open or enclosed container.  To control the amount of abrasive being blasted, a nozzle is placed at the end of the hose.

There are also adjustments to be made for to control the amount of pressure is used to power the blasting.  You can adjust the air compressor regulator to your desired blasting pressure.

The higher the pressure, the faster the blasting rate will be.  Too high of a pressure may damage your item and it depends on the material hardness and the grit used.  The hardness of the girt can also be a factor.
