    How Does A Sandblaster Work? - Sandblasters, Sand Blasting ...

    All sandblasters work on roughly the same principles: finely ground silica sand is used to clean and abrade a surface, typically metal, of any rust, paint or other unwanted surface materials. This is done by means of an air-powered pressure gun that fires out the sand at high velocity to impact with the intended surface. All sandblasters use said pressurized gun, which has a ceramic barrel or ...

    Aeolian erosion was accomplished by utilizing the Venturi principle in a specially designed sand blasting device (Figure 1). A controlled flow of gas was metered into the apparatus creating a pressure differ-ential in the Venturi tube which picked up sand from a reservoir. The sand was then accelerated through the nozzle and directed at a test disc
