By vacuum suction both the abrasive agent and the removed material and dust is sucked up [2] and then separated from each other. The dust is collected in a container, and the abrasive agent is returned to the tank to be reused in a cyclic course. Vacuum shot blasting Process films Advantages and disadvantages In comparison with alternative methods Wide range of abrasives No need for costly safety measures Meets environmental standards Easy to use closed circuit that allows a continuous use of abrasives Less effective on irregular surfaces Ineffective for large surfaces
