| 摘要 |
A device (33) for blast-machining or abrasive blasting objects such as structural elements, tools, household objects, pots, pans or the like, has a blast pot (3) for holding a blasting abrasive (35) which is connected via at least one line (21) to a blasting nozzle (24) which extends into a blasting space (1) in which the objects which are to be blasted can be placed. Compressed air is introduced above the blasting abrasive mixture (35) provided in the blast pot (3) by means of a pressure-generating means (43) and the blasting abrasive (35) thus being forced into the blasting space (1), the compressed air conveying via a second line (10) the granular material or the granular material mixture (35) and/or a suspension formed from granular material and liquid out of the blasting space (1) and back into the blast pot (3), which also takes the form of a pressurized space.
