Blasting medium does not only fall on the floor; in a ship section, bridge section or lock gate, blasting is also done in the hollow spaces of the structures. With the vacuum recovery installation from Straaltechniek, the abrasive can be recovered easily and effectively in these places.
Above the conveyor belts you will see a small cyclone. This separates the abrasive from the dust. The blasting medium falls from the bottom of the cyclone onto the conveyor belt. The dust remains mixed with the air and this air is returned to the vacuum cleaner, where it ends up in the filter.
