Total recovery with masonry works

A floor completely made up of perforated and suitably reinforced sheet metal panels overlies three or more tanks positioned in excavations made in the floor (height -250mm from floor 0). This solution makes it possible to have the booth floor level with the external floor (thus avoiding any steps or differences in level at the entrance to the booth, thus facilitating the insertion and extraction of blasted parts).

This Protech recovery system involves the use of an adequate number of longitudinal and transversal scrapers, characterised by numerous trolleys joined together with anti-vibration supports, which run on rocker arms with resistant nylon double wheels, complete with 2RS bearings (instead of single, dowelled wheels).

Each trolley is then equipped with anti-abrasive rubber combs, which guarantee optimal transport and recovery of all the abrasive used (avoiding unnecessary waste of material on the ground) since, during the sandblasting cycle, the rubber bands slide flush to the floor without the friction, vibration or annoying noise that is usually generated by systems that mount iron scrapers. Iron scrapers, in fact, are usually kept about 1 cm from the abrasive falling surface, thus creating unnecessary waste of material, and therefore increasing costs for the user (in proportion to the cost of the abrasives used), as well as generating annoying vibrations and noise.

In terms of movement, each Protech scraper is driven by a low-consumption gear motor (IE3 motors) that guarantees safe and constant operation of the recovery system.

Finally, the scrapers are protected by cover gratings, to which perforated plates are added to make the gratings themselves more protective for the scrapers (also increasing their capacity).

The purification of all the abrasive recovered from the ground is guaranteed by a selector with a rotating sieve, and characterised by 4 stages of cleaning and selection of the abrasive to be put back into the blasting cycle.
