Total recovery

Total recovery without masonry works

A floor consisting entirely of suitably reinforced perforated sheet metal panels overlies tanks located above the '0' level, making it possible to avoid any masonry work (height +250mm from the '0' level).

This Protech recovery system involves the use of an adequate number of longitudinal scrapers and one transversal one, 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 studded 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 strips run flush with 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 robust cover gratings, to which perforated plates are added to make the gratings 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.

In stainless steel shot peening plants, the selector is made of stainless steel, the selection is pneumatic and - before storage in the silo - the abrasive passes through a magnetic grid that retains any ferrous impurities.
