Holland Mineraal is a specialist in the design and manufacture of abrasive transport systems, using its own in-house team of engineers. The following blast room systems have been used in various market segments around the world. We have four possible methods at our disposal for the recovery of abrasives:
Sweeping pit
The abrasive mix is swept into a specially constructed well, which is equipped with a cover grille and a metering slide. 
Conveyor Belt
The abrasive mix is funneled to the conveyor belt through special collection hoppers and then removed for reuse. You can choose to employ this system across the full, or partial, width of the cabinet. 
Screw conveyor
The abrasive mix is funneled through special collection hoppers in the collection channel and then removed by the screw conveyor. You can choose to employ the screw conveyor system across the full, or partial, width of the cabinet. 
Scraper floor
In this system, there is a complete grid floor over the entire area of the room. During the blasting process, the abrasives fall through the grid floor and are conveyed by scraper belt to a cross scraper that feeds into the elevator. 
All of the above systems ultimately convey the abrasive mix to the base of the elevator. The elevator is equipped with a belt and bucket system which picks up the abrasive. The abrasive is fed through an outlet at the top elevator onto a special drum sieve and then onto the abrasive cleaner (cascade cleaner). It can then be extracted through the main filter or a separate self-cleaning cartridge filter. The cleaned abrasive mix is collected in the storage bunker and is now ready for re-use.
