The basic partial recovery system involves a hopper - at floor level or raised above the floor - into which the abrasive deposited on the cabin floor during blasting operations is manually conveyed.
Once directed into the hopper, the abrasive is collected by a bucket elevator that feeds it into the recovery and purification circuit for cleaning, storage and subsequent reuse inside the blasting machine.
The purification of all the abrasive recovered from the floor 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.
