Single Screw Partial Reclaim System

A single screw partial reclaim system is the most economical floor design available. The system contains the major components found in all Hoffman Blast Room Equipment reclaim systems including metering shed plates, heavy-duty screw, belt and bucket elevator, 20" airbrush separator, perforated plate rotary drum separator and over sized abrasive storage hopper with a caged man ladder and handrail. This is a basic "automatic" reclaim package that can be expanded to an H, U, or Full Floor reclaim system. It is best suited for low to medium production levels.

H - Shaped Partial Reclaim System

The H shaped partial reclaim system adds two longitudinal metered screw assemblies along each side wall of the blast room. The position of the screw assemblies allow the abrasive delivered from the blasting nozzle, which is either blown or rebounded off the work piece, to strike the side walls and fall into the screws; automatically reclaiming approximately 60-90 percent of the blast media. The remaining abrasive on the floor is pushed into the metered shed plate screw assemblies at the end of the work shift. The H shaped floor design is typically utilized in a "flow-thru" room configuration where heavy work pieces, and/or material handling devices can drive into the room and position the work piece on the steel covered concrete floor located between the screws. This system is best suited for medium to high production.

U Shaped partial Reclaim System

The U shaped partial reclaim system adds two longitudinal metered screw assemblies along each side wall of the blast room and positions the cross screw along the back wall of the blast room. The position of the screw assemblies allow the abrasive delivered from the blasting nozzle, which is either reblown or rebounded off the work piece, to strike the side walls and back wall of the blast room and fall into the reclaim system. A U shaped floor design will automatically reclaim 60 to 90 percent of the blast media. The U shaped floor design is typically utilized in an "in-out" room configuration where heavy work pieces and/or material handling devices can drive into the room. This system is best suited for medium to high production.

Full Floor Reclaim System

The Full Floor Reclaim System utilizes multiple screw assemblies to create a fully automatic abrasive system, where 100% of the blast media is returned to the separator system during the blasting operation. The full floor reclaim design requires that the material handling of the work piece be intricately designed into the configuration of the room. The full floor reclaim system can be used with any room configuration. This system is best suited for high production requirements.
