Tire Recycling Magnetic Separator for Steel Wire Recovery

Steel wire is first exposed by tire size reduction such as shredding, rasping or granulation. Once the steel is sufficiently liberated, a magnetic separation stage can remove the ferrous fraction from the rubber stream. The suitable separator depends on wire condition, steel loading, feed presentation, working distance and the required result.

Not effectively while bead wire or reinforcement remains mechanically locked inside thick or intact rubber. Mechanical extraction or additional size reduction is normally required before magnetic separation becomes a useful downstream process.

A tire debeader mechanically extracts bead wire from an intact or partly processed tire. A magnetic separator works downstream after enough steel has been exposed so that liberated wire or ferrous fragments can respond as a separate magnetic fraction.

The answer depends on what the shredding stage produces. Frequent long liberated wire on a conveyor can justify a self-cleaning overband. Lower intermittent ferrous loading may suit a suspended magnet. Smaller liberated wire in controlled downstream rubber feed can justify a magnetic drum or polishing stage.

Review an overband when exposed steel travels on a conveyor, the capture load is frequent and continuous automatic discharge is preferable to repeated manual cleaning. Belt width, speed, burden depth, working distance, discharge space and wire-wrapping risk still need to be checked.

A magnetic drum is most relevant when smaller liberated steel wire or ferrous fragments can be distributed across a controlled width and the line can create separate magnetic and non-magnetic discharge paths. Feed depth, working distance, drum speed, splitter position, wear and wire wrapping are part of the design review.

Use a representative sample under recorded feed and separator conditions, collect the magnetic and rubber fractions separately, and measure steel recovery, residual steel, rubber carryover and recovered-steel cleanliness as separate results. Do not compress all four into one undefined efficiency percentage.

Send the process stage, rubber particle-size range, wire condition and liberation, approximate steel loading, normal and peak throughput, belt or chute dimensions, burden depth, available space, discharge arrangement, representative photos or video, and the result you need to measure. A current line drawing is especially useful.
