Electromagnetic Separation System

• A rectifier cabinet converts 380V AC to DC220V power.

• This power energizes the excitation coils.

• The coils generate powerful, directional magnetic fields.

• These sophisticated electricity magnets utilize DT4 magnetic poles.

• The poles form highly efficient closed magnetic circuits.

• This maximizes separation efficiency for the overbelt magnetic separator.

• Ferrous materials are effectively extracted from conveyed bulk loads.

Oil Circulation Cooling

• Heated oil is pressurized through a dedicated circulation system.

• It flows into tubular condensers for cooling.

• Axial fans provide forced air cooling (air volume ≥3000m³/h).

• This advanced thermal management is critical.

• It maintains optimal operating temperatures for the overbelt magnetic separator.

• Oil temperature differentials are controlled within 8°C.

• This ensures consistent, reliable performance.

Automated Cleaning Process

• Captured ferrous materials are continuously transported.

• This is done via the cleaning belt to designated collection points.

• A PLC system automatically initiates cleaning cycles.

• Cleaning intervals are adjustable (15-60 minutes).
