Selecting the correct magnet size is not about choosing the largest diameter — it is about matching lifting capacity with excavator hydraulic power and operational needs.

Key factors to evaluate:

1. Scrap Density

Loose shredded scrap requires different magnetic force compared to heavy HMS bundles.

2. Excavator Tonnage

Magnet diameter must align with the excavator’s lifting capacity to avoid imbalance.

3. Power Supply

Voltage and duty cycle determine holding strength and operational consistency.

4. Duty Cycle Requirements

Continuous loading operations require Class H insulated coils to prevent overheating.

A properly matched system ensures:

• Stable lifting

• Reduced wear

• Longer equipment life

• Maximum efficiency per cycle

Oversizing or undersizing directly impacts productivity and safety.
