Product Overview The Electromagnetic Vibrating Feeder is a precision material handling device traditionally employed in metallurgical and industrial processes for controlled feeding of bulk solids. While gradually being superseded by modern belt feeders in some applications, this equipment remains relevant in scenarios requiring ultra-fine material control, high-frequency operation, or compact installations. Compliant with GB/T 13306-1991 and GB/T 755-2008 standards, it serves as a cost-effective solution for low-to-medium capacity systems where material degradation must be minimized.

Design Features

• Precision Control: Micro-adjustable vibration intensity for delicate material handling.
• Zero Material Contamination: Non-contact drive mechanism eliminates lubricant risks.
• Compact Footprint: 30–50% smaller than equivalent belt feeders.
• Low Maintenance: No rotating parts except exciters; simplified lubrication points.

Typical Applications

• Batch dosing in induction furnaces (metallurgical plants).
• Powder injection systems for alloy production.
• Legacy cement kiln feed systems.

Limitations & Transition Guidance While reliable for precision tasks, this feeder type exhibits higher energy consumption (~15–20% more than belt feeders) and limited suitability for sticky or ultra-fine (<0.5 mm) materials. For modernized operations requiring energy efficiency or large-scale throughput, we recommend transitioning to belt feeders (see our Belt Feeder Series).
