A vibrating feeder is a mechanical device designed to transport or feed bulk materials in a controlled and consistent manner within industrial processes. It is widely used in handling granular, powdered, or fragmented materials.

Components:

  1. Tray or Chute: A horizontal or inclined surface (often made of steel) where materials move.

  2. Vibration Generator: Electromagnetic drives or motor-driven eccentric weights to create vibrations.

  3. Springs (Coil or Leaf): Isolate vibrations from the supporting structure.

  4. Control Unit: Adjusts vibration amplitude and frequency to regulate feed rate.

Operating Principle:
The vibration generator produces oscillatory motion, causing the tray to vibrate. This vibration induces micro-throws in the material, propelling it forward. By adjusting the amplitude (stroke) and frequency, the flow rate can be precisely controlled.

Applications:

  • Mining (ore feeding to crushers),

  • Cement and chemical plants,

  • Recycling facilities (sorting and conveying),

  • Food processing (handling grains or powders),

  • Automated assembly lines (component feeding).

Advantages:

  • Precision: Instant flow rate adjustment via vibration controls.

  • Low Maintenance: Minimal wear due to few moving parts.

  • Versatility: Compatible with abrasive, hot, or sticky materials.

  • Energy Efficiency: Consumes less power compared to belt conveyors.
