Vibrating feeder

Equipment that meters bulk material from a hopper to a conveyor, screen or crusher at a controlled, continuous rate. Types: electromagnetic (amplitude-controlled, 0–100%), eccentric mechanical and grizzly (with bars for pre-classifying coarse rock). Capacities: 5–2,000 t/h. Reduces choking and load peaks in downstream equipment. Brands: Eriez, General Kinematics, Metso.

Full definition

Vibrating feeders are critical components in bulk material handling systems, particularly in the mining industry. They are designed to transport bulk materials from a storage hopper to downstream equipment such as conveyors, screens, or crushers at a consistent and controlled rate. This ensures that the downstream processes receive a steady flow of material, which is essential for maintaining operational efficiency. Vibrating feeders operate by utilizing vibrations to induce movement in the material, allowing it to flow smoothly without clogging or hindering the process. The amplitude and frequency of these vibrations can be adjusted to suit the material characteristics and desired flow rate.

What you need to know

  • What you need to know:
  • Vibrating feeders can handle capacities ranging from 5 to 2,000 tons per hour (t/h), making them suitable for various scales of operation.
  • Three main types of vibrating feeders are electromagnetic, eccentric mechanical, and grizzly, each suited for different material handling requirements.
  • Electromagnetic feeders allow for precise control of material flow by adjusting amplitude from 0 to 100%, offering flexibility in operations.
  • Grizzly feeders are specifically designed with bars to pre-classify coarse rock, reducing the load on downstream equipment.

Industrial applications

  • 1Used in mining operations to regulate the flow of materials from hoppers to crushers, enhancing processing efficiency.
  • 2Applied in aggregate processing plants for separating and feeding materials to screens and conveyors.
  • 3Utilized in recycling facilities for the controlled feeding of mixed materials into shredders or granulators.

Common mistakes

  • Overloading the feeder can lead to uneven material flow and potential damage to downstream equipment.
  • Failing to adjust the feeder's amplitude and frequency settings according to the material characteristics may result in inconsistent feeding.
💡

Pro tip

Regular maintenance and cleaning of the feeder can prevent material buildup, ensuring optimal performance and longevity.
