Introducing Automated Flow Control for Vibrating Screen Feeders

J&H is taking vibrating screen feeder performance to the next level by integrating the benefits of our electromechanical modulating control valve with our static-body vibrating pan feeder.

Traditional first-generation screen feeders relied on manual deflectors at the inlet to adjust material flow and optimize distribution. Our latest solution provides local or remote control of material flow through an electrically actuated bucket valve.

The result? More consistent material distribution across the full width of the screening machine, helping improve screening efficiency and overall feeder performance.

This modulating flow control solution is especially valuable for plants with:

  • Restrictive feed chute geometry
  • Inadequate vertical chute height
  • A need for precise, adjustable material flow
  • Remote flow-control requirements

The J&H Conveying Feeder is a low-profile solution for plants where vertical space is limited. Lower-frequency 900–1,200 RPM vibrator motors convey material along shallow-angle troughs while transforming a concentrated stream into a full-width, uniformly distributed bed of material.

Uniform distribution improves the efficiency, capacity, and wear life of downstream equipment, including:

  • Screening machines
  • Crushers
  • Lump breakers
  • Sorters
  • Other equipment requiring a controlled, evenly distributed feed

The inlet flange can be sized to match the upstream screen discharge, creating a compact connection with minimal vertical drop. Flexible connections accommodate feeder movement, while J&H-developed rubber buffers isolate vibration from the plant structure. Full-width covers provide convenient access for inspection and maintenance.

Key Advantages

  • Low-profile conveying for space-restricted layouts
  • Full-width, uniform material distribution
  • Improved downstream equipment utilization
  • Reduced uneven loading and concentrated wear
  • Isolated vibration and flexible connections
  • Application-specific sizes and configurations

The J&H Conveying Feeder is ideal for transferring oversized material from primary screens to crushers on the level below—and for any application where better feed distribution means better process performance.
