Easy to add to any bin, silo, or hopper whether new or existing.

Bulk load, activate, and control flow.

Motor controls choices for material flow rate control include a conventional VFD or pneumatic system for the mechanical modulation of feeder wheel centrifugal weights.

Vertical material discharge to underlying belt conveyor provides uniform loading and eliminates belt tracking problems.

Impact idlers are not required for the product take-away conveyor.

Adjustable baffles minimize material wedging, compacting, and bridging common to conventional large opening bin or pile activators.

Rectangular low headroom design allows for simple hopper designs and reduces installation costs. Flanges on inlet and outlet allow for ease of sealing with no material contact of seals.

Balanced design with isolation springs minimize the transfer of dynamic loads to support structures / foundations
Large hopper openings for high capacity material reclaim means fewer units are required for a given production requirement.

Two-mass natural frequency or direct-drive configurations.

Increases system efficiency with consistent product flow to downstream equipment.

Unit can function as a metering flow splitter.

Durable with minimal moving parts.

Common unit sizes: 4’x4’ (1.2mx1.2m) , 5’x5’ (1.5mx1.5m), 6’x6’ (1.8mx1.8m), 7’x7’ (2.1mx2.1m), 8’x8’ (2.4mx2.4m), 9’x9’ (2.7mx2.7m)

Typical Materials

Typical bulk materials that will free flow with the transmission of vibratory energy from a storage pile :

  • Size Reduced Bulk Materials
  • Coal
  • Aggregates
  • Earth
  • Sand
  • Crushed Concrete
  • Chips
  • Sawdust
  • Granular Food Products
  • Chemicals
  • Glass
  • E-Scrap


  • Under silos, hoppers, stockpiles, bins, or barn type storage
  • Rail mounted bulk loading and reclaim systems
  • Mines with below grade installation in tunnels
  • Above crushers
  • Underneath hoppers with dump truck or mass loading
  • Unloading and loading of bulk materials at ship loading terminals
  • Power plants, especially mass-flow handling of coal
