NAVCO Electric Bin Vibrators -also known as unbalanced motors or electromechanical vibrators – are ideal for use on vibratory pan feeders, trough feeders , and tube feeders in handling dry bulk solids materials. They provide high capacity, short distance conveying for storage discharge, stockpile reclaim, crusher feeding, spreading, batching, screening, and separation. NAVCO Electric Bin Vibrators are commonly used in aggregate, cement, coal, manufacturing, recycling, and construction industries.

When using electromechanical vibrators for bin discharge, a channel mush be used for reinforcement when mounting. The reinforcement channel should extend the full length of the sloped section of the storage vessel. A plate may be welded to the channel and machined to the bolt hole specification of the vibrator. Electric Bin Vibrators should be mounted in the bottom 1/2 to 1/4 of the sloped section (cone). They can be paired with digital or pneumatic timers for user-defined sequencing and programmable on/off times.

About Unbalanced Motors

To ensure linear vibrations on longitudinal conveyors, such as trough feeders or vibrating screens, at least two unbalanced motors with counter-rotating directions are required. Devices with torsional vibration require drives with the same direction of rotation. Cross vibration monitoring is used to ensure proper rotation at all times.
