Questions and Answers

Find answers to our most frequently asked questions.

What causes bridging or ratholing in a hopper or silo?

Material can form a stable arch (bridging) or a narrow vertical channel (ratholing) that blocks consistent flow, usually due to moisture, particle size, or compaction. Targeted vibration breaks up the structure and restores flow. Learn More

What feed rates can a vibratory feeder handle?

Rates scale from fine, precise dosing (like seasoning applications) up to several tons per hour, depending on the model and tray configuration. Learn More

Can vibratory feeders handle fragile or delicate products?

Yes. Gentle, controlled vibration moves product without the impact or throwing motion of belts or augers, which is why feeders are widely used for foods like chips and other easily damaged items. Learn More

How is a vibratory feeder more accurate than manual filling?

Amplitude and frequency are directly adjustable, so the feed rate can be tuned to an exact target and repeated consistently, unlike hand-scooping, which varies from batch to batch. Learn More

How accurate is vibratory dosing compared to manual scooping?

Vibratory systems remove the variability of hand-scooping, delivering consistent, repeatable doses at the touch of a button or foot pedal, with less product waste and fewer repetitive-motion injuries. Learn More

Can vibratory dosing handle individual pieces, not just powders?

Yes. The same amplitude-and-frequency control that meters bulk powders also works for discrete items like pills, small hardware, or mechanical parts. Learn More

What’s the difference between loss-in-weight and volumetric dosing?

Loss-in-weight dosing measures the actual weight dispensed and stops at a target weight, ideal for high-precision batching. Volumetric dosing meters a set volume per cycle, which works well for consistent, free-flowing materials at high speed. Learn More

Will compaction damage fragile products?

No, when amplitude and frequency are set correctly. Compaction tables are used routinely on food products like frozen broccoli, where gentle settling — not impact — does the work. Learn More

Can compaction tables handle liquids, not just solids?

Yes. Thick or viscous liquids, like melted chocolate, can be de-aerated and evenly distributed using the same vibratory principle before cooling or packaging. Learn More

Why does vibration work better than manual settling or tapping?

Manual methods are inconsistent and can damage product. A compaction table applies controlled, repeatable vibration at a set amplitude and frequency, so every container settles the same way, every time. Learn More
