Bridging
Material forms a stable arch above the outlet and stops discharge.
APPLICATION 06 / Silos + hoppers
RVS™ resonance for silos and hoppers.
RVS™ resonance for silos and hoppers.
Break the bridge. Restore the flow.
Pneumatic silo and hopper vibrators transfer excitation into the vessel wall to support bulk-solid discharge. RVS is assessed for bridging, ratholing and wall build-up; the result depends on the material, hopper geometry and mounting. A pilot compares discharge consistency and blockage frequency before and after installation.
FrequencyUp to 800 Hz
ForceUp to 25,000 N
DrivePneumatic
RangeStationary / Immersible / Custom
VISUAL USE CASE / SILO CONE
Break the stable bridge.
RVS units transfer resonance into the cone near the outlet, where cohesive material commonly forms arches or adheres to the wall.
- Problem
- Bridging, rat-holing and interrupted bulk-solid discharge
- RVS role
- Mobilize material through the silo wall at the restriction
- Target
- Reliable flow and faster recovery from blockage
Treat the discharge problem at its source
A silo can contain plenty of material while the outlet receives almost none. Bridging, rat-holing and wall adhesion are shaped by material properties, moisture, vessel geometry and operating history. RESONATOR focuses vibration on the active failure zone instead of shaking the entire structure without a defined objective.
Typical process challenges
Every installation begins with the actual material, equipment and measurable production problem—not a generic device selection.
Rat-holing
A narrow channel empties while product remains stationary around it.
Wall adhesion
Fine, damp or cohesive material accumulates on internal surfaces and reduces usable capacity.
ENGINEERING METHOD
How RESONATOR responds
Frequency, force, mounting and timing are treated as one engineered operating system. The final configuration is validated under representative conditions.
- 01
Diagnose the pattern
Document where flow stops, how often it occurs and what operating conditions trigger it.
- 02
Review vessel geometry
Assess cone angle, outlet size, wall material, supports and structural transfer paths.
- 03
Select the excitation point
Place controlled vibration near the failure zone with a suitable mounting method.
- 04
Tune by discharge
Adjust the operating window while measuring flow continuity, residue and cycle time.
Potential process outcomes
These are engineering objectives, not automatic guarantees. Performance depends on the material, structure, operating point and validation method.
Reliable discharge
Supports material movement through the outlet and reduces recurring flow stoppages.
More usable capacity
Reduced wall build-up can help recover material that would otherwise remain in the vessel.
Less manual clearing
A defined vibration sequence can replace improvised striking or repeated operator intervention.
System fit
Choose the energy-transfer route that fits the process environment and access point.
Stationary
Primary solution for external mounting on suitable cone, wall or support locations.
Immersible
Specialized option where internal placement is justified and compatible with the stored material.
Custom
Engineered multi-point layouts for large vessels, difficult geometry or changing products.

Questions about this application
Can a silo vibrator help with hopper bridging and ratholing?
Vibration can help mobilize material near a restricted outlet or wall. However, the outcome depends on cohesion, moisture, outlet geometry and mounting. Too much excitation can compact some materials, so a silo vibrator is selected through a material-specific trial.
Where is an RVS silo vibrator installed?
An engineered interface transfers excitation into the wall or supporting structure near the resistance point. Position and mounting must be reviewed for the actual vessel; the application drawings are concepts, not installation instructions.
