Silo Vibrators and Material Flow Solutions

Silo vibrators help bulk materials move consistently through storage and processing systems by reducing bridging, rat holing, sticking and restricted discharge. Vibration Systems supplies electric and pneumatic silo vibration systems for Australian industrial operations. We assess the stored material, silo construction, discharge arrangement, operating environment and required duty before recommending suitable equipment, mounting and controls.

Improve Material Flow Through Silos


Powders, granules and other bulk materials can compact or adhere to the internal walls of a silo. Changes in moisture, particle size and storage time can also affect how the material behaves. When flow becomes inconsistent, production may slow and operators may need to intervene more frequently.



Correctly selected silo vibrators transfer controlled vibration into the structure to encourage material movement. The required vibration force and frequency depend on the material and the silo. Our team can help determine whether an electric vibrator or a pneumatic rotary vibrator is more suitable for the application.

Common Silo Flow Problems


Silo flow aids may be considered when an operation experiences:

  • Material bridging above the outlet
  • Rat holing through the centre of the stored material
  • Product sticking to internal surfaces
  • Slow or irregular discharge
  • Compacted material after extended storage
  • Frequent manual clearing



The cause should be assessed before equipment is selected. Adding more vibration force than required can affect the structure, compact some materials or produce an inefficient result. A considered silo vibration system applies the right vibration pattern in an appropriate position.

Electric hopper vibrators

Electric Models


Electric silo vibrators suit many fixed installations with a suitable power supply. Force can be adjusted on applicable models, and control options can coordinate vibration with the discharge or production process. Single phase, three phase and other configurations are available within our industrial electric vibrator range.

Pneumatic hopper vibrator

Pneumatic Models


Pneumatic silo vibrators use compressed air and are available with different operating characteristics. Rotary models produce vibration through rotating internal components, while piston models create linear movement. Explore our pneumatic linear vibrators when the application requires linear vibration or controlled impact.

Mounting and Control Matters

Performance depends on how vibration enters and travels through the structure. Silo wall construction, stiffeners, outlet geometry and equipment location all influence the result. Appropriate mounting helps distribute vibration while protecting the silo and vibrator.



Our team can advise on mounting silo vibrators, industrial vibrator mounting options, control methods and operating cycles. Final installation requirements should be assessed against the silo design and site safety procedures.

Discuss Your Hopper Flow Problem

Send us details of the silo, stored material, discharge problem and available power or compressed air. Vibration Systems can review the application and recommend suitable silo vibrators, mounting and controls. Call 1800 300 877 or email sales@vibrationsystems.com.au.

FAQs About Silo Vibrators in Australia

  • What does a silo vibrator do?

    A silo vibrator transfers vibration into the silo structure to encourage bulk material movement. It can help reduce bridging, rat holing, sticking and inconsistent discharge when correctly selected and installed.


  • Should I use an electric or pneumatic silo vibrator?

    The choice depends on available services, required vibration characteristics, duty cycle, environment and the stored material. Vibration Systems can compare suitable electric and pneumatic options for the application.


  • Where should the equipment be mounted?

    Mounting position depends on the location of the flow problem, silo construction and discharge design. The structure must be assessed before mounting details are confirmed.


  • Can a silo vibrator stop material bridging?

    Industrial vibrators can help address bridging when vibration is appropriate for the material and structure. The underlying flow behaviour should be assessed so the equipment does not compact the product or transfer force into an unsuitable area.


  • Can you help select a complete silo vibration system?

    Yes. Provide the silo dimensions, construction, stored material, operating conditions and details of the flow problem. Our team can recommend suitable equipment, mounting and control options.
