Silo Discharge Systems

Silo Discharge Equipment for Reliable Material Flow Preventing Bridging. Ensuring Consistent Discharge.

Reliable silo operation depends not only on safe filling, but also on controlled and uninterrupted material discharge. VOLDE engineers silo discharge solutions according to bulk material characteristics, flow behavior and downstream process requirements. From cohesive and difficult-to-flow powders prone to bridging or ratholing to free-flowing granules, each system is configured to ensure consistent mass flow, minimize material retention and provide reliable feeding to downstream process equipment.

Bin Activator

Mounted beneath the silo outlet, the SILOCONE Bin Activator uses a suspended, vibratory cone to promote reliable flow of cohesive, compacting and difficult-to-handle bulk materials. Controlled vibration helps prevent bridging and ratholing, ensuring consistent material discharge to downstream process equipment.

Advantages:

Prevents bridging and material compaction
Promotes consistent and reliable bulk material flow
Reduces the risk of blockages and flow interruptions
Low energy consumption and quiet operation
Effective flow activation through controlled vibration

Fluidizing Cone

Silo fluidizers use low-pressure air to aerate the material along the silo cone, reducing friction and promoting reliable discharge of fine powders and other difficult-to-flow bulk solids. Specially designed aeration pads or fabric diffusers provide localized flow assistance without mechanical agitation.

Advantages:

Gentle, controlled material discharge
Effective flow assistance with low-pressure air
No moving parts and low maintenance requirements
Suitable for food and chemical applications with appropriate material selection
Compact, modular design for easy installation

FLOW SUPPORT

Other Equipment

Pneumatic Impactor

Delivers controlled, intermittent impact pulses to the silo wall to dislodge adhered or compacted material. An effective flow-aid solution for cohesive and difficult-to-flow bulk solids.

Vibrating Aerator

Combines low-pressure aeration with localized vibration at the silo cone to promote material flow and reduce bridging, compaction and material build-up

External Vibrator

An electromechanical vibration unit mounted on the silo cone or wall to promote discharge of cohesive and difficult-to-flow bulk materials and reduce material build-up.

CONTROL & INTEGRATION

Compatibility with Automation

PLC / SCADA Integration

Silo discharge systems can be fully integrated with PLC and SCADA platforms for automated control, remote monitoring and coordinated operation with downstream process equipment

Automatic Discharge Control

Integrated level sensors and process signals enable demand-based activation of silo discharge equipment, ensuring continuous material supply while minimizing manual intervention.

ATEX-Compliant Systems

For potentially explosive dust atmospheres, silo discharge systems can be configured with ATEX-certified components and appropriate protection measures for safe and reliable operation.

Process Connections & Discharge Valves

Project-specific outlet flanges and discharge valves ensure seamless mechanical integration with downstream feeding, dosing and conveying equipment while providing reliable material flow control.
