Silo Filling Systems

High Filling Capacity. Minimum Dust Emissions

Reliable silo operation begins with safe, controlled and efficient filling. VOLDE engineers silo filling systems tailored to specific bulk material characteristics, required capacities and operating conditions. Our solutions are designed to ensure high transfer rates, effective dust control and energy-efficient operation while providing reliable integration with storage silos and upstream bulk material handling systems.

| Silo Filling by Dense Phase Conveying

Low Conveying Velocity. Reduced Wear. Efficient Silo Filling

Dense phase pneumatic conveying enables the gentle and reliable transfer of abrasive, fragile and high bulk-density materials over long distances. Using the DENSPLUS pressure vessel, bulk solids are conveyed through a fully enclosed pipeline at low conveying velocities and with minimal air consumption, reducing product degradation, pipeline wear and dust emissions.

• Minimal product degradation and material segregation
• Low conveying air consumption
• Reduced pipeline wear through low conveying velocities
• Enclosed, dust-tight material transfer
• Reliable conveying over long distances and complex routes

| Silo Filling by Dilute Phase Pneumatic Conveying

Continuous Conveying. Efficient and Dust Controlled Silo Filling.

Dilute phase pneumatic conveying provides a cost-effective solution for continuous silo filling over short to medium distances. A positive-pressure blower generates the conveying air required to transfer bulk materials through the pipeline, while a silo vent filter separates displaced air and controls dust emissions during filling.

• Positive-pressure blower conveying system
• Cost-effective and continuous material transfer
• Simple operation and low maintenance requirements
• Compact and flexible system configuration
• Effective dust control through silo vent filtration

| Silo Filling from Bulk Tankers

High Capacity, Dust Controlled Tanker Unloading

Bulk materials delivered by road tanker are pneumatically transferred directly into the storage silo using the tanker’s onboard blower or compressor. Silo vent filtration, level monitoring and overfill protection ensure safe and dust-controlled filling, while dedicated filling connections provide reliable coupling between the tanker and silo.

• High capacity pneumatic tanker unloading
• Safe and dust controlled silo filling
• Dedicated filling connections and hose couplings
• Level monitoring and overfill protection
• Interlocking between tanker unloading and silo safety systems
