Common Silo Problems We Solve
Uncontrolled conditions lead to downtime, safety risks, and material loss.
Bridging
Material forms a stable arch above the outlet, preventing discharge and stopping material flow.
Ratholing
Material flows through a narrow channel while large volumes remain stuck along the silo walls.
Silo fire & ATEX - Exposure
Accumulated dust, combustible materials and restricted airflow can increase fire and ATEX-related hazards.
Material Build-up
Layers of material accumulate on internal surfaces, reducing capacity and increasing blockage risk.
Compaction
Stored material becomes densely packed over time, making discharge difficult and restricting flow.
Flow interruptions
Irregular or inconsistent material movement disrupts production and can lead to unplanned downtime.
Why Silo Blockages Happen
💧 Moisture
Changes in humidity or water ingress can cause material to stick, harden or compact inside the silo. Over time, this can lead to bridging, build-up and restricted flow.
Common result: Increased blockage risk and production downtime.
Typical symptoms: Bridging, compaction, reduced discharge rate.
Common materials affected: Cement, fly ash, lime, gypsum.
⚙️ Material Characteristics
Particle size, density, cohesiveness and flowability directly influence how material behaves during storage and discharge. Poor-flowing materials are more likely to bridge or form ratholes.
Common result: Inconsistent discharge and recurring flow interruptions.
Typical symptoms: Ratholing, segregation, erratic material flow.
Common materials affected: Cement, biomass, fertilizer, alumina.
🌡️ Storage Conditions
Temperature fluctuations, prolonged storage periods and uneven filling patterns can affect material stability and flow performance.
Common result: Reduced flowability and increased blockage frequency.
Typical symptoms: Material hardening, compaction, inconsistent discharge.
Common materials affected: Fly ash, biomass, coal, grain.
📐 Poor Flow Design
Incorrect hopper angles, outlet dimensions or silo geometry can prevent material from flowing efficiently through the discharge point.
Common result: Persistent flow restrictions and repeated blockages.
Typical symptoms: Bridging, ratholing, dead zones.
Common materials affected: All bulk solids, particularly cohesive powders.
🧱 Long-Term Build-up
Material deposits gradually accumulate on silo walls and internal structures, reducing effective storage volume and restricting flow paths.
Common result: Reduced capacity and increased maintenance requirements.
Typical symptoms: Build-up, narrowing flow channels, unexpected blockages.
Common materials affected: Cement, clinker dust, lime, fly ash.
🔥 Silo Fire & ATEX Exposure
Accumulated dust, combustible materials and restricted airflow can create conditions that increase the risk of fire or dust explosions inside the silo.
Common result: Safety hazards, equipment damage and operational shutdowns.
Typical symptoms: Dust accumulation, hot spots, smouldering material.
Common materials affected: Biomass, coal, grain, wood pellets, combustible powders.
