Hoppers & silos
Hopper / silo
Hoppers and silos store bulk solids between process stages. Cone angle, volume and plate thickness follow flow behaviour; discharge is via slide gate, vibratory discharger or rotary valve.

Operating principle
Steel vessels are designed for throughput, angle of repose and discharge method. Cone angle and optional wear linings keep flow moving. Discharge sits at the low point: a slide gate, vibratory discharger or rotary valve meters into the next stage.
Where this machine is used
Intermediate storage in crushing-screening plants, cement, fertiliser, food and chemicals – for aggregates, calcite, grain and powders.

Frequently asked sizing questions
What information does UnionBridge need for a hopper or silo?
Key data includes bulk material, bulk density, moisture, particle size, flow behaviour, required working volume, inlet and discharge rate, required buffer time, installation location and temperature. Flow testing may be useful for difficult materials.
How are bridging and ratholing addressed?
Hopper geometry, outlet size, surfaces, lining and possible flow aids are selected from the actual flow behaviour. Vibration or agitators are not universal remedies and are used only when justified by the material and process.
Which interfaces must be clarified before quotation?
The filling and discharge points, connection dimensions, support structure and loads, level measurement, dust extraction, maintenance access and explosion and occupational-safety requirements must be clarified. Supply scope and customer responsibilities are then clearly separated in the quotation.
