Discharge to Silo

Discharging bulk bags directly into silos is a common solution for industrial processing operations where materials need to be stored temporarily before entering the next phase of processing. This configuration is widely used in industries such as food processing, chemicals, plastics, and construction materials, where controlled flow, minimal material loss, and dust-free operation are essential.

How the System Operates

  • Bag Positioning:
    The bulk bag is lifted onto a discharge frame equipped with bag support hooks or a lifting frame.
  • Flow Activation:
    Once the big bag outlet is connected to the silo inlet, flow is activated either by gravity or aided by flow-assist devices (such as big bag massagers, vibrators, or flow cones).
  • Controlled Discharge:
    A valve or dosing system (such as rotary valve or screw feeder) is installed between the big bag and silo to regulate the flow rate.
  • Dust Management:
    Integrated dust collection ports ensure that material transfer occurs in a sealed environment, reducing airborne contamination

Key Components
  • Support Frame: Rigid frame with hoist or forklift access for easy bag loading.
  • Discharge Spout Interface: Includes a sealed connection to the silo inlet to prevent leakage.
  • Flow Aid Devices: Massaging system or vibratory devices help to achieve consistent material flow.
  • Dust Collection System: Filter systems or dust extractors maintain a clean environment.
  • Level Sensors: Installed in silos to measure the amount of material inside and avoid overfilling.
Key Advantages
  • Continuous Processing: Allows uninterrupted feeding to downstream processes.
  • Dust-Free Operation: Enclosed design minimizes environmental contamination.
  • Efficient Storage: Helps manage material flow between processing stages.
  • Versatile Integration: Can be connected to silos of various shapes and sizes.
Industry Applications
  • Food Industry: Food products such as flour or starch is discharged into silos equipped with hygienic linings and stainless steel contact surfaces. This ensures compliance with food safety standards and prevents product contamination.
  • Chemical Industry: Fine powders like pigments or resins are discharged into sealed silos using ATEX-compliant equipment. This setup ensures safe handling of potentially explosive or hazardous materials.
  • Construction Industry: Cement, gypsum, or lime is transferred from big bags into buffer silos that feed mixing equipment. The silos help regulate material flow and maintain a continuous supply for downstream processing.
  • Plastics Industry: Plastic pellets or granules are discharged into silos designed for dust-free and contamination-free storage. These silos support consistent material feeding into extrusion or molding lines.
