Pneumatic Big Bag Unloading & Silo Filling Systems

Efficient, Clean, and Reliable Bulk Material Handling

The SYORITEC pneumatic Big Bag unloading and silo filling system provides a fast, dust-free, and fully enclosed solution for transferring powdered and granular raw materials from big bags into one or multiple silos.
Designed for industrial environments that require hygiene, precision, and continuous operation, this system ensures safe and contamination-free handling of materials such as cement, calcite, lime, gypsum, starch, bentonite, talc, PVC, and many others.

How the System Works

Bulk materials discharged from the Big Bag are fed into the pipeline through a rotary valve or airlock. Depending on the application, the material is transported to the silo using:

• Positive-Pressure Conveying (Dilute Phase / Dense Phase)

Compressed air pushes the product through the pipeline horizontally or vertically.
Material diverter valves enable feeding multiple silos, while jet pulse filters separate the product from the conveying air at the silo top.

• Vacuum Conveying (Negative Pressure)

Ideal for heat-sensitive or explosive materials.
The blower creates suction along the pipeline, drawing the material into a jet cyclone where it is separated and then discharged into the silo through a rotary feeder.

Both methods operate automatically through level sensors, pressure valves, and a control panel that ensures stable and continuous system performance.

System Components

A complete SYORITEC pneumatic unloading and filling system typically includes:

• Big Bag unloading station

• Blower or compressor unit

• Rotary valve / airlock feeder

• Pipeline and fittings

• Diverter valves

• Jet pulse filter or jet cyclone

• Silo level sensors

• Silo pressure safety valve

• Discharge equipment (slide gate, butterfly valve, vibration cone)

Key Advantages

• Fully enclosed conveying with zero dust emissions

• High conveying capacities for long horizontal and vertical distances

• Low maintenance thanks to minimal moving parts

• Gentle material handling compared to mechanical conveying

• Ability to feed multiple silos from a single unloading point

• Hygienic and contamination-free transfer ideal for food and chemical products

• Reliable operation even with difficult-flow materials

Where the System Is Used

SYORITEC pneumatic Big Bag unloading and silo filling systems are widely used in industries such as:
Cement – Construction chemicals – Ready-mix concrete – Plastics – Minerals – Food – Pharmaceuticals – Energy – Ceramics – Agriculture – Seed processing – Chemicals – Glass – Paper – Animal feed – Wastewater treatment, and more.

They are suitable for transferring materials from big bags into storage silos, mixers, reactors, feeding hoppers, and process tanks.
