Telescopic Chute for Silo

- Working Principle: How Our Silo Telescopic Chute Operates
- Technical Specifications
- Key Features of Darko Telescopic Loading Spouts
- Versatile Silo Discharge Solutions
- Positioning
After vehicle parking under the silo, the retractable loading spout is lowered by heavy-duty electric winch until the discharge cone fits tightly on the vehicle inlet.
- Gravity Discharge
Open the silo discharge valve, bulk material flows down by gravity through wear-resistant inner cones of the telescopic chute, avoiding material segregation and splashing.
- Dust Extraction
When filling starts, displaced dust-laden air is collected through dual-wall loading bellows. Dust is guided to dust collector or returned to the silo for zero leakage.
- Automatic Retraction
Built-in tilt and rotary level sensors detect material height in real time. The telescopic loading spout retracts automatically with rising material level until loading is completed.
