Open Environment Filling Bellows B Series
What is Open-Air Loading Spout B Series?
The Open-Air Loading Spout B Series is designed for the safe and dust-free loading of silo trucks, wagons, and closed vehicles. It transfers powders, granules, and bulk materials from storage and conveying units into silo trucks while preventing dust emissions. The integrated dust collection filter eliminates particles during loading, protecting the environment and preventing material loss. In different industries, it is also known as a telescopic chute or silo loading spout.


Working Principle
The operator activates the drive system to position the loading spout onto the silo truck inlet. Once the inlet valve or loading device is opened, the product flow begins. Dust particles generated during the process are captured by the built-in dust filter. A level sensor at the outlet detects the material level and stops the feed automatically. After the final dust is removed, the spout retracts automatically, completing the process safely.
Advantages and Applications
The B Series Open-Air Loading Spout features an automatic retraction system, position sensors, and a rotation counter for reliable operation. Its dust-free loading technology ensures safe, efficient, and environmentally friendly performance. Widely used in cement, food, chemical, plastic, and mining industries, it is an ideal solution for modern bulk handling facilities.
