Operation of Open Truck Loading Bellows
At the beginning of open truck loading, bellow is lowered towards the flatbed of truck and stops at the bottom. Flexible dust skirt located at the bottom side of bellow keeps the dust content inside the loading region. During material discharge, it provides a closed containment for dust. Dust collection system collects any fugitive dust in the region and prevents dust emission to surrounding. Collected dust is sent back to the product stream continuously and no material is wasted during loading. Built in level sensors monitor the product level below the loading bellow dust skirt. When the material level increases, bellow is retracted upwards automatically and it maintains a space to let the material flow rapidly. After truck loading is finished, product discharge valve above the loading bellow is closed. System waits for few seconds to complete product flow and to collect remaining dust by dust collector. Loading bellow automatically retracts to the top position afterwards.
Advantages– Dust free loading – Dust free working region, prevention of dust pollution, ensure plant and environmental safety. – Suitable for different bulk solids conveying and storage systems – Loading is possible from different equipment like silo, hopper, screw feeder, conveyors etc. – Extensive range of models are available for wide range of needs – Built in flexible dust skirt to prevent dust emission outside of the loading region. – No spillage and no product waste – Materials with high temperatures up to 300 C can be loaded. – Food grade loading bellows are available – Simple operation – Easy maintenance
