Open Truck Loading Bellows


Open Truck Loading Bellows Bulk Solids Handling Truck Loading
Open truck loading bellows are used for dust free loading of powdered and granular bulk solids into flatbed open trucks. Free flowing dry bulk solids in powder and granule form are easily transferred from silos, hoppers, containers, screw feeder to open trucks. Built in flexible dust skirt prevents the dust emission outside of the loading region.





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.
