Stockpile Loading Bellows

Stockpile loading bellows 3d bulk solid discharging
Stockpile loading bellows are used for dust free discharging of powdered and granular bulk solids to stockpiles. Free flowing dry bulk solids in powder and granule form are easily transferred from silos, hoppers, containers, screw feeder to stockpile basement. Built in flexible dust skirt prevents the dust emission outside of the loading region.

Operation of Stockpile Loading Bellows

At the beginning of stockcpile loading, bellow is lowered towards the ground and stops at the bottom. Flexible dust skirt located at the bottom of bellow keeps the dust content inside the loading area. During material discharge, bellow dust skirt provides a closed containment for dust. Dust collection unit vacuums any fugitive dust in the region and prevents dust emission to the surrounding. Collected dust is then sent back to the product stream continuously and material waste is prevented 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 with winch system and it maintains a space to let the material flow rapidly. After stockpile 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.
