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.
Advantages– Dust free loading – Dust free working region, prevention of dust pollution, ensure port 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. – Built in flexible dust skirt to prevent dust emission outside of the loading region. – Extensive range of models are available for wide range of needs – No spillage and no product waste – Food grade loading bellows are available – Simple operation – Easy maintenance
Cement, fly ash, mining minerals, calcium carbonate, pvc, plastic pellets, plastic powders, alumina, bentonite, bauxite, coal, cement clinker, gypsium, kaolin, limestone, marble powder, soda ash, quartz, urea, sodium sulphate, wheat, flour, animal feed, seed, corn, rice, sugar, salt and similar powdered and granular dry bulk solids.
Extensive range of loading bellows are available for wide range of applications. Open truck loading, bulk tanker filling, stockpile loading and bulk ship loading bellows provide dust free outloading of bulk materials for industrial applications.
Bulk solid transfer equipment are used to transfer powdered and granular materials to loading bellows. Bulk materials are discharged from silos, hoppers, production lines with these transfer and conveying equipment.
Loading bellows and bulk solid discharge systems can be provided with extensive range of optional components and accessories for different application needs. Proper selection of accessories is essential for efficient and dust-free loading.
