BUNKER DISCHARGE MACHINE  Functional & Structural Description

The BDM is a device for discharging difficult to handle bulk materials from bunkers, hoppers, bins, silos, stockpiles and dome type storages.  The arms of the Bunker Discharge machine rotate and reclaim bulk material from the bunker shelf onto a conveying system.  The Bunker Discharge Machine (1) travels automatically and self-propels through a tunnel (2). The material is conveyed along the arms by the rotation of the discharge wheel (3) and discharged along the bunker shelf (4) onto a gathering conveyor (5). WTW’s Bunker Discharge Machine is a device for discharging difficult to handle bulk materials from bunkers, hoppers, bins, silos, stockpiles and dome type storages. The arms of the Bunker Discharge machine rotate and reclaim bulk material from the bunker shelf onto a conveying system.

Sizes from Ø 2.0 m to Ø 4.0 m Discharge Rates from 10 to 3,500 t/h

Bunker Discharge Machines are available in a variety of designs and configurations to meet many applications

• Reclaiming from both bunker shelves 

• Travel and discharge drives in one reducer 

• Handles large capacities at low discharge wheel speed 

The BDM’s discharge wheel has six logarithmic shaped discharge arms which guarantee consistent feeding of any bulk material. The arms are bolted to a hub which is connected by a shrink disk to the output shaft of the reducer. Discharge arms are lined with wear resistant liner plates designed to increase the life of each discharge arm.

The bottom of each discharge arm contains a scraper section. These scrapers prevent material compaction and buildup on the shelf floor that could eventually lift the BDM off its travel rails.
