Two Siwertell road-mobile unloaders for US cement handler

(Posted on 11/11/21)

Bruks Siwertell will deliver two new Siwertell road-mobile ship unloaders for dust-free cement handling operations in North America. Destined for an undisclosed owner, these new 5000 S units will join the company’s other existing Siwertell technology. They will provide a flexible, environmentally friendly solution for unloading cement at planned future sites, and will enable better access to barges and port facilities.

“Siwertell ship unloaders are located across the world and have decades of proven, dedicated service,” says Pedro Alfaro, Project Development Engineer, Bruks Siwertell. “Road-mobile units are extremely flexible in their ability to serve operators at multiple ports, and are robust and easy to operate. In fact, a single operative can unfold a road-mobile unloader in less than an hour, and then clear the quay in equal time once finished.”

As with larger unloaders, Siwertell road-mobile units use screw conveyors that are fully enclosed, with a dust mitigation system, which limits any fugitive dust to an absolute minimum. They also ensure than no dry bulk material is lost through spillage. Road-mobile unloaders have a double-bellows discharge arrangement and can transfer material to waiting trucks or any other receiving system.

Both unloaders will have a rated cement handling capacity of 300t/h for vessels up to 5,000 dwt. They are the latest iteration of the 5000 S, and will have electric as opposed to diesel-drives, further reducing environmental impact. Other advanced features include technology for diagnostics and trouble-shooting.

The first unit will be delivered to the US Midwest in summer 2022, with commissioning scheduled for winter 2022, and the second unit, destined for the Southeast region, will be delivered in summer 2022, with commissioning by spring 2023.
