Market-leading technology for handling dry bulk cement

Bruks Siwertell revolutionized the cement market when it introduced the Siwertell ship unloader in 1975, bringing with it levels of efficiency and environmental protection that had not been seen before.

We offer a full range of terminal systems for handling dry bulk cement, including loaders, unloaders, road-mobile unloaders, conveyors, storage and reclaiming systems and turn-key projects.

Highest capacity worldwide

A 1,500t/h Siwertell cement unloader in Houston, Texas, USA, offers the highest capacity on the market for its kind.

The Siwertell ship unloader is part of Houston Cement Company’s terminal, which includes cement unloading and storage silos of up to 100,000 metric tons in total. With low costs for maintenance and power consumption, this heavy-duty unloader is exceptionally suitable for the terminal’s high yearly throughput.



Tailored systems for dry bulk cement

For any dry bulk cement operation, we have the know-how when it comes to tailoring solutions to meet each customer’s needs. In recent years, we have delivered the market’s highest unloading capacities in dry bulk cement handling.

Outstanding product capacity

Siwertell ship unloaders and loaders have set cement industry standards for decades, offering some of the highest unloading and loading capacities available on the market. Our cement unloaders have rated capacities of up to 1,500t/h, reflecting the use of larger vessels for cement transportation.


As for loaders, Bruks Siwertell has delivered systems with loading capacities as high as 4,000t/h for ships up to Panamax size. However, we tailor our solutions to suit each customer’s needs, so higher unloading and loading capacities can be achieved if required. Ideally suited to conveying this material is our innovative air-supported conveyor range, which includes the Bruks Tubulator TM and The Belt Conveyor TM .

Loader upgrade increases capacity and improves environmental protection

Adelaide Brighton Cement, in Australia, needed a new conveying system to reduce dust emissions and increase cement loading capacity. Its order for a Siwertell enclosed horizontal screw-conveying system replaced a belt conveyor arm on its existing cement and clinker loading facility.

Demonstrating the flexibility of Bruks Siwertell’s engineering capabilities, the project called for a new screw conveyor loading arm and upper turret section to integrate with both the existing slewing ring tower support and the existing winch system. It now serves the operators with a maximum rated capacity of 900t/h, but runs at a service capacity of 600t/h for clinker.

Changing market demands

Increasing demand has pushed cement shipping to larger volumes. Operators are switching to bigger vessels and require higher handling rates. The common terminal configuration until the late 1990s was geared to unload Handymax-sized ships at rates of 800t/h. Today’s volumes require many terminals to accommodate Panamax tonnage and offer quicker turnarounds by raising loading and unloading rates. We have the cement handling capabilities to meet these rising demands.
