Siwertell ship unloader meets Quezon’s doubled power demands

A new Siwertell ST 790 D-type ship unloader now serves Quezon Power Ltd Co’s newly built coal-fired San Buenaventura power plant in Mauban, the Philippines. The 500 MW facility is the country’s first supercritical power station and is located next to an existing Quezon power plant. long-term value from high jetty utilization rates, reliability and the long service life of wear parts.

Since coming online, the operator’s energy output has doubled, requiring an equivalent doubling of coal intake to around three million metric tons a year. These needs are now met with two rail-traveling Siwertell ST 790 D-type unloaders, which share the same jetty, rails and belt conveyors.

The first Siwertell ship unloader was delivered in 1998 and has been in operation for almost 25 years. The latest unit was delivered, fully assembled via heavy-lift ship, to the site in early 2022. Both unloaders have a continuous rated capacity of 1,400t/h and are able to discharge vessels up to Panamax size.

“The jetty has significant weight restrictions, making the Siwertell unloader a stand-out choice for this installation,” says Per Wahlström, Project Manager, Bruks Siwertell. “Its high capacity to weight ratio was likely to have made it the only equipment with sufficient capabilities that could be installed.” “Quezon knows that our machines deliver excellent operational and environmental credentials,” notes Wahlström. “The company’s satisfaction with its existing unloader certainly played a part in it ordering a second one.”

Environmental protection is also a major priority for Quezon, and any coal spillage is not permitted. Siwertell screw-type ship unloaders are one of most efficient and environment-friendly types of unloaders on the market. They deliver totally enclosed dry bulk material handling, eliminating spillage and dust emissions, and also ensure

Together, two Siwertell unloaders handle nearly three kilotons of coal per hour for Quezon

Road-mobile ship unloader ordered for dust-free cement handling in Sweden

Later this year, Swecem AB, a subsidiary of Peab Group’s Swerock, will take delivery of its Siwertell 10 000 S next-generation road-mobile ship unloader. Ordered to secure environment-friendly, dust-free material handling in the port of Helsingborg, Sweden, it will deliver a continuous cement unloading capacity of 300t/h, discharging vessels up to around 10,000 dwt.

“Environmental protection is a key consideration for Swecem’s operations and it adheres to very strict Swecem will meet increasing environmental demands with its new standards,” explains Jörgen Ojeda, Sales Director Siwertell unloader Mobile Unloaders, Bruks Siwertell. “With this in mind, Swecem was looking for a ship unloading solution that sustainable steps,” Ojeda continues. “Sweden has a could deliver continuously high through-ship capacities, mounting legislative drive to reduce the environmental but at the same time, ensure enclosed dry bulk material impact of the country’s cement industry. However, the handling to minimize any environmental impact. same industry has to maintain, and even exceed, current ship unloading capabilities to keep up with growth, posing “This is also an important order because it is part of a a potential future gap in supply and demand. Our systems growing picture that will see all operators taking more can, and will be, part of this positive change.”

Bruks waste handling system boosts sustainability at PCA mill

A new material waste handling system will soon be operational for Packaging Corporation of America (PCA). The receiving hopper, screw conveyors, and a conventional idler belt conveyor will handle rejects from old corrugated cardboard (OCC) to fuel boilers for power production at the company’s Jackson, southwest Alabama, US, containerboard mill.

“OCC rejects handling systems help operators convert waste into valuable energy,” says Pedro Alfaro, Project Development Engineer, Bruks Siwertell. “They are a good sustainability step and also deliver significant economic advantages, enabling operators to offset substantial energy demands.” PCA is the third largest producer of containerboard products and the third largest producer of uncoated freesheet paper in North America. Equipment from

Bruks Siwertell is a feature at several of its eight mills and 90 corrugated products plants.

To meet a growing strong demand for US domestic packaging, the company made the decision earlier this year to convert production machinery (No 3) from paper to linerboard at the Jackson mill. PCA plans to convert the 365,000 ton/year paper machine to a 700,000 ton/year high-performance, virgin kraft linerboard machine in a phased development over the next three years. As part of these changes, it needed robust, proven equipment that was capable of handling coarser OCC rejects at high efficiencies, and a system that could meter the flow of the waste material as well.

The Bruks equipment has a combined OCC reject handling capacity of 5.4 to 10.9 metric tons/hour (6-12 short tons/hour). “Our design delivers the reliability and robustness that the mill requires, and is cost-competitive,” adds Alfaro.

Doubled cement handling demand in Kuwait port will be met by Siwertell ship unloaders

A high-capacity ship unloader order is underway for returning customer, Kuwait Portland Cement Co. The ST 490-M Siwertell unit, equipped with a new side tilt motion for enhanced through-ship efficiency, will join another cement handling Siwertell ship unloader in Shuaiba Port, Kuwait City, Kuwait, which has been operating for over two decades.

“Kuwait Portland Cement has benefited from 20 years of experience using our Siwertell screw-type technology,” says Peter Göransson, Sales Manager, Bruks Siwertell. “It knows what our unloaders deliver; time and again the technology has proven its capabilities, demonstrating reliability, efficiency, and environmental protection in terms of emissions and noise. the chance of airborne emissions from avalanches in the cargo hold. The side tilt function adds to this capability,” Göransson notes.

Planned for delivery to the port in mid-2023, the railmounted unit will handle various cement types and deliver a continuous material handling capacity of 800t/h, discharging vessels up to 50,000 dwt. It will be installed on an existing jetty next to the operator’s older ST 490-F, rail-mounted Siwertell unloader.

“In fact, the main reason why the operator returned for a second unit is the outstanding operational performance of its original delivery,” continues Göransson. “Our ongoing service support, along with Bruks Siwertell’s throughlife commitment to maintenance and spare parts were other major deciding factors.”

The new unloader will deliver even higher levels of performance and through-ship efficiency to Kuwait Portland Cement. “It features a new side tilt motion, which offers an enhanced reach into the corners of the cargo hold as well as under the hatch coamings,” he adds. “As a result, less material is left for the clean-up phase, which reduces vessel turnaround times, raising the utilization rate of the jetty and therefore profitability. Like its predecessor, the new unloader is also designed to operate in Kuwait’s extreme climate. To accommodate predicted temperature rises in the region, the latest unit can withstand ambient summertime temperatures of up to 55 degrees Celsius.

“Also, all Siwertell unloaders offer a layerby-layer unloading process, which minimizes
