US: The Alabama Department of Environmental Management (ADEM) has ordered Holcim US to pay a US$100,000 fine for alleged fugitive dust emissions from its Theodore cement plant in Mobile. Between February and August 2022, witnesses reported multiple dust plumes sighted above the plant, which is situated on the Theodore canal. AL.Com News has reported that, while neither admitting or denying the contentions, Holcim US said that it has taken actions affecting its raw materials unloading processes to ensure compliance.

Plant manager Clay Copeland said “We have worked closely with the ADEM to address concerns raised earlier this year."

Sri Lanka: Lanwa Sanstha Cement says that it will commission its 2.8Mt/yr Hambantota grinding plant in Mirijjawila Export Processing Zone in early March 2022. The project had previously been scheduled for delivery in January 2022. Lanka Business Online News has reported that China Merchant Ports subsidiary Hambantota International Port Group agreed to supply a 2.4km conveyor belt and two ship unloaders in November 2021. After commissioning the grinding plant, Lanwa Sanstha Cement will proceed with Phase 2 of its work to increase the facility’s capacity to 4Mt/yr.

Kuwait: Bruks Siwertell has received an order from Kuwait Portland Cement for a ST 490-M type ship unloader. The rail-mounted unit will handle various cement types and deliver a continuous material handling capacity of 800t/hr, discharging vessels up 50,000dwt. It will be installed on an existing jetty next to the customer’s older ST 490-F type rail-mounted Siwertell unloader. Delivery to the port is planned for mid-2023. A notable feature of the order is the unit’s ability to withstand high ambient temperatures of up to 55°C.

US: Sweden-based Bruks Siwertell has commissioned a 1500t/hr rail-mounted Siwertell ST 640-M screw-type ship unloader for an undisclosed cement customer at Houston, Texas. The unloader will serve ocean-going vessels on the Buffalo Bayou watercourse. The producer is transitioning from bagged to bulk dispatch. Contract manager Per Wahlström said that the company was also looking to expand its US operations.

The supplier says that the new unloader offers continuous dust-free cement handling with a peak capacity of 1650t/hr, discharging vessels up to 80,000dwt with zero spillage. Bruks Siwertell also supplied192m-long jetty conveyors with a belt width of 1.6m. Wahlström said “The Siwertell unloader was an ideal choice for this terminal. It was light enough to minimise costs, yet deliver the through-ship capacity required.”

US: Bruks Siwertell is targeting its port-mobile unloader at the cement, alumina, and soya meal sectors after initially launching it to serve grain handling. It says the product has shown numerous advantages for use in cement handling and due to its enclosed design the unloader offers “no spillage and close-to-zero dust emissions.” It is available in 400t/hr or 600t/hr models and comes with a +/-30° articulating conveyor arm.

Director of mobile unloaders Jörgen Ojeda said, “For operators looking for a port-based system retaining similar flexibility during operation, but needing to discharge much larger vessels at a higher capacity, then our new port-mobile unloaders are a fantastic, extremely cost-effective option.” He added that screw-conveyor unloaders have the benefit over pneumatic discharge systems that they produce no fines, thanks to their “steady conveying velocity, with no particle collisions or crushing forces.”

Singapore: Jurong Port has ordered three Siwertell ship unloaders from Bruks Siwertell to handle cement imports. The port’s cement terminal already has three Siwertell ship unloaders that have been used for over 20 years. Two of these will be replaced as part of the upgrade project.

The three new ST 490-M screw-type rail-travelling unloaders will each discharge cement, fly ash and cement slag from vessels up to 50,000dwt at a continuous rated capacity of 800t/hr. Two of the new unloaders are scheduled for delivery in May 2022 and the third by the end of 2022. All will be fully assembled prior to delivery and transported by heavy-lift ship. Final commissioning and performance tests will be carried out in Jurong Port.

Belarus: Krichevcementnoshifer exported US$2.47m-worth of cement in the first quarter of 2020, up by 41% year-on-year from US$1.75m-worth in the corresponding period of 2019. Belta News has reported that the company, whose 0.6Mt/yr integrated plant at Krichev, Mogilev region serves the eastern Belarusian and Russian markets, made total sales of US$15.4m, up by 22% year-on-year from US$12.6m. Krichevcementnoshifer CEO Vladimir Korchevsky said, “We consistently ship 5000t of cement to consumers every day. April 2020 saw shipments reach 6000t/day. We can conclude that, despite the current difficulties associated with the coronavirus pandemic, the demand for our products has not decreased.”

In April 2020 Krichevcementnoshifer completed construction of an elevated track for the unloading of bulk materials from railway cars, reducing unloading time.

US: Bruks Siwertell, the producer and installer of conveying and storage systems for cement and other dry bulk materials, has delivered a fully-assembled Siwertell ST 640-M, the screw-type ship unloader to South Texas Cement’s Corpus Christi port terminal. The suppliers have announced that they await clearance from South Texas Cement and GCCM Holdings to commence testing and commissioning of the turnkey installation, which the latter ordered in September 2018. Bruks Siwertell rates the cement handling capacity of unloaders of the ST 640-M type at 1500t/hr.

Australia: Southern Cross Cement, a joint venture between Brickworks, Neilsen Group and Neumann Group, is planning to open a 0.2Mt/yr terminal by October 2019. The US$60m unit will import cement from south east Asia, according to the CourierMail newspaper. It is anticipated to supply 10% of Queensland market. A 12,000t/day mechanical ship unloader will be installed at the site.

Germany/China: Baltrader Capital has ordered the construction of two cement carriers from China’s Fujian Southeast Shipbuilding, who will deliver the new vessels from end of 2020. The ships will be intended for the European shortsea trade. Following the completion of the order, the Baltrader fleet will comprise 12 cement carriers with pneumatic self-discharging systems.

Each of the sister vessels, CemCoaster and CemClipper, measures 98m in length, 15.6m in width and carries 4650t at 6m draft. They will be equipped with a MaK main engine, allowing a future conversion into dual fuel operation. The ships will then be optionally run on liquid natural gas (LNG) or on marine gasoil.

The ships have been planned and designed in Germany by SDC Ship Design & Consult in cooperation with the project engineering department of the BRISE-Group. Dutch producer Van Aalst Marine & Offshore will supply the automatic self-discharging system, powered alternatively by the main engine’s shaft generator or the auxiliary generators. It can be used for the transportation of loose cement, ground granulated blast-furnace slag and fly-ash. It will have a loading capacity of 500t/hr and unloading capacity of 250t/hr. Additionally, these iceclass 1B ships are equipped with a ballast water treatment system (BWTS).
