Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

US: Bulk materials handling specialist Conveyor Components has announced the launch of the Tripper Position Switch (TPS), a control unit consisting of two SP/DT micro switches rated for 20A at 120V, 240V or 480V. The unit indicates when the tripper of a shuttle conveyor is located on a multiple discharge point and will activate the dumper when signalled. Conveyor Components says that the device is housed in a “cast aluminium enclosure rated for NEMA 4 weather-proof or NEMA 7/9 explosion proof.”

Russia: Yakutcement has commissioned a crushed stone conveyor to circulate crushed stone of a 200 - 400mm fraction for secondary crushing at the 0.4Mt/yr Yakutcement plant in Mokhsogollokh. Yakutcement has said that the installation will save on the costs of a front-end loader and dump truck for conveying crushed stone to and from a temporary warehouse prior to secondary crushing.

Uzbekistan: Russia’s Eurocement has revealed that construction work underway at its 2.0Mt/yr integrated Akhangarancement cement plant in Tahskent region includes the installation of a second plant on the site, bringing its total capacity to 5.0Mt/yr. Trend News Agency has reported that suppliers have delivered 4500t of machinery to Akhangarancement, including a clinker refrigerator, clinker conveyor and heat exchanger as well as electrical equipment and building materials for a raw materials warehouse. Eurocement’s total investment in the project has amounted to US$200m.

Eurocement Group Holding International president Mikhail Skorohod said, “Taking into account the growing needs of the Uzbek market in building materials, Eurocement is committed to creation of a building materials cluster based around the Akhangarancement plant.” The company said that the upgraded 5.0Mt/yr plant would become operational in 2020.

Sweden: A failure on a conveyor belt between the kiln and a mill at the end of October 2019 has caused a ‘significant’ loss of production at Cementa’s Slite plant. The subsidiary of Germany’s HeidelbergCement says that a temporary solution is in place but that the unit’s capacity has been reduced. Repair work is expected to continue until the end of November 2019. The cement producer said that deliveries of its Basement product would be reduced while it looks for an external supplier to bolster supply.

Spain: FYM-HeidelbergCement has launches a new clinker conveyor at the Port of Malaga. The new Euro2.5m project started by loading 4800t of clinker onto a ship bound for Ireland. The conveyor will continue to be tested in August 2019 with 30,000DWT and 40,000DWT vessels. The enclosed conveyor has a load capacity of 650t/hr. the project also included setting up two storage areas in the Pescadería area of the city.

Turkey: Aslan Cement, part of Oyak Cement Group, has placed an order with Germany’s Aumund Fördertechnik for its Darıca plant in Kocaeli Province. The order is part of a project to increase the plant’s clinker production capacity to 6600t/day. The machines are due to be dispatched in September 2019 and commissioning is planned for the beginning of 2020. No value for the order has been disclosed.

The order includes a 225t/hr bucket elevator with a BWZ-L (low capacity) central chain type and a centre distance of 27m to feed the raw meal mill as well as three different models of BWG belt bucket elevators with capacities up to 500t/hr and centre distances up to 132m. The belt bucket elevators will also be used for raw meal silo feed as well as to transport raw meal to the dosing hopper and the heat exchanger. The order also includes three KZB type pan conveyors, each with capacities of 350t/hr and centre distances of up to 77.2m to convey clinker from the cooler to the silo, as well as two LOUISE BEW type rotary discharge machines, each with a diameter of 3m and a capacity of 400 t/hr.

US: CalPortland has commissioned a new cement grinding mill and distribution system at its Oro Grande cement plant in California. The US$58.5m project includes the construction of the finish ball mill and two new cement shipping lanes with two new distribution silos. It completes a partial plant modernisation program that was originally completed in 2008, prior to the acquisition of the facility by CalPortland. The Oro Grande cement plant was purchased from Martin Marietta Materials in mid-2015.

“The addition of this modern finish mill and efficient distribution system allows the plant to operate to the best in class standards as originally designed. It will help provide the industry with the additional supply required for necessary rehabilitation and rapidly developing infrastructure in California and Nevada,” said Steve Regis, Senior Vice President Corporate Services, CalPortland.

The project began in January 2018 and was constructed by general contractor ThyssenKrupp and sub-contractor TIC (The Industrial Company), in collaboration with CalPortland’s Engineering Services team.

The mill is a Polysius two compartment mill with production capability of around 180t/hr. It is equipped with motor, mill and separator technology as well as cement cooler design technology. The system also employs mechanical conveyance (bucket elevator) to convey finished product to the new silos, reducing its energy requirements. These additional systems are being added to the Oro Grande plant.

Guatemala: Cementos Progreso says that its new San Gabriel cement plant is currently being tested. Plant manager Heber Barrios Valenzuela said that this stage of its set-up began in 2018 and will continue throughout 2019, according to the Prensa Libre newspaper. The unit had an investment of US$500m. Work on the project started in 2008 and construction work began in 2013.

The new integrated cement plant will have a clinker production capacity of 4500t/day when fully operational. Key features include a 1.5km conveyor from the quarry to the plant with a capacity of 1000t/hr. After raw material grinding, pre-heating, the kiln and the cooler the production line has a 70,000t clinker silo. This is followed by two vertical cement grinding mills, each with a capacity of 220t/hr. For packaging and despatch the plant has four cement silos. Two of these have a capacity of 10,000t for bulk cement. The other two have a capacity of 5000t for bagged cement. The plant also uses a 0.15Mm³ rainwater reservoir to store water to cool machinery.

Sweden: Conveyor belts supplied by Germany’s Continental are being used in the Förbifart Stockholm road infrastructure project. HeidelbergCement’s aggregate company Jehander is using Continental steel cord conveyor belts at its Löten quarry near Stockholm to allow rubble from tunnelling to be reused for road construction. In addition, drilling machines from Epiroc are using Continental DrillMaster tyres to provide high cut resistance, good traction and stability.

Overall, around 5.5Mt of rock will be extracted to build the tunnels required for the new bypass. A series of conveyor belt systems are being used to transport the extracted rock to three temporary ports that have been set up for the project. The rubble is taken across the waterways by inland vessels from the construction site in Stockholm to Löten. The rubble is then reused as concrete, mostly for road construction, or it used for local construction.
