Russia: Mordovcement, part of Eurocement Group, has commissioned a new bagging line using equipment from Newtec Bag Palletizing and OMS Systems. The pallet-free palletiser has a rate of 130t/hr or 2600 bags/hr processing bags of 40kg or 50kg. The cement producer invested over Euro950,000 on the new line and the upgrade is expected to increase the plant’s cement delivery volume to 9000t/day.
Guinea: Guinee Industries Ciments (GIC) has awarded KHD Humboldt Wedag a contract to upgrade its cement grinding plant located in Conakry. GIC will integrate a Comflex system into GIC’s existing ball mills. The system will be the third Comflex system with roller press technology that has been installed in West Africa. The new system is expected to double the production capacity of the grinding line.
KHD’s scope includes the engineering and delivery of mechanical and electrical equipment, as well as the supervision of erection and commissioning for the new Comflex SC16-3500. The core equipment includes a RPS 16-170/180 roller press with Rolcox system for control and monitoring, a VS 620 cascade separator as a static classifier, a SKS-VC 3500 Sepmaster separator as a dynamic classifier and a HKSK 212-275 system fan. Commissioning of the Comflex system is scheduled for the end of 2017.
Paraguay: President Horacio Cartes has officially opened a US$3.9m pozzolana dryer at Industria Nacional del Cemento’s (INC) cement grinding plant at Villeta. The upgrade cost US$3.9m and it is expected to save the plant up to US$10m/yr, according to the Última Hora newspaper. In addition the cement producer is changing the fuels it can use at its Vallemi cement plant.
Burkina Faso: Intercem has reported that it replaced the main transformer at the Cimfaso Cement plant in 10 days in February 2017 from the initial order to the resumption of production at the unit. Following a problem with the local power grid the transformer was damaged and production stopped. Intercem dismantled and flew the transformer from Germany to Burkina Faso and then supervised its reassembly, connection and commissioning including customs and visa clearance.
Pakistan: Flying Cement plans to double the production capacity of its Lilla cement plant in Mangowal, Punjab. It has struck an agreement with an undisclosed Chinese contractor to upgrade the plant’s clinker capacity to 4000t/day from 2000t/day. No value for the deal has been released. The plant has a cement production capacity of 0.63Mt/yr. It was originally supplied by Japan’s IHI.
UK: Hanson is considering spending around Euro23m on building a new clinker mill and other improvements at its Padeswood Cement plant. At present the site use four mills that are only able to grind about 40% of the kiln’s output, according to the Daily Post. A second phase of the upgrade project, dependent on production levels being increased, is planned to rebuild a railway link to the plant.
Mexico: Fives has supplied a Fives FCB Horomill for the new production line at Cementos Moctezuma’s Apazapan plant in Veracruz. The cement producer signed the acceptance certificate in mid-February 2017. The FCB Horomill 3800, supplied to fit the raw meal-grinding workshop, is part of the new plant that was inaugurated by Cementos Moctezuma in January 2017.
Denmark: Aalborg Portland has awarded A Tec a contract to upgrade its Cement Kiln 87 in Aalborg. It has ordered two calciners for its 4500t/day semi-dry kiln system that was commissioned in 1988. The calciners will be designed and delivered during the kiln’s annual stop in February and March 2017. Commissioning is planned for the spring of 2017. The upgrades are intended to increase production of Ordinary Portland Cement on the line.
A Tec intends to adapt the flow pattern of the calciner system in a way to improve the operational behaviour of the system. The design will be configured for the usage of 100% solid alternative fuels with low emissions. Additionally, the number of kiln stops due fall through cyclone blockages should be reduced. A Tec will conduct the engineering, supply the equipment and will be responsible for errection and documentation.
The new calciner system will be equipped with the A Tec Post Combustion Chamber (PCC) for the optimised mixture of fuels and combustion air in the end section of the calciner. The PCC was specially developed for the achievement of complete combustion of alternative fuels at high substitution rates.
South Korea: SsangYong Cement has awarded a contract to Claudius Peters Projects for the supply of a grate cooler modification. The existing cooler at the Donghae cement plant will be upgraded by with an ETA 5th generation clinker cooler system. It consists of a fixed inlet, the High Efficiency module (HEM) and a moving floor ETA technology. It is designed for a stable production at 7600t/day.
SsangYong cement was established in 1962 and operates the world’s largest cement plant in Donghae with a capacity of 11.5Mt/yr of clinker. It employs around 400 workers.
South Korea: Voith has reported on a contract to engineer and install a belt conveyor drive and controller system for SsangYong Cement’s Donghae plant. Changes made by the engineering firm to two belt conveyors from the main limestone quarry to the plant managed to double the production of the quarry.
The engineering company installed new drive trains on the longer 12.8km SB500 belt conveyor, one of the longest single conveyors in the world. The installed power is now 2 x 1.2MW at the head and 1 x 1.2MW at the tail of the conveyor. The existing drives from the longer conveyor were used to double the number of drive trains on the shorter 2km SB200 conveyor. The new configuration of the SB200 drive system consists of 4 x 600kW installed power at the head equipped with new gearboxes. A Voith TurboBelt DriveControl system was also installed to reduce the start-up time of the longer conveyor by half, from originally over 10 minutes. The system includes active-load sharing, belt conveyor control, slip detection and remote service capability. It is also expected to extend the belt lifetime by reducing the mechanical stress as well as the dynamic impacts.
“Due to this retrofit project, we were able to reduce the working hours of plant workers, achieved cost savings, and a flexible operation is now possible. Thanks to Voith’s technical support and efforts, the plant will enjoy sustainable operations providing value to its community, its owner, and the employees,” said Dukgi Lee, General Manager of the plant.
