Kuwait: Kuwait Cement has hired Belgium’s Magotteaux to modernise three of its cement mills. The project consists of closing the open circuit with fourth generation XP4i separators, installing new mill internals components, including diaphragms, and adapting a new ball charge gradation. The aim of the project is to increase the production rate, reduce the specific energy consumption and improve the product quality, by reducing the residue on 45μm by keeping the same Blaine value.

Uzbekistan: Qizilqumsement has started building a US$110m upgrade to its Qizilqum cement plant. The project is intended to increasing the plant’s clinker production capacity and decrease energy costs. It is scheduled for completion in 2020.

Afghanistan/Uzbekistan: Uzbekistan’s Almalyk Mining and Metallurgical Complex (AMMC) has started exporting cement to Afghanistan. A trial consignment of Ordinary Portland Cement (OPC) was despatched from the company’s new 1.5Mt/yr Sherabad cement plant in Surkhandarya, according to the Trend News Agency. It intends to export 0.5Mt/yr to Afghanistan. As part of a contract signed with the Hamid Company just under 1000t of cement has been sent by train to Mazar-i-Sharif.

France: LafargeHolcim France has started the second phase of a Euro100m upgrade project its Martres-Tolosane cement plant. It is starting the construction phase of a new production line following the completion of site preparation and civil engineering. French company Boccard is coordinating the work. Commissioning of the upgrade is scheduled for mid-2020.

Russia: Eurocement is close to completing a Euro2.5m upgrade to a cement grinding mill at its Katavsky cement plant. The project was intended to improve the quality of its cement products and to replace the mill’s filter sleeves. The unit uses which Christian Pfeiffer separators, Aumund elevators, Siemens automation systems and mill grinders and Vega grinding media. Pre-commissioning is currently being completed and cement from the mill is being tested at a laboratory.

The cement producer’s Kavkaztsement plant is building a captive power plant scheduled for commissioning in August 2019. It has completed the construction of the building that will house the gas piston power station as well as other connecting structures. Employees from the plant are being trained by Wärtsilä in preparation for the start up. The project has an investment of around Euro15m.

US: A fire has damanged Dragon Products’ Thomaston cement plant in Maine. The incident took place on evening of 26 March 2019 following a spill of fuel oil, according to the Portland Press Herald newspaper. The blaze was stopped by firefighters as it started to enter a laboratory and control rooms. No employees were injured.

Plant manager Martin Turecky said that no customers would be affected by the fire and that it was continuing to distribute cement. He added that the cement grinding plant had not been affected. An investigation into how the fire started is underway.

Argentina: Loma Negra has secured two loans to upgrade its L'Amalí cement plant. The loans are worth US$40.9m and US$12.5m respectively, according to the Bae Negocios newspaper. The cement producer will use the funds to import equipment to the plant as part of a project to build a new US$350m production line at the unit.

Sri Lanka: Tokyo Cement has agreed to amalgamate its subsidiary Tokyo Super Cement into the main company. The amalgamation of its wholly-owned subsidiary will take place around the end of May 2019.

Germany: Siemens is extending its Simogear portfolio with a new synchronous-reluctance drive system consisting of Simogear standard gear unit, Simotics reluctance motor and a Sinamics frequency converter for controlling speed. The product has an output range of 0.55 – 4kW and is available for Sinamics G110M, G120D, G120 and S120 converters.

The engineering company says that its efficiency class is comparable to IE4 and it is offers advantages in comparison to asynchronous motors when operating under partial load due to its greater efficiency and lower losses. In addition, the drive system is characterised by high dynamics due to the low moment of inertia and optimised control. An external fan is not required due to the constant torque/speed curve up to the nominal speed and the drive system is certificated to CE, UL/CSA and CCC is in preparation. It also says that commissioning is easy as the motor code can be entered into the convertor.

Siemens sells a portfolio of frequency converters, motors, couplings and gearboxes for many industries and applications, including the cement and mineral sectors.

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.
