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.

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.

Pakistan: Flying Cement has ordered a 71-6 OK model cement mill from Denmark’s FLSmidth for its new 7700t/day production line at its Mangwal plant. The mill will be designed to grind Ordinary Portland Cement (OPC) at a capacity of 415t/hr. Commissioning is expected in 2020, and the mill will be supplied together with an FLSmidth ILC Preheater System, 2-Base Kiln, Cross-Bar Cooler, ROKSH 119 Separator, MAAG WPV-5000 Gear, Heat Exchanger and three filters. No price for the order has been disclosed.

Denmark: FLSmidth says it sold 31 new vertical roller mills (VRM) in 2018 for all grinding applications. The combined cement grinding capacity of its OK Mills VRM product line grew by over 38% year-on-year to 3145t/hr in 2018 from 2270t/hr in 2017. The average grinding capacity per sale of OK Mills for the cement industry grew by almost 10% to 225t/hr from 206t/hr.

The Danish equipment manufacturer installed its first OK Mill in 1982. To the end of 2018 it has sold 184 mills. It has supplied VRMs to 67 countries around the world since the OK Mill launched. Since the start of 2017 OK Mills have been sold in Indonesia, the Philippines, Algeria, Turkey, the UK, Pakistan, Nigeria, Kenya, Peru, Cuba, India, Nepal, Algeria and Egypt. Shah Cement in Bangladesh inaugurated in 2018 an 81-6 OK Mill, the world’s largest vertical roller mill for cement grinding. It featuring six rollers and an 8.1m diameter grinding table.

Uzbekistan: Russia’s Eurocement has ordered three mills from Germany’s Gebr. Pfeiffer for its Akhangarancement plant upgrade in Uzbekistan. The package includes an MVR 5000 R-4 for raw material grinding and two MVR 5000 C-4 for cement grinding. The MVR 5000 R-4, features a total drive power of 2500kW, will grind 500t/hr of cement raw material to a fineness of 12% R 90µm. The cement mills, each with an installed drive power of 4000kW, are designed to grind 200t/hr of Ordinary Portland Cement (OPC) at 3200 Blaine. No value for the order has been disclosed.

China: Japan’s Kawasaki Heavy Industries has delivered two 220t/hr CK Mills to Jiande Conch Cement via Anhui Conch Kawasaki Energy Conservation Equipment Manufacturing (CKM), a joint venture between Kawasaki Heavy Industries and Anhui Conch. Kawasaki is handling design and operation-related technical guidance, whereas CKM is in charge of manufacturing and delivery. The mills have a table track diameter of 4900mm, 5100kW motors and four rollers. No value for the order has been disclosed.

Kuwait: ACICO Cement has ordered a second cement grinding mill from Spain’s Cemengal. The main equipment to be included in the contract includes a 5200 Kws ball mill with all the peripheral equipment from Cemengal and a fourth generation classifier from Magotteaux XP4i-130 for high strength cements. The projected grinding capacity will be 1Mt/yr of cement and the plant will be commissioned within the first half of 2020.

The project scope will include full engineering and complete supply of mechanical, process, electrical and automation equipment as well as the steel manufacturing from the raw materials handling areas up to the cement silos discharge. Site supervision, training and& commissioning will also be provided by Cemengal.

Peru: Chile’s Cementos Bío Bío plans to build a US$20m grinding plant at the Port of Matarani near Arequipa. The cement producer has all the necessary permits in place and it intends to open the unit in the first half of 2020, according to the Diario Financiero newspaper. Spain’s Cemengal will supply a Plug & Grind mill for the project. The plant will have a production capacity of 0.2Mt/yr, although there are plans to double this if the market supports it.

Chile: Spain’s Cemengal has been confirmed as the supplier of a mill for Cementos Melón’s grinding plant at Punta Arenas. The unit will use a Plug & Grind Xtreme modular grinding plant. The contract includes all the mechanical, electrical and automation equipment required for a 0.3Mt/yr modular ball mill and a classifier. Cemengal will deliver the mill by the end of 2019 to allow first cement and commissioning of the plant in the first quarter of 2020.

Russia: Eurocement is planning a second phase of upgrades for its Kavkazcement plant in 2019. These include starting to generate its own electricity, modernising its cement grinding mills, completing a maintenance campaign and moving to solely operating rotary kilns. The first phase of the upgrade project saw the plant build a slurry pipeline, construct the building for a captive power plant and purchasing monitoring equipment.
