UK: Hanson Cement says that the first phase of a Euro27m upgrade project to its integrated Padeswood plant in Wales has been completed. The upgrade has included the installation of a 0.65Mt/yr cement grinding mill as well as enhancements to production capacity and efficiency gains. The plant can now, with the aid of existing ball mills, match cement grinding with its kiln capacity.

“The nearly new Loesche vertical roller mill, housed in a 34m-high building, started its life at a grinding plant in Bilbao. It had only 7000 operational hours on the clock and was in excellent condition. After dismantling it piece by piece, specialist contractors moved it to the UK where it was reassembled on site at Padeswood,” said Jim Claydon, Hanson UK cement managing director.

Other improvements at the site include the installation of three new rail cement silos that have been installed alongside the existing railhead. This will allow up to three trains a week to be loaded for deliveries to Hanson depots in London, Bristol or Glasgow. The new silos will reduce the transportation of cement produced at Padeswood to customers by road. In addition to the increase in grinding capacity, other recent capital investment at Padeswood include the installation of a plastic packing machine, and the re-commissioning of an existing paper packaging machine and an upgrade in the capability to use recycled paper and plastics as fuel.

Kenya: Mombasa Cement has ordered a MVR 3750 C-4 type vertical roller mill from Germany’s Gebr. Pfeiffer. It will be used to grind cement on the second production line it is building at its integrated Vipingo plant. The mill has a drive power of 2900kW to produce 150t/hr of Ordinary Portland Cement (OPC). Delivery will be coordinated between Gebr. Pfeiffer’s Indian subsidiary and its headquarters in Kaiserslautern, Germany. No value for the order has been disclosed.

The cement producer has previously ordered two cement mills from Gebr. Pfeiffer. In January 2016 it ordered a type MVR 3750 C-4 vertical mill for the Tororo plant in Uganda. In June 2016 it ordered a Ready2Grind type MVR 1800 C-4 mill for its Vipingo plant. The latest order at Vipingo has the same design as the mill in Uganda.

Burkina Faso: Harouna Kaboré, the Minister of Commerce, Industry and Handicraft, has inaugurated a new mill at Cimburkina’s cement grinding plant at Kossodo in Ouagadougou. By installing the new mill the unit has doubled it production capacity to 2Mt/yr, according to the Sidwaya newspaper. The upgrade cost US$25m.

François Sangline, the director general of the subsidiary of Germany’s HeidelbergCement, said that the 2000t limestone silo feeds the production line consisting of two 150t/hr cement grinding mills. This is followed by a 120t/hr bagging unit. Sangline noted that the country’s cement consumption of 2.5Mt/yr is below the domestic cement production capacity of 6Mt/yr. Due to this he lobbied the government to protect local production against imports and fraud.

Guinea: LafargeHolcim Guinea has ordered a MVR 2500 C-4 vertical roller mill from Germany’s Gebr. Pfeiffer for its Sonfonia cement grinding plant in Conakry. The cement mill will have a total drive power of 1300KW. It has been designed to grind 75t/hr of CEM IV 32.5 and 69t/hr of CEM IV 42.5 to a specific surface of 3440cm²/g and 3340cm²/g acc. to Blaine respectively. The order for the mill was placed by the China’s CBMI working as a general contractor on the project. No value for the order has been disclosed.

Algeria: Algematco Steel, part of Rahmoune Group, has ordered a modular Ready2Grind MVR vertical roller mill from Germany’s Gebr. Pfeiffer. Erection and commissioning of the unit are scheduled for early 2020. No value for the order has been disclosed.

The cement grinding plant includes: a feed module with material dosing and transport; a MVR 2500 C-4 type vertical roller mill with a SLS 2650 BC ctype lassifier and drives; plant filter, fan and hot gas generator; electric switchgear with plant control system; silo plant; packing and palletising plants; and laboratory equipment. The plant is designed to produce different cement types at a production rate of 50 - 70t/hr.

Togo: HeidelbergCement is considering investments of up to Euro25m in its local subsidiaries including Cimtogo, Scantogo and Granutogo. Local director general of the company Eric Goulignac outlined the plans, including building and installing a new mill at Cimtogo’s cement grinding plant in Lomé and a photvoltaic (PV) solar energy plant, according to the All Africa news agency. The projects will be considered by the board of HeidelbergCement in the summer before a final decision is made.

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.
