China/France: Song Zhi Ping, president of China National Building Material Company (CNBM), and Frédéric Sanchez, chairman of Fives, have signed strategic agreement towards climate change and cooperation in third countries. This agreement develops the collaboration plans drawn up in January 2019 between cement plant manufacturer CNBM the engineering group Fives. It forecasts a volume of business of at least Euro600m over three years, and forms part of CNBM’s stated strategy of developing in partnership with western companies. The agreement was signed at the Elysée Palace in Paris during a state visit to France by China’s President Xi Jinping.

The agreement focuses on upgrading CNBM’s cement plants in China, building new plants outside of China and creating a Joint Engineering Centre to implement these projects and share information. The Joint Engineering Centre was inaugurated on 28 February 2019 in Shanghai. With regards to modernising its cement production lines in China, Fives said that its technologies, in grinding in particular, would ‘significantly’ improve performance and return on investment with regards to modernising CNBM’s domestic cement production lines. Fives said that the agreement is in full alignment with the Paris Agreement. It added that the agreement also shows the ‘mutual trust’ between the two companies with respect to intellectual property.

India: KCP has commenced commercial cement at the new 1.7Mt/yr line at its Muktyala plant in Andhra Pradesh. With this expansion, the total capacity of the plant has reached 4.3Mt/yr. The company has also started up its 0.5Mt/yr grinding plant project in Naidupeta, Nellore District, Andhra Pradesh.

Europe: US-based company GCP Applied Technologies has received a European patent for increasing the efficiency of cement grinding by using sustainable raw materials. The grinding aids and quality improvers allow the use of bio-derived glycerol and reduce the use and the impact of oil-derived chemicals. The new Opteva and Tavero brand cement additives enable cement producers to reduce the energy consumption and the CO₂ emissions associated with cement production, with a reduced use, or no use at all, of oil-derived chemicals.

European Patent No. EP 1 728 771 B1 has been granted and registered into 17 European countries. The patent addresses methods for increasing the efficiency of cement and mineral grinding by using sustainable raw materials.

The patent relates to methods for improving the efficiency of grinding materials such as clinker and limestone, using glycerol derived from biofuel production, in combination with various grinding additives. GCP products can help to reduce the carbon footprint of cement and concrete. Grinding aids and quality improvers make cement manufacturing more efficient, while concrete admixtures can reduce the amount of cement needed to achieve a given strength specification.

South Africa: Magotteaux International has become a strategic equity partner in Grinding Media South Africa (GMSA). The decision follows an agreement between the Industrial Development Corporation (IDC) and Magotteaux on extending their partnership in GMSA. GMSA, a newly created company spun out of industrial group Scaw Metals, specialises in the manufacturing and design of grinding balls for use in the mining, cement and utilities industries.

The partnership will also enhance the technical and financial capacity of the business as well as provide access to new growth markets. As part of this partnership, Magotteaux will assume the operational management of GMSA upon conclusion of the agreement.

“Magotteaux has been collaborating closely with Scaw High Chromium grinding media for more than 30 years”, said Sébastien Dossogne, chief executive officer (CEO) of Magotteaux.

India: With a merger of LafargeHolcim subsidiaries ACC and Ambuja Cement on hold, the two companies have proposed entering into a Master Supply Agreement (MSA) with each other with the aims of increasing synergies, reducing operational costs and increasing the companies’ joint sustainability.

This agreement is for supply of cement, clinker, raw materials (including fuel, fly ash, slag, gypsum etc), spare parts and for providing toll grinding services at certain plants. This will be executed through purchase orders, subject to a pricing formula. This will enable each company to optimise the cost of servicing markets by using each other’s plant’s capabilities, maximise the utilisation of assets to generate additional sales for each company and make best use of their joint spare inventory.

UK: Welding Alloys has launched MillCarb, a repairable welded ceramic composite alloy providing an engineered wear protection solution for grinding components. It combines the wear resistant properties of advanced and complex ceramics with graded grain sizes and the shock absorbing properties of a metallic matrix, creating a ceramic metal matrix composite. The company says that these features have been incorporated into a weldable solution that is capable of multiplying the life of components by offering a repairable alternative. MillCarb is currently being trialled with industrial partners.

Bolivia: Cooperativa Boliviana de Cemento, Industrias y Servicios (COBOCE) has ordered an OK 43-4 vertical cement mill from FLSmidth for its Irpa Irpa plant near Cochabamba. The unit will have a production capacity of 130t/hr. The order includes a complete range of equipment from mill feeding bins, grinding and cement transport. FLSmidth will also supply equipment from its product brands, such as planetary gear units from FLSmidth MAAG Gear, fabric filters from FLSmidth Airtech, a control system and plant automation from FLSmidth Automation.

“We are proud to deliver the first cement vertical roller mill to COBOCE making it the third out of five Bolivian suppliers choosing our cement vertical roller mill technology. This order underlines FLSmidth’s strong position in Bolivia,” said Per Mejnert Kristensen, Group Executive Vice President, Cement Division.

India: Ramco Cements is planning to make an investment of about US$172m in various projects, on the back of anticipated higher demand for cement in the near future. The company will invest in a range of projects, including expansion of its satellite grinding unit capacity. This move will enable the company to increase its presence in Odisha, Andhra Pradesh and West Bengal and will raise its total capacity to 7.1Mt/yr from 4.0Mt/yr at present. Expansions will be undertaken at its Visakhapatnam and Kolaghat plants, as well as at a new new grinding unit in Odisha. The projects will be commissioned within 18 months.

Australia: Boral Cement has ¬applied to the Environment Protection Authority (EPA) to run a 1.3Mt/yr cement grinding plant at Geelong in Melbourne, Victoria for 24 hours per day. The proposed facility would enable the company to unload from ships to be delivered to the production site via covered belt conveyors.

“The new site is directly adjacent to the wharf complex, which would allow efficient unloading of clinker from ships,” a Boral spokesman said when the company first raised the concept in late 2016. “Importantly, the site is also surrounded by other large industrial premises, meaning it is well separated and largely hidden from residential areas.” Boral has also proposed constructing new equipment, including an enclosed ball mill and covered store, outdoor product stockpiles and clinker unloading and delivery infrastructure.

EPA development assessments manager Tim Faragher said that Boral Cement required a works approval before starting any construction works on the clinker grinding mill. “Work approvals are ¬required for industrial and waste management activities that have the potential for ¬significant environmental impact,” said Faragher. The EPA now has four months to make a decision on Boral’s application.

Cameroon: Cimencam, a subsidiary of LafargeHolcim via LafargeHolcim Maroc Afrique (LHMA), has announced that it will build a 0.5Mt/yr cement grinding plant at Nomayos, near Yaoundé with a budget of Euro42.6m. The plant will be the cement producer’s third in the country, according to the Échos Quotidien newspaper. Cement from the new plant will be sold locally as well as elsewhere in Central Africa. LHMA owns a 54.74% share in Cimencam.
