Mexico: Holcim Mexico has announced a forthcoming investment of US$40m in the construction of a 0.7Mt/yr grinding plant in the state of Yucátan. Jamie Hill Tinoco, general director of Holcim Mexico, said that the plant, which will receive clinker from Holcim Mexico’s Macuspana and Orizaba cement plants, signifies the company’s commitment to the state, enabling it to ‘optimise local solutions with greater benefits for customers and communities.’ The plant will be Holcim Mexico’s sole dedicated grinding unit in an integrated cement production apparatus totalling 11.8Mt/yr capacity.

Holcim has had a presence in Yucatán since 1992 through its Uman distribution centre.

Oman: Raysut Cement is planning the construction of a 1Mt/yr grinding plant in the port town of Duqm. The project has a cost of US$30m, with work set to begin on 19 September 2019. Oman Cement has been building a 1.8Mt/yr integrated cement production plant at Duqm since December 2018. The new grinding plant is Raysut Cement’s first development project since it received US$50.7m in funding from the Omani Bank Nizwa.

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.
