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.
