Sri Lanka: The Industry and Commerce Ministry has expressed its interest in buying the local operations of LafargeHolcim. Government sources have said that discussions are now on-going within the administration. The multinational cement producer announced in early June 2016 that it was selling its subsidiary Holcim Lanka. The company was originally state-owned before it was privatised.

"The government is willing to negotiate to buy it at a reasonable price. This is the only integrated cement plant in Sri Lanka. The limestone quarry in Puttalam belongs to the Cement Corporation and it had been leased out to Holcim," said a spokesman of the ministry quoted by the Daily News newspaper. He added that no final decision on the matter has been taken yet. The government also hopes that, if it successfully purchased the company, it could reduce the price of cement in the country.

Local press reports that seven bidders have made offers for Holcim Lanka. These include companies from UAE, Indonesia, Thailand, China and Sri Lanka. Holcim Lanka’s assets include two packing plants in Galle and Trincomalee, a cement plant in Puttalam and a cement grinding plant in Galle.

Indonesia: PT Krakatau Semen Indonesia has ordered a slag grinding mill from Loesche for its Cigading grinding plant in Cilegon, Banten. Krakatau Semen will use a Loesche mill with an LDC classifier to grind ground granulated blast furnace slag to a fineness of 4500cm²/g. The scope of supply for this contract also includes the raw material transport system, the mill dust extraction system, the reject system and the silo equipment. The mill is scheduled for operation by the first quarter of 2017.

Subsidiaries of Loesche are participating in the contract. Loesche ThermoProzesstechnik is supplying the grinding plant with a hot gas generator type LF-36L (fully inline) for the combustion of industrial diesel oil. Automation of the plant is supplied by Loesche Automatisierungstechnik. Loesche Indonesia will provide a service contract including personnel services. In addition, Loesche will monitor the local production as well as the assembly and commissioning.

PT Krakatau Semen Indonesia was founded in November 2013 as a state-run company. In a joint venture with PT Semen Indonesia, PT Krakatau Semen Indonesia is building its first plant of this type with a planned production of 0.75Mt/yr.

India: Ambuja Cement has completed a 0.9Mt/yr capacity upgrade at its Sankrail grinding plant in West Bengal. The US$50m upgrade was commissioned on 24 May 2016.

Philippines: Republic Cement has inaugurated its new cement grinding mill at its Norzagaray cement plant in Bulacan. The US$19m expansion will add 0.85Mt/yr of cement production capacity to the plant, according to the Philippines Star.

“This capacity expansion initiative reaffirms Republic Cement’s commitment to support our country’s growth through the provision of top quality cement and building materials,” said Renato Sunico, president of Republic Cement. The new mill will also decrease the plant’s energy consumption.

Republic Cement, formerly Lafarge Republic, is owned by a joint venture of Aboitiz Equity Ventures and CRH.

Germany: Clariant Germany has purchased the first mobile Loesche grinding plant to grind bentonite at its Balikesir facility in Turkey. Clariant required a mobile plant because the site is due to be relocated. The mill is integrated into seven ISO containers, all the electrical connections between the containers are pluggable and no foundations are required for its erection on solid ground. The mill is expected to be commissioned in May 2016.

The vertical roller mill uses a type LM 9.2 D mill, it is designed for grinding industrial minerals and it has a capacity of 1.8t/hour. The Balikesir facility grinds bentonite, which is ground to a fineness of 30% R 0.063. The grinding plant has a power transmission capacity of 45kW. All grinding plant components from the open loop control to the feed bin, the crusher, the mill with classifier, the hot gas generator, the filter, the fan and the pneumatic product transport are placed in containers.

Clariant is a global leader in specialty chemicals. Its headquarters are in Muttenz near Basel in Switzerland.
