Algeria: Fives installed the first FCB B cement grinding mill in early April 2017 at Entreprise des Ciments et Dérivés d’El Chellif’s (ECDE) 6000t/day clinker production line at Chlef. Installation of the mill followed the erection of the FCB kiln (Ø 5.1 x L 82m) in February 2017. A heavy lifting jack crane system sliding on rails was required to install the 4.8 x 17.8m shell and 98.5t gearbox inside its specific finished building. Grinding mills no. 2 and no. 3 will be installed next to complete the cement grinding mills at the unit. Once complete it will include three 160t/hr FCB B-mills with 5320kW drives and associated FCB TSV4500 HF classifiers. ECDE is a member of the industrial group Ciments d’Algérie (GICA).

Philippines: Republic Cement is expanding its grinding capacity by over 10% in anticipation of a rise in demand prompted by increased government infrastructure spending.

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.
