Egypt: The Arabian Cement Company plans to spend US$5.7m on a new coal mill for its Suez cement plant. The upgrade is intended to increase production capacity at the site, according to the Daily News Egypt newspaper. At present the plant is operating at 60% capacity by using one coal mill. It imports coal from Europe, China and South Africa through the Dekheila Port of Alexandria and Adabiya Port in Suez.

The cement producer reported that its net profits fell by 36% year-on-year to US$8.97m in the first nine months of 2016 from US$14.1m in the same period in 2015. It blamed this on foreign exchange rates and a drop in sales due to technical problems at the plant.

France: Ecocem France has ordered a Loesche type LM 46.2+2 CS mill for a slag cement grinding plant that it is building in Dunkirk. It follows a previous order by Ecocem of a LM 46.2+2 CS mill for the dry grinding of ground granulated blast furnace slag (GGBFS) at its plant at Fos-sur-Mer.

The LM 46.2+2 CS for the plant in Dunkirk is designed for the grinding of cement clinker and granulated blast furnace slag at a capacity of 105t/hr GGBFS. The gearbox will have a capacity of 3150kW.

All the mechanical equipment for the grinding plant starting from mill feed to the product discharge into the product silos is included in the Loesche scope of supply. The Loma heater type LF 28-L will be a full-inlined type designed to burn natural gas as well as blast furnace gas. The burner supplied by Loesche will be the MSBZ type, complete with fitting rack and local switch cabinet.

The lead-time for the main components of the mill and for the additional units included in the scope of supply is 6 to 13 months. The commissioning of the vertical roller mill is planned for the middle of 2017.

Ecocem’s grinding plant will be installed close to Arcelor steelworks for use of their granulated blast furnace slag. This LM 46.2+2 CS will be the seventh Loesche vertical roller mill installation for slag and cement grinding in France.

India: Star Cement has ordered upgrades for the 70t/hour ball mill, with a diameter of 3.6m and length of 11.9m, at its plant in Meghalaya from KHD. The equipment manufacturer will supply a roller press RP7-170/90 along with an SKS VC 3000 separator, which will increase the grinding capacity of the current ball mill by more than 100%.

Lebanon: Intercem is building a hot gas system for a coal mill at the LafargeHolcim Chekka plant. The engineering company won the contract for the job in 2015. It is the second such contract for Intercem to build a hot gas system following a previous project at a plant in Jordan in 2013.

The new hot gas system in the coal mill plant in Chekka connects the preheater with the coal mill and comprises a hot gas duct with a length of 360m and a diameter of 900mm. The process data of the hot gas outlet of the heat exchanger are of 18,500Nm³/hour at 400°C.

The turnkey scope of supply and services for the project includes:

• Project management
• As-built-survey of the existing plant using 3D-Laser scanning
• Review of the statics of the existing steel structure and concrete construction
• Process- and detail engineering
• Supply of the mechanical equipment including steel structure
• Coordination of the locally produced components
• Supply of the electrical equipment including clarification of connections and integration into the existing control systems
• Execution of the complete foundation works
• Transport management
• Electrical and mechanical assembly of the plant
• Commissioning of the hot gas system
• Training of the operating team

In addition ducts, a cyclone, a process fan and several control dampers, compensators, the complete instrumentation and automation as well as a new recirculation duct with two control dampers at the existing vertical coal mill have been supplied.

Handover to the customer is planned for fourth quarter of 2016.

Vietnam/Germany: Loesche GmbH has won an order for a new cement grinding plant in Ha Nam. The customer is Xuan Thanh Cement Joint Stock Company, a private company group (est. 1976) in Vietnam with more than 30,000 employees. In December 2015, Xuan Thanh Cement decided to invest in a new cement line from FLSmidth. Germany's Loesche GmbH, however, was chosen for the delivery of the cement mills.

After Loesche had already supplied a vertical roller mill for the first cement line in the same plant, Xuan Thanh JSC placed the order for the construction of the new grinding plants with two cement mills with Loesche once again.

During the signing ceremony, Mr Nguyen Xuan Thuy, General Director of Xuan Thanh Cement JSC, thanked Dr Thomas Loesche on behalf of the Xuanh Thanh Group. The contracting partners discussed future developments and confirmed their interest in continuing to work together on a long term basis.
The challenge of this project for Loesche lies in the integration of the new grinding plants into a cement line which is presently under construction.

The key elements of the scope of supply are two cement mills type LM 56.3+3 CS. In addition to the two cement mills, Loesche is also supplying further plant components, from the fresh material supply, the product filter and the mill fan to the finished material transport to the product silos. Loesche Automatisierungstechnik GmbH will be the supplier for the electric part and the automation of the grinding plants. Two hot gas generators type LF 20 L are designed to provide the product moisture guaranteed in case of kiln standstill. An extensive engineering package provided by Loesche will conclude the scope of supply.

Xuan Thanh cement plant will thus be fitted with state-of-the-art equipment for low energy consumption and for reduction of emission values to European standards. The lead time for the entire package is eleven months. Commissioning is forecasted for the second quarter of 2017.

Nepal: Shubhashree Agni Cement Udhyog has placed an order for a Loesche Mill LM 35.2+2CS for the cement grinding section of its 700t/day integrated plant being built at Jaluke-6, district Arghakhachi. The order is Loesche India’s first in Nepal.

The order scope includes a mill fan and metal detector. The mill, designed for grinding Portland Slag Cement, will produce at a capacity of 62t/hr with a fineness of 3500 Blaine. The mill will also produce Ordinary Portland Cement and Portland Pozzolana Cement at capacities of 60t/hr and 76t/hr respectively. The mill will be delivered in a period of 10 months.

Other installations of the LM 35.2+2CS have been in operation at Deccan Cement, Bhavanipuram, since 2001, and to Sri Balaha Chemicals’ Hindupur plant for grinding slag at 4000 Blaine.

Loesche India has sold over 110 vertical roller mills for the grinding of raw material, coal and cement to various clients in India and South Asia. It is based in Delhi, National Capital Region.

Nepal: Arghakhanchi Cement plans to spend US$38.5m to increase both its clinker and cement production capacities to 3000t/day by October 2017. At present the plant has a clinker capacity of 1200t/day and a cement capacity of 1000t/day, according to the Kathmandu Post. Managing director Rajesh Agrawal added that the company has signed a deal worth US$9.32m to order vertical roller mills from FLSmidth as part of the upgrade.

Local industrial groups Siddhartha, Murarka and Kedia hold stakes of 35%, 30% and 17.5% respectively in the cement producer. Uma Cement, an Indian company, owns the remaining 17.5% stake. Arghakhanchi Cement was originally known as Dynasty Cement.

Colombia: Cementos San Marcos has ordered a vertical roller mill to grind coal from Loesche. The order follows a previous purchase of a LM 35.2+2 mill to grind cement. The new coal mill will replace an existing smaller mill and reuse its foundation. The classifier and the plant ducting equipment will also be part of the contract. The cement plant was designed as a two-phase project to start a conservative market entry with the aim to more than double production capacity to meet market needs within a short period of time. The new coal mill fits into phase two of this progression.
