Bangladesh: Loesche has received an order to supply a 56.3+3 CS type vertical roller mill for the Aman Group’s Haria 2 cement plant at Narayangonj near Dhaka. The contractor for this order is the China National Heavy Machinery Corporation (CHMC). It follows a previous order by the Aman Group for a Loesche LM 56.3+3 CS mill that was supplied in 2014 for the Haria 1 line. The new mill was supplied in late 2016.

The roller mill for the Haria 2 line has a production capacity of 240t/hour for Portland and composite cement clinker with a fineness of 3200 Blaine or 175t/hour of ground-granulated blast-furnace slag (GGBFS) with a fineness of 4500 Blaine. It has a drive power of 5300kW. In addition to the mill, the scope of supply also specifies additional technical equipment for the grinding plant including a rotary feed, a two-way chute, a metal detector and a permanent magnet drum separator.

Nigeria: Loesche has released details on its order for the United Cement Company of Nigeria (Unicem) cement plant at Mfamosing, near Calabar in Cross River State, which was commissioned in September 2016. The order was for two vertical roller mills (VRM): one type LM 60.4 for grinding cement raw material and one LM 70.4+4 CS, the biggest Loesche VRM built for grinding cement clinker.

Loesche worked with Renk to develop the Compact Planetary Electrical (COPE) drive due to the high power requirements of the LM 70.4+4 CS mill. This mill was designed for a capacity of more than 370t/hr to a fineness of 4700 Blaine that required a drive system that could power it up to 8800kW. So the COPE system was designed for mill drive powers ranging from 4000 – 15,000kW. The COPE gearbox is also equipped with eight individual drive units, which are each designed for a capacity of 8800kW, allowing for redundancy in case of unit failure.

Other notable highlights of the installation that Loesche have highlighted include the equal size as standard drive units for VRMs that allow for the exchange of conventional gearboxes with the setup. The installation is also the first usage of an eight-drive unit in a VRM gearbox and the first time a multiple drive in a VRM can operate with or without a variable frequency drive.

Delivery of the order started in October 2015. First production of cement on the new production line began in September 2016. The new line increased the plant’s cement production capacity to over 5.5Mt/yr from 2.5Mt/yr. It was built by China’s CBMI Construction.

Thailand: Siam Cement has ordered a LM 56.3+3 CS vertical roller mill from Loesche for its cement plant in Kaeng Khoi. The mill will produce medium-fine cement qualities and is designed for grinding clinker, gypsum and limestone. The cement producer previously ordered a LM 56.3+3 CS mill from Loesche for its Ta Luang cement plant in 2014.

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.

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.

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.

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.
