Pakistan: DG Khan has completed the installation of its new cement grinding plant at Hub in Baluchistan. A new vertical cement grinding mill with a COPE drive has started trial operations together with cement siloes and a packing plant. Commissioning has also taken place of raw material crushing, transportation and storage units. Loesche, who supplied the mills for the project, said in 2017 that a 1050t/hr raw mill was the biggest raw material mill in the world.

Mexico: Germany’s Loesche has sold two coal or petcoke grinding mills to Cruz Azul. Both will be used on new production lines at cement plants in Hidalgo and Oaxaca respectively. No value for the deal has been disclosed.

Each mill will have a capacity of 65t/hr. Loesche will be supplying complete plant equipment, including process gas filters, mill fans, inerting units, explosion protection valves, kiln gas cyclone separators, feed screw and drag chain conveyors as well as the complete electrotechnical equipment. The scope of supply also includes engineering for steel and concrete construction.

Loesche previously delivered a LM 46.2+2 CS type mill to Cruz Azul’s Tepezalá cement plant, operated under the Cycna subsidiary, at the end of 2016.

Nigeria: Dangote Cement will use two vertical roller mills (VRM) from Germany’s Loesche for a new production line at its Obajana plant in Kogi State. The order comprises a six-roller mill for raw cement meal with a capacity of 580t/hr, the largest roller mill for raw material in the Loesche range, and a three-roller mill with a modular design featuring a drive power range of 1000kW for grinding hard coal and lignite with a throughput of up to 70t/hr.

The scope of delivery also includes a LDC classifier for the raw cement mill and a LSKS ZD classifier for the coal mill, which is characterised by individually adjustable grain size separation. The raw material mill is equipped with metal-matrix-compound (MMX) technology. The two mill gear units are equipped with state monitoring and remote access for remote monitoring. Loesche is also contributing to the design and planning of the entire plant as well as the engineering for the electrical measurement, control and regulation technology and complete automation. The delivery date is scheduled for the third quarter of 2018.

The contract partner for this project is China’s Sinoma International Engineering, which has previously installed a seven clinker and cement raw meal VRMs for the Obajana plant. The site has a cement production capacity of over 12Mt/yr and it is the largest cement plant in Sub-Saharan Africa.

Vietnam: Vicem (Vietnam Cement Corporation) Hoang Thach Cement has ordered a type LM 59.3+3 CS vertical roller mill for the Hoang Thach cement plant in Hai Duong province. The mill has a transmission power of 6200kW and it is able to grind 250t/hr of Ordinary Portland Cement (OPC) to a fineness of 3600 Blaine. Commissioning is scheduled for later in 2018.

The scope of supply also includes an external reject system, dedusting equipment, a material conveying system and multi-chamber silos with two packaging systems downstream. The system is equipped with a LOMA LF20 heater run on heavy oil, which produces around 30,000Nm³/hr of hot gas at a temperature of 450°C. In addition, Loesche is supplying the equipment for the power supply and distribution and the grinding plant control. A particular challenge of the project has been supplying new equipment for an existing plant with limited space.

India: Penna Cement has ordered a vertical roller mill from Loesche for its cement plant at Boyareddypalli in Andhra Pradesh. The mill will be equipped with four rollers to grind petcoke with a throughput capacity of 52t/hr, 3% R on 90μm. The delivery of the order to be managed by Loesche India and is scheduled to take place at the start of 2018. No value for the order has been disclosed. The mill upgrade will increase the plant’s cement production capacity to 4.6Mt/yr from 2Mt/yr.

Nepal: The German vertical roller mill (VRM) producer Loeshe GmbH has gained a new customer in Nepal. The cement division of Chaudhary Group, based in Kathmandu, has placed an order for a 25t/hr vertical roller mill for coal grinding for the 3900t/day (1.3Mt/yr) integrated cement plant that it is building in the Palpa region.

Loesche received the order though KHD, the lead bidder at the plant. The LM 26.3 D mill will be in operation during 2018 with a throughput of 50t/hr, 15% R on 90μm.

Egypt: Loesche is supplying three vertical roller mills for the Egyptian Cement plant at Sohag. The scope of delivery includes a raw material mill with a capacity of 540t/hr of cement raw meal, a cement mill with an output of 350t/hr as well as a coal mill with an output of 45t/hr. The cement mill is equipped with a COPE (Compact Planetary Electric Drive) drive.

Sinoma subsidiary, the Chinese Chengdu Design & Research Institute (CDI), is the general contractor for the project. Loesche and CDI have worked together previously on projects in Egypt including ones for El Arish Cement and Beni Suef Cement.

Sri Lanka: Insee Cement has started building a new 0.45Mt/yr cement grinding mill, supplied by Loesche, at its Ruhunu plant in Galle. Deputy Minister of Port and Shipping Nishantha Muthuhettigama and Residence Manager of Galle Sujeewa Wimalasiri attended the event, according to the Daily Financial Times newspaper. The US$14m project is scheduled for completion in mid-2018.

Loesche is supplying a jumbo-sized compact cement grinding (CSG) mill for the unit. The mill is capable of grinding clinker and granulated blast furnace slag into Portland Limestone Cement and Portland Slag Cement (PSC) with a throughput of up to 60t/hr.

Pakistan: Germany’s Loesche has been awarded a contract for four vertical roller mills by China’s Chengdu Design & Research Institute for
Pakistan’s Pioneer Cement, which is expanding its production capacity to 8000t/day in the Chenki/Khusab district in Punjab Province. The contract includes a 630t/hr Loesche mill for grinding raw meal, two Loesche finish mills, each with a capacity of 235t/hr and a 60t/hr Loesche coal mill.

Loesche Dynamic Classifiers will be used to ensure the appropriate fineness. The patented Vortex Rectifier and an optimised flow characteristic produce significantly lower energy consumption and therefore lower operating costs.

Efficient dedusting of the raw material mill is carried out using two HURRICLON® systems from Loesche’s A TEC subsidiary. This gives the advantage of reducing the total energy requirement of the plant due to the low pressure loss and high degree of separation. It also creates savings in steel construction and installation due to the significantly lower weight compared to conventional cyclone technology.

Delivery is due by the autumn of 2018.

Turkey: Germany’s Aunde has ordered four vertical roller mills from Loesche for a new cement plant being built in Soma. The order includes one 350t/hr raw material mill, one 30t/hr coal or 27t/hr petcoke mill and two 150t/hr clinker or granulated blast furnace slag mills. The scope of delivery also includes additional components such as water injection, cyclones, slide gates and rotary feeders as well as a spare parts package for the next two years.
