Egypt: Misr Beni Suef Cement has delayed the installation of a coal mill at its Beni Suef plant to the third quarter of 2017. Farouk Mostafa, managing director of the company, said that the delay has been caused by a shortage of US Dollars needed to pay to import the mill and its spare parts and general currency variations with the Egyptian Pound that has raised prices, according to Daily News Egypt. The mill was originally planned for December 2016.

Georgia: Gebr Pfeiffer has received an order to supply a mill for HeidelbergCement Group’s Kaspi plant. The vertical roller mill will be used in a new 3000t/day kiln line at the site. The order was placed through the China’s Sinoma Chengdu in November 2016.

The type MPS 4000 B mill, equipped with a SLS 3750 B type classifier, has been designed for a capacity of 270t/hr of raw meal. The mill will be delivered with an enlarged housing to allow the raw material with a moisture of up to 10% to be dried almost exclusively with the available preheater gases.

Commissioning of the plant is scheduled for 2018.

Iran: Gebr Pfeiffer has released information about a MVR 4250 R-4 raw mill that will be installed at Biarjaimand Cement Company. The raw mill, with an installed drive power of 3000kW, is designed to grind 280t/hr of cement raw material to a product fineness of ≤ 12 % R 90µm. The contract was awarded in September 2016 and the order was placed through the Chinese general contractor Beijing Kaysun Trading, a subsidiary of CATIC based in Beijing. Gebr Pfeiffer staff will also supervise erection and commissioning. The delivery of the equipment is scheduled to start in the second half of 2017.

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.

Austria: A Tec has commissioned a Rocket Mill RM 2.50 for ASA at its waste treatment plant in Wiener Neustadt. The mill has a capacity of 7 – 40t/hr and is equipped with two grinding chambers, which can be independently loaded. Each one has a main drive with 315kW. Due to the grinding technology, it also has an additional drying effect of approximately 10%. The mill is designed to produce refuse-derived fuels (RDF) with an output size of 5 - 80mm from pre-sorted and shredded household and commercial waste. It was principally built at A Tec’s plant in Eberstein.

Turkey: Korfez Eng. has signed an order with a cement producer to supply a new shell lining system. The scope of the order is a complete replacement of a wear shell lining for a single-compartment mill with an effective grinding length of 4m and 14.5m, the mill discharge and complete new manhole covers in modified execution. The complete lining is of a wave profile type WAVE 35/50 in a highly wear-resistant steel castings with 27% chromium content. The complete contract scope will be completed and delivered within a month and a half.

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%. This will achieve a total guaranteed production capacity of 150t/hour for Pozzolanic Portland Cement at 3600 Blaine. The upgraded circuit is to be commissioned by 31 March 2017.

Djibouti: Gulf Agency Services has shipped a cement ball mill and its components to Djibouti, according to Breakbulk. The mill was shipped from Jebel Ali, UAE to the Port of Djibouti. Gulf Agency Services is an associate company of Maritime Transport International that is base in Djibouti.
