Australia: The Kandos Bicentennial Industrial Museum has moved a ball mill from the former Cement Australia Kandos plant to its collection. The aim is to make the mill the centre of the museum's external collection, according to local press.

"We were very lucky to be offered the ball mill by Cement Australia," said Dr Buzz Sanderson, president of the Kandos Museum. "When Cement Australia decided to demolish the Kandos Cement Works, it asked us which parts we wanted to exhibit at the museum and the ball mill was one of them. There was a plan at one stage to place the ball mill down near the railway station at the entrance to town but there were just too many safety concerns."

The ball mill will be placed beside the Kandos Museum to give visitors to the museum a sense of how the machinery worked when it was in operation. The museum has had three sections cut away from the machine that will allow guests to look inside and see the inner workings of the machine.

Egypt: Misr Beni Suef Cement has reached an agreement to build a coal mill worth US$27.9m in 12 months.

"The project will be funded through self-financing and loans," said Misr Beni Suef. The company expects the project to be completed by the end of 2015. Egypt is currently struggling with blackouts and the government has cut natural gas supplies to plants, which has prompted cement companies to switch to coal.

Egypt's natural gas production has been declining for years. Production in January 2014 was down by 10% from January 2013, according to the most recent government figures. In September 2014, the Egyptian government began to allow coal imports despite environmental concerns from the high pollution coal emits.

China: Loesche GmbH has completed work on the largest slag mill in the world for Shanxi Taigang Stainless Steel Co (TISCO) in Taiyuan, China achieving a new record product rate of producing 255t/hr blast-furnace slag meal. The Loesche type LM 63.3+3 vertical mill for grinding granulated blastfurnace slag was originally ordered by the Taigang Group International Trade Co in September 2011. It started operation in March 2014.

At the TISCO steelworks the LM 63.3+3 has now been used for the pure grinding of granulated blast-furnace slag for the first time. The mill is driven by a motor with an output of 7400kW, the most powerful motor to have been installed so far by Loesche in a mill. The projected guarantee values of 255t/ hr granulated blast-furnace slag at a fineness of 4400 Blaine are reliably attained here. This is also ensured by the newly developed Loesche LDC classifier, used in the grinding plant and ideally customised to the Loesche mills.

The first Loesche LM 63.3+3 mill started production at Nallalingayapalli, India in 2009. It attains a peak value of 367t/hr ordinary portland cement at 3000 Blaine or 371t/hr portland pozzolana cement at 3400 Blaine.

Turkey: Gebr. Pfeiffer SE has received another order from Bolu Cimento Sanayii A.S., Turkey. In addition to the three MPS mills that Bolu Cimento ordered in December 2013 for the Kazan, Ankara Province plant, this order will see Gebr. Pfeiffer supply an MPS 4500 BC mill for the grinding of granulated blast furnace slag, which will be set up at Bolu Province plant. The mill will be identical to the cement mill that will be installed in Kazan.

The mill is designed to reach a throughput rate of 85t/hr of slag, ground to a product fineness of 4500 - 4750cm²/g. Gebr. Pfeiffer's scope will include the core components of the mill and classifier as well as the mill gearbox. The required drawings and parts lists for the local manufacture of housing and steel parts as well as documents for quality control will also be produced and supplied.

The delivery of the mill scheduled to start at the end of 2014 and will have been completed by early 2015.

Oman: Oman Cement has disclosed that it intends to award the contract for supply and installation of a new 150t/hr cement mill to FLSmidth. FLSmidth separately confirmed that a letter of intent had been signed by Oman Cement, although final negotiations remain to be completed. No price for the contract has been released.

Other announcements from the Oman-based cement producer include an upgrade of kiln 1 to increase production and improve pollution control. Oman cement also plans similar pollution control improvements to kiln 2 with the aid of a consultant.

Nigeria: Dangote has ordered a new vertical roller mill from Loesche for a new project, Ibese 7, at its Ibese cement plant. The mill is the 13th mill the Nigerian cement producer has ordered from Loesche for Ibese.

The order is for a LM 63.3+3 vertical roller mill for grinding clinker with components such as gypsum and limestone. The product rate of clinker type CEM I will be 310t/hr at 3200 blaine while the product rate of clinker type CEM II will be 295t/hr at 4500 blaine. The gearbox capacity for the LM 63.3+3 will be 6700kW.

In addition to the mill Loesche will deliver a LF 20 (burner dual-fuel HFO / NG) hot gas generator and all the mechanical equipment between the mill pre-bins and the product bucket elevator. Loesche will also supply all electrical equipment and automation, the building steel structure and the detail engineering of the civil works. A latest generation type LDC classifier will also be delivered by Loesche. Commissioning is scheduled for the end of April 2014.

Iraq: Sinoma (Suzhou) Construction has placed an order for an MPS 5000 B vertical roller mill for cement raw material grinding from Germany's Gebr. Pfeiffer SE. The grinding plant will be located near Sulaymaniya in northern Iraq and is the fifth MPS 5000 B in a row which will be installed there.

The vertical roller mill sold is designed for a capacity of 500t/hr at a product fineness of 10% R 80 µm and will come equipped with a 4000kW gear unit.

In addition to the supply of the core components for the grinding plant, the order includes engineering services to enable the local manufacture of mill components and the supervision of manufacture at Chinese workshops.

Liberia: HeidelbergCement has commissioned a new 0.5Mt/yr, US$14m cement mill at its cement grinding plant in Monrovia, Liberia. The German cement producer operates in Liberia through a subsidiary, Cemenco. It is the only cement producer in the country.

"The construction of the new cement mill in Liberia is in line with our strategy of modernising and expanding clinker and cement capacities in emerging markets," said Dr Bernd Scheifele, Chairman of the Managing Board of HeidelbergCement. "In Ghana, we recently increased the cement grinding capacity at our Tema cement plant and are currently building a new cement mill in Takoradi. Together with our existing plants in this region, the new mill in Liberia strengthens our coastal network in West Africa."

Investment in the new cement grinding facility in Liberia includes a two-chambered 65t/hr ball mill with high-efficiency separator, filter, fan and flow meter. The power supply of the new cement-grinding mill is provided through a 5.7MW generator plant on a rental basis.

HeidelbergCement is currently conducting investment projects in sub-Saharan Africa amounting to almost US$400m. They include expansion projects of cement capacity of about 3Mt and of clinker capacity of 1.5Mt.
