Russia: Eurocement is planning a second phase of upgrades for its Kavkazcement plant in 2019. These include starting to generate its own electricity, modernising its cement grinding mills, completing a maintenance campaign and moving to solely operating rotary kilns. The first phase of the upgrade project saw the plant build a slurry pipeline, construct the building for a captive power plant and purchasing monitoring equipment.

US: France’s Fives Group has released detail about a project to upgrade the cement mill workshop at Giant Cement’s Harleyville plant in South Carolina. The contracts included the complete engineering, supply, fabrication, transport, installation and commissioning services for material handling, cement grinding and cement loading. New equipment included a clinker and additives transport circuit with a dedusting system, a classifying circuit with a FCB TSV Classifier, a new Fives TGT Filter, all gas and material connections as well as the ball mill internals revamping, a cement truck bulk loading area and a weighing station.

Engineering, offshore supplies and project management were handled by Fives FCB. Onshore supplies and all site works including civil and structural works, mechanical and electrical installations were covered by Fives Solios. Major milestones of the project included starting civil works in November 2017. Mechanical and electrical erection work ran from February to July 2018. First cement production was on 29 June 2018.

Bangladesh: Shah Cement has inaugurated the world’s largest vertical roller mill (VRM), supplied by Denmark’s FLSmidth, at its Muktarpur plant in Munshiganj. The FLSmidth OK 81-6 Mill has an 8.1m grinding table and six grinding rollers powered by two 5.8MW FLSmidth MAAG Max Drive gear systems. FLSmidth says that the mill is the largest VRM ever to be installed in a cement plant in terms of dimension, operating capacity and installed power. It was put in operation in September 2018

“We are proud to have the world’s largest vertical roller mill as part of our operations. We selected the FLSmidth OK 81-6 Mill for its exceptional efficiency and reduced power consumption – and we are expecting it to deliver as promised. As the largest single-unit grinding mill in the industry, we expect it to meet our production requirements for many years,” said Hafiz Sikander, Director of Operations, Cement Division of Shah Cement Industries.

The mill is designed to produce Ordinary Portland Cement (OPC), Pozzolana Portland Cement (PPC), Portland Slag Cement (PSC) and slag cement types. It is producing PPC at a capacity of 500t/hr at 3500 Blaine with 15% slag. In addition to the OK Mill, FLSmidth supplied the process and layout engineering, along with site advisory. The supporting equipment included FLSmidth Pfister weigh feeders, FLSmidth Airtech process bag filters, process fans and auxiliary equipment from raw material hopper discharge to process bag filter discharge.

Shah Cement Industries is the largest cement producing plant in Bangladesh, with a capacity of 8.0Mt/yr. The company is part of the Abul Khair Group, the largest business conglomerate in Bangladesh.

Egypt: South Valley Cement says it is in a dispute with China’s Sinoma CDI over an upgrade to its Beni Suef plant. The cement producer alleges that Sinoma has not met its contractual obligations on the project to build new mills. South Valley Cement says that Sinoma has liquidated letters of guarantee worth nearly US$2m, left the construction site and started arbitration proceedings. South Valley Cement is now considering its legal options. The status of the upgrade project remains unknown.

New Zealand: Fletcher Building says that its Golden Bay Cement plant in Auckland was forced stop its cement mill for four weeks in September 2018. It said it had insurance to cover this but that its earnings for its 2019 financial year are likely to be impacted by up to US$8m. Generally, the building materials producer reported that, until the end of October 2018, its business in New Zealand had been flat. In Australia it is facing ‘challenging’ conditions with growing input prices and a slowing residential sector.

Nepal: Germany’s Gebr. Pfeiffer has received an order via KHD to supply an MPS 225 BK vertical mill to grind coal for Samrat Cement. The cement company is building a new integrated production line at a plant in the Dang region.

The mill, with a drive power of 370kW, will grind 35t/hr of coal to a product fineness of 15% R 90µm. At the same time, the coal, which may have a feed moisture of up to 10%, is dried in the mill. An SLS 1800 BK integrated classifier will separate the ground coal into fine product and coarse product, with the latter being returned to the grinding zone to be again. The classifier will also allow petroleum coke to be separated to fineness degrees of <1% R 90µm.

The order was received via Gebr. Pfeiffer’s subsidiary in India. It will supply the main equipment for the mill and associated equipment for the grinding plant.

China: Guangdong Tapai has ordered two coal mills from Germany’s Loesche for its two 10,000t/day clinker production lines in Jiaoling, Meizhou in Guangdong. This is a repeat order, following an order for two LM 35.3 D coal mills that was made in 2015. The 3-roller mill grinds 50t/hr of pulverised coal to a fineness of 3% with a sieving residue of 0.08 mm. The installed power is 1200kW. The order has been placed through Loesche Shanghai and the two newly ordered coal mills are expected to be delivered in April 2019.

China: Lubao Cement has ordered three vertical roller mills from Germany’s Loesche for a new 4500t/day plant that is being built at Bei Liu in Guang Xi. The project is being handled by Sinoma (Suzhou) Construction, part of Sinoma International Engineering and China National Building Material Group (CNBM) in turn.

Loesche is supplying three mills for the project, one each for raw material, coal and clinker/slag. One four-roller mill with a capacity of 450t/hr will be used for grinding cement raw material to a fineness of 12% with a sieving residue of R 80μm. Another mill with a throughput of 200t/hr will be used for the subsequent grinding of cement clinker to a fineness of 3400 - 3600 Blaine. A large three-roller mill with a capacity of 42t/hr will be used for grinding fuel coal to a fineness of 2% and a sieving residue of R 80μm.

No value for the order has been disclosed.

Pakistan: The Flying Cement Company has ordered a vertical roller mill from Germany’s Loesche for a new 7000t/day production line in Lahore. The raw material mill will be used at Flying Cement’s plant at Mangowal, where it will grind 600t/hr. The plant is mainly used to produce Ordinary Portland Cement (OPC).

Along with the mill, the scope of supply also includes a Hurriclon system from A TEC, a member of the Loesche Group, for separating finished material from the gas flow leaving the mill.

Commissioning is expected to take place at the end of 2018.

UK: The planning department of East Lothian Council in Scotland has granted planning permission to an upgrade of Tarmac’s Dunbar cement plant. The work will include building a new cement grinding mill, a new cement storage silo and a rail loading facility. The work will also include a shed, belt conveyors pneumatic pipelines and associated works.

In its supporting statement the company said that the new cement mill was necessary to produce new grades of cement required for modern construction and the cement market. The proposed mill will replace two existing mills on the site and is intended to be more energy efficient and quieter than the existing mills. It added that the plant would benefits from rail sidings on both the south and north side of the East Coast Mainline railway line. At present trains are fed only on the south side using adjacent silos where train capacity is already fully used. Additional products are exported by road.
