Lebanon: Intercem is building a hot gas system for a coal mill at the LafargeHolcim Chekka plant. The engineering company won the contract for the job in 2015. It is the second such contract for Intercem to build a hot gas system following a previous project at a plant in Jordan in 2013.

The new hot gas system in the coal mill plant in Chekka connects the preheater with the coal mill and comprises a hot gas duct with a length of 360m and a diameter of 900mm. The process data of the hot gas outlet of the heat exchanger are of 18,500Nm³/hour at 400°C.

The turnkey scope of supply and services for the project includes:

• Project management
• As-built-survey of the existing plant using 3D-Laser scanning
• Review of the statics of the existing steel structure and concrete construction
• Process- and detail engineering
• Supply of the mechanical equipment including steel structure
• Coordination of the locally produced components
• Supply of the electrical equipment including clarification of connections and integration into the existing control systems
• Execution of the complete foundation works
• Transport management
• Electrical and mechanical assembly of the plant
• Commissioning of the hot gas system
• Training of the operating team

In addition ducts, a cyclone, a process fan and several control dampers, compensators, the complete instrumentation and automation as well as a new recirculation duct with two control dampers at the existing vertical coal mill have been supplied.

Handover to the customer is planned for fourth quarter of 2016.

Japan: Japan's Sumitomo Osaka Cement consumed 1.41Mt of coal in financial year 2015 to March 31, 2016, down 2.7% year on year. Petroleum coke consumption in FY2015 was 0.10Mt, up 19%.

Tanzania: Charles Mwijage, the Minister for Industry, Trade and Investment, has advised local cement producers to complain to the government regarding imports of cement and a ban on imported coal. Mwijage made the comments at the inauguration of Tanga Cement’s second clinker production line, according to the Tanzania Daily News newspaper.

"We ask the government to either stop the imports or at least impose higher tariffs on imported clinkers. We are also pleading with the government to ensure clinkers on transit reach their destinations. This will remove unfair competition in the market," said Reinhardt Swart, the managing director of Tanga Cement.

The cement producer has complained to the government previously about the same issues. He added that the some of the cheap products were clinker on transit that are diverted to the local market and then sold cheaply because they are not taxed. In addition the government ban on coal imports has raised the company’s energy costs. Swart said that the company is also appealing to the government to secure more reliable electricity supplies.

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.

Nigeria: Dangote Cement intends to start mining its own coal at Ankpa, Kogi State in order to cope with gas shortages in the country. The coal will be of a high enough quality to be used without blending. Most of the cement producer’s production lines in Nigeria will have operational coal mills by September 2016. At present the company is using locally purchased coal that is blended with imported coal to ‘assure optimal quality.’

“Our investment in coal is enabling us to reduce our dependence on both oil and gas as fuel sources, thus protecting our production from disruption and improving margins,” said chief executive Onne van der Weijde.

India: Shree Cement has won its bid for a coal contract from South Eastern Coalfields Ltd (SECL) for 80,000t/yr. The cement producer will gain the supply from the New Kusmunda mine in Chhattisgarh for US$14/t. In May 2016 the company announced plans to build a 2.8Mt/yr clinker production line at its integrated cement plant in Raipur, Chhattisgarh. The US$104m line, excluding land and other infrastructure costs, is set to be completed by March 2018.

India: Prism Cement has purchased 120,000t/yr of coal from South Eastern Coalfields, a subsidiary of Coal India. The cement producer successfully bid for the fuel in a recently held auction of coal linkages for the cement industry. The company said that it has secured part of its fuel requirement for the next five years and the allocation by Coal India has been made at the floor price.

India: FLSmidth has signed a contract with Larsen & Toubro Limited for engineering, procurement and supply of equipment for a complete cement production line with a capacity of 3000t/day. The plant will be located in Ariyalur, approximately 300km south of Chennai in the Indian state of Tamil Nadu. The end client of the project is Tamil Nadu Cement Corporation Limited (TANCEM), a wholly owned undertaking of the Government of Tamil Nadu, with whom Larsen & Toubro Limited has an EPC contract. The order will be delivered over the next 16 months.

The order includes a complete range of equipment from crushing to the packing plant: ATOX® 35.0 vertical mill for raw grinding, ATOX® 20.0 vertical mill for coal grinding, Pyro Processing System with low-NOx ILC calciner, FLSmidth Cross-BarTM CB10 x 40 cooler and a UMS 5.0 x 15.0 ball mill for cement grinding. FLSmidth’s supply also includes equipment from product companies of FLSmidth, such as planetary gear units for vertical mills from FLSmidth MAAG Gear, bag filters and an electrostatic precipitator from
FLSmidth Airtech, packing plant from FLSmidth Ventomatic, a control system and plant automation from FLSmidth Automation and weighing and metering systems from FLSmidth Pfister.

Egypt: Helwan Cement has ordered a vertical roller mill from Gebr. Pfeiffer to grind coal at one of its cement plants in Egypt. Delivery of the coal mill is scheduled for the end of 2016. The order was placed by Beijing Triumph International Engineering.

The type MPS 3350 BK coal mill will have an installed gearbox power of 1050kW. It is designed to grind 80t.hr of coal to a product fineness of 12% residue on 90μm and 60t/hr of pet coke to a product fineness of 6% residue on 90μm. Gebr. Pfeifer’s personnel will also supervise erection and commissioning.

Canada: A fire broke out at a coal silo at the Lehigh Cement plant in Edmonton on 10 May 2016. Four fire fighters were sent to hospital to investigate potential carbon monoxide inhalation, according to Postmedia Breaking News. An investigation is now underway to discover the cause.

Lehigh Hanson health and safety director Gerry Sanderson said that the plant wasn't shut down or evacuated. He added that the fire had been contained and that damage to the facility appeared to be minimal.
