Czech Republic: Lafarge Czech Republic plans to spend nearly Euro4m on upgrades for its Ciskovice plant. Half of this investment has been spent on rebuilding an electrostatic precipitator for the main chimney for the plant. An additional Euro1.5m will be spent on improvements to the warehouse, handling and dosing of alternative fuels for the kiln. Upgrades to improve the unit’s noise and fire protection are also scheduled.

Pakistan: Germany’s Loesche has sold four vertical roller mills (VRM) to Bestway Cement through China’s Sinoma International Engineering. The mills will be used to upgrade Bestway Cement’s Farooqia plant in the Punjab province. No expected date of commissioning or value for the order has been disclosed.

The order consists of one raw mill, one coal mill and two clinker mills. One four-roller mill VRM with a capacity of 450t/hr will be used to grind cement raw material to a fineness of 12% with sieving residue of R 90μm. Two further mills with a throughput of 170t/hr will serve for the subsequent grinding of cement clinker to a fineness of 3200 Blaine. One large modular VRM with a capacity of 40t/hr will be used in the grinding of coal to a fineness of 10% and R 90μm sieving residue.

Qatar: France’s Fives FCB has released more information about its project to build a fifth production line for Qatar National Cement at its Umm Bab plant. The new 5000t/day clinker line was ordered in April 2014 and Fives has been responsible for the supply of a complete production line from raw material preparation to cement despatch. The new line is expected to be commissioned in the first half of 2018.

The line uses natural gas for fuel. Raw material preparation includes a 1000t/hr double impact rotor crusher for limestone, clay or shale, a gamma ray analyser, two limestone storage silos of 30,000t and two shale and clay storage siloes of 10,000t. For raw meal grinding the line will use a 440t/hr FCB B-mill with a diameter of 5.6m, a length of 21.2m and a power of 6600kW. It also has a FCB TSV 7500 Classifier BF.

The 5000t/day kiln consists of a five-stage single string FCB Preheater with low pressure drop cyclones, a FCB Zero-NOx Precalciner with a diameter of 5.2m fitted with a Pillard PRECAFLAM burner, a three piers FCB rotary Kiln with a diameter of 4.8m and length of 76m, a Pillard NOVAFLAM burner for rotary kiln, a clinker grate cooler with an active area of 112m², an electrostatic precipitator for cooler dedusting, a Pillard ROTAFLAM burner as auxiliary burner and a Pillard HeatGen Systems for hot gas generation. The kiln line also includes Fives TGT UP Filters for the kiln and alkali bypass. The line has a 40,000t clinker storage silo.

Cement grinding comprises two FCB B mills with a capacity of 115t/hr. These have a diameter of 4.6m, a length of 14m and a power of 4200kW respectively. Cement grinding also includes Two Fives SONAIR Filters, two FCB TSV Classifiers and two Fives SONAIR Filters. Cement storage consists of two 20,000t silos.

Finally, cement packing and dispatch includes four truck loading systems with a capacity of 250 - 300t/yr each and one big bag loading station with a capacity of 30t/hr.

The project follows collaboration between Fives and Qatar National Cement on lines two, three and four at Umm Bab.

Venezuela: Production at FMC Venezolana’s Pertigalete plant has dropped to 30% while repair work is being unertaken on its line 6.

Philippines: Holcim Philippines plants to spend US$45m towards increasing production capacity. Its new chief executive officer John Stull told The Manila Times newspaper that the company is looking to improve efficiency at its plants to improve logistics and cut energy costs. It is also planning to hasten its equipment maintenance schedule. The cement producer set a target to increase its cement production capacity to 12Mt by 2019.

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.

Pakistan: Gharibwal Cement has started commercial operation of a 250t/hr vertical cement mill for grinding cement. It says it is the single largest cement grinding mill in the country. The cement producer operates a 2.1Mt/yr integrated plant at Ismailwal in Chakwal.

Saudi Arabia: GE has struck a deal with Saudi Cement to upgrade three GE 6B gas turbines at Saudi Cement’s Hofuf plant with its Advanced Gas Path (AGP) product. The AGP upgrade is intended to increase the combined output of the three turbines by 16.9%. The upgrade should help Saudi Cement increase power output and efficiency while reducing the need to draw power from the local power grid. No value for the deal has been disclosed.

Bangladesh: LafargeHolcim Bangladesh has replaced the belt of a 17km conveyor that transports limestone from a quarry in Meghalaya in India to its Surma cement plant in Bangladesh.
