Kunda Nordic Tsement to spend Euro2.2m on upgrades
05 June 2018Estonia: Kunda Nordic Tsement plans to spend Euro2.2m on upgrades to its operations. The investment will be used for emission improvements, updating its plant’s power distribution system, starting to use clinker dust in cement grinding and dredging the port of Kunda, according to the Virumaa Teataja newspaper.
The subsidiary of Germany’s HeidelbergCement increased its output of clinker and cement by 20% and 60% respectively in 2017. Its plant relaunched its second kiln in 2017 but this increased its CO2 emissions. It produced 1081kg of CO2 per ton of clinker compared to the European target of 766kg. The plant operates two wet process kilns but it plans to switch to a dry production process in the future as this would help it reduce its emissions.
HeidelbergCement holds a 75% stake in the company with the rest belonging to Ireland’s CRH.
South Korea: Ssangyong Cement plans to install a waste heat recovery (WHR) unit at its Donghae plant in Gangwon. The upgrade will be operational by August 2018, according to the Maeil Business Newspaper. The new unit is expected to save the cement producer about 33% of its electricity costs or US$24m/yr.
The investment is the largest that the cement producer’s owner Hahn & Company has approved since it took control. The WHR will work with an energy storage system (ESS) that was installed in March 2018. The ESS saves power consumption by storing energy during the night and then using it during the day. The 22MWhr storage system is power by powered by 2880 batteries. The company said that it would save it at least US$2.4m/yr.
Ssangyong Cement’s Donghae plant is one of the largest in the world with a cement production capacity of 11.2Mt/yr across seven production lines. It occupies an areas of 11.3MM2.
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.
Bestway Cement orders four mills from Loesche
29 May 2018Pakistan: 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.
