Uzbekistan: Bekabadcement is carrying out a 'large-scale' upgrade to its 0.7Mt/yr Bekabadcement plant in Tashkent Region. The producer said that the upgrade involves a 20% capacity expansion of the plant's production line to 2500t/day. Austria-based Unitherm CemCon supplied burners for the upgraded line, while China-based Beijing Triumph International Engineering supplied heat exchanger components and a KC 4.1-0955 cooler. The upgrade also involves the installation of new kiln lining, and will transition the plant's cement production from wet to dry process. Germany-based Christian Pfeiffer previously upgraded the Bekabad cement plant's grinding unit in April 2023.

General director Vasily Korobkin "We see that (parent company) United Cement Group (UCG) is interested in the modernisation and development of the enterprise. The group adheres to international standards, so all plans for the development of the plant are built accordingly." He concluded "We expect to become a modern and successful enterprise in Uzbekistan which is capable of becoming a major player in the cement industry of Central Asia.”

Interesting news from Holcim Mexico this week with the announcement that it is planning to invest US$40m towards building a 0.7Mt/yr grinding plant in the state of Yucátan. The unit will be supplied with clinker from Holcim Mexico’s Macuspana and Orizaba integrated cement plants. This follows the news in August 2018 that Elementia’s cement company, Cementos Fortaleza, had started to build a new 0.25Mt/yr grinding plant at Merida in Yucatan. That project has a budget of US$30m.

These two projects offer a contrast to comments made by the head of Cemex Mexico, Ricardo Naya Barba, who was lamenting the state of the market to local press at the start of the month. He said that sales volumes of cement, concrete and aggregates had fallen by 12 – 15% in the first seven months of 2019. He blamed the decline partly on falling national infrastructure investment. This marked a slight improvement on Cemex’s Mexican results for the first of 2019 where sales, sales volumes and earnings were all down. At this time as well as slowing infrastructure projects the situation was also attributed to a residential sector hit by the slower-than anticipated start of the new programs.

Elementia’s Mexican cement business, Cementos Fortaleza, reported a similar picture in the second quarter of 2019. Its net sales fell by 6% year-on-year to US65.4m from US$69.7m. This was attributed to a market contraction affecting all of Elementia’s businesses in the country, as well as the redefinition of its core products for the Building Systems business unit. Earnings fell also and this was further attributed to mounting energy and freight costs. Cementos Moctezuma faced many of the same issues. Its cement sales fell by 13% to US$147m in the second quarter of 2019. It is expecting a similar picture for the remainder of the year.

Data from the National Institute of Statistics and Geography (INEGI) shows that the value of cement sales in Mexico fell by 7% year-on-year to US$1.21bn in the first quarter of 2019 from US$1.30bn in the same period in 2018. Cement sales volumes fell by 8.2% to 10.9Mt from 11.9Mt. This was the lowest figure since 2014.

The one larger Mexican cement producer that doesn’t seem to have been overly troubled so far in 2019 is Grupo Cementos de Chihuahua (GCC). Earlier in the year the company was considered to be the Mexican cement producer most at risk from potential US tariffs due to higher reliance on exports than its competitors. Yet Mexico’s National Chamber of Cement (CANACEM) publicly said that that it didn’t consider US tariffs a significant barrier to the local industry. GCC reported growing net sales and cement sales volumes in the second quarter of 2019 due to industrial warehouse construction, mining projects and middle-income housing at the northern cities.

Two new grinding plants in a particular region of Mexico don’t necessarily reflect the state of the country’s industry as a whole. Yucatan may suit the grinding model due to a lack of raw materials or strong shipping links. The region may also be defying the gloomy national state of affairs in the construction sector. Alternatively, producers may be chasing low-cost and low-risk expansion plans in a tough market. The grinding model wins out over the clinker producing one in this scenario. In the wider picture in August 2019 Cemento Cruz Azul ordered two petcoke grinding mills from Germany’s Loesche and Austria’s Unitherm Cemcon said it had been awarded the supply of an MAS DT burner to an unnamed cement plant. These suggest that, although the sector may be having a bad year so far, things are expected to get better.

Kyrgyzstan: Kant Cement has upgraded its packing equipment at its integrated plant. Russia’s Vselug supplied a Turbo K8 filling machine and Germany’s Berg provided compressors, according to Cement and its Applications magazine. The company plans to sell at 60% of its products in 25kg and 50kg following the upgrade.

The plant has also been installing general upgrades at the site, including a new combination burner from Austria’s Unitherm Cemcon in 2018. It is also planning to upgrade an electrical distribution substation by the end of 2019 to reduce interuptions to production.

Mexico: Austria’s Unitherm Cemcon has been awarded the supply of an MAS DT burner to an unnamed cement plant in Mexico. The burner is designed for coal, natural gas and liquid secondary fuel operation. To optimise the maintenance work, the burner is equipped with a divisible jacket tube. A satellite burner, with the supplier’s adjustment system, will be mounted on top of the main burner to improve solid secondary fuel utilisation.

South Korea/Thailand: Austria’s Unitherm Cemcon has commissioned a MAS kiln burner at a cement plant in South Korea. The order was issued in late 2018 for three MAS burners. The first burner was delivered in February 2019 and the other two in March 2019. In May 2019 Unitherm Cemcon says it supported the commissioning of the first burner.

The scope of supply included two 43MW MAS/4/KO SO type burners for coal and heavy oil and one 87MW MAS/7/KO SO.X type rotary kiln burner for coal, heavy oil and solid secondary fuels. All three burners have been executed with a divisible burner jacket tube. One MAS/7/KO.SO.X is already successfully operating in another line, firing up to 6t/hr of coal and around 10t/hr of solid secondary fuel.

The burner manufacturer has also been awarded a contract to supply a hot gas generator for a plant in Thailand. The scope of supply includes: engineering and manufacturing drawings for the hot gas generator combustion chamber; a combined 45MW oil and coal burner; a primary air fan; a gas electric pilot burner; a flame monitoring device; and an oil valve train with burner management system.

Austria: Unitherm Cemcon has launched the MAS DT rotary kiln burner, a new product in its Mono Airduct System (MAS) product line. The new burner is already in operation at six cement plants in Austria, Germany and France.

The new design uses a more efficient primary air injection, resulting in higher effective momentum and optimised combustion. Placing the adjustable primary air openings directly at the burner tip leads to unobstructed injection of the air jets into the kiln. With minimum losses at the air nozzles, the entrainment of secondary air is improved by approximately 15%.

The new primary air system, with discs instead of flexible hoses, requires less space inside the primary air channel. Therefore, the burner is smaller in diameter and lighter in weight, which reduces investment costs. Unitherm Cemcon says that the cooling of the outer jacket tube with the MAS system (hose and disc design) is superior to that of other rotary kiln burners, as 100% of the primary air is used for cooling. With the new disc system, the cooling of the burner tip is improved even further. The producer added that all new MAS DT burners showed improved lifetime of the refractory lining at the burner. On average the refractory lifetime is extended by approximately 20%.

Trinidad: Austria’s Unitherm Cemcon has been awarded the contract for a rotary kiln burner for kiln 3 at Trinidad Cement’s 1230t/day plant. The burner for the wet process unit will be designed for natural gas and liquid alternative fuel. No value for the order has been disclosed.

The scope of supply includes: one MAS/5/EGSO model rotary kiln burner; a flame monitoring device for the rotary kiln burner; a gas electric ignition burner with control box and touch screen; kiln burner trolley engineering and main components for local manufacturing; primary air fan with sound protection housing; and an emergency cooling air fan.

Other recent projects from Unitherm Cemcon include the commissioning of a firing system for BUA Cement’s new plant in Edo State, Nigeria and delivery of firing equipment for a project in Argentina in late 2018.
