KÇS Kipaş Çimento orders Pyrorotor from KHD Humboldt Wedag
17 August 2022Turkey: KÇS Kipaş Çimento has placed an order with KHD Humboldt Wedag for a Pyrorotor for its Kahramanmaraş cement plant. The supplier says that the equipment will enable the plant's calciner to achieve an alternative fuel (AF) substitution rate of 90%. It will additionally restrict NOx emissions to 800mg/Nm3. After a short shutdown for assemblage of gas duct connections, KHD expects to commission the upgraded system in mid-to-late 2023.
The company says that the KÇS Kipaş Çimento contract represents its 11th Pyrorotor order globally and the first in Turkey.
New clinker production lines in the US
27 July 2022Congratulations are due to the National Cement Company of Alabama and Vicat for the inauguration of the new production line at the Ragland cement plant in Alabama. The event took place on 21 July 2022.
The US$300m project was originally announced in late 2019. It then took two years to build with construction starting in January 2020. Key features include a raw vertical grinding mill, a new roller mill, a five stage preheater tower, an automatic clay storage system, a 78m tall homogenisation silo, an alternative fuels storage area for tyre-derived fuel, sawdust and wood chips, a laboratory and a new control room. The new kiln was previously reported to have a clinker production capacity of 5000t/day and it will add up to 2Mt/yr of cement production capacity to the plant. ThyssenKrupp signed up as the principal equipment supplier in 2019 and H&M was the main contractor. The production line is expected to reduce energy consumption by one third. Further change is scheduled with a switch to production of Portland limestone cement (PLC) from Ordinary Portland cement (OPC) by the start of 2023.
Vicat has repeatedly noted its affection for the plant as it was the first cement plant the group purchased outside of France, back in 1974. Indeed, Vicat’s group chair and chief executive officer Guy Sidos personally managed the Ragland plant in 2001. However, rather more prosaic reasons may also have been behind the decision to expand Ragland. According to United States Geological Survey (USGS) data, Alabama, Kentucky and Tennessee’s cement shipments grew by nearly 5% year-on-year to 7.1Mt in 2019 from 6.8Mt in 2018. Shipments are up by 3% year-on-year to 2.5Mt in the first four months of 2022 and the three states were the fifth largest region in the US for cement shipments in April 2022. A shortage of cement was also reported in Alabama in April 2022.
The other big US-based cement plant expansion is Lehigh Hanson’s US$600m upgrade to its Mitchell plant in Indiana. It also celebrated a milestone this week with a ‘topping out’ ceremony to mark the placement of the final section of steel for the stack. Another recent achievement here was the completion of a 169,000t storage dome supplied by Dome Technologies. The supplier says that the 67m diameter and 48m tall dome is the second largest clinker storage facility in Europe and North America, after one it previous built in Romania in 2008.
The Mitchell K4 project was announced in mid-2018 and then ground breaking began in late 2019. However, the start of the coronavirus pandemic delayed construction in early 2020 before it restarted in September 2020. The revised commissioning date was then moved back about half a year to early 2023. The key part of this project is that it will replace the plant’s three current kilns with just one. The new production line will increase the site’s production capacity, reduce energy usage and decrease CO2 emissions per tonne of cement. It was reported by local press back in 2018 that the project would increase the plant’s cement production capacity to 2.8Mt/yr. The project has been linked to supplier KHD with CCC Group as the contractor.
It’s fascinating to see two major new upgrades to cement plants emerging in a mature market like the US and during an unprecedented event like the emergence of coronavirus. No doubt compelling tales will emerge of how both teams coped with managing nine-figure capital expansion projects as a global public health emergency unfolded. The US market has been on a roll in recent years, despite all the uncertainty in the world, and so far it doesn’t seem to be slowing down. With luck both of the projects feature above have timed their opening right.

Thailand: Germany-based KHD Humboldt Wedag has reported the successful commissioning of a new Comflex grinding line at Siam City Cement’s Plant 1 in Saraburi. The line replaces two ball mill circuits, maintaining a production capacity of 350t/hr with a 40% lower energy consumption. The Comflex comprises a roller press, RPM18–200/180 static coarse material separator, VS620 static fine material separator, LS8600 system fan, HKSK 236/346 and four product separation cyclones. KHD says that Siam City Cement awarded it the engineering, procurement and construction (EPC) contract because of the system’s low specific power consumption of 13.36kWh/t, compared to over 21kWh/t in the previous system.
News roundup
18 March 2020With events moving fast in Europe with regard to the on-going health crisis, here are a few threads to consider from the cement industry news this week.
Firstly, there have been two solar power stories over the last week in North America. Grupo Argos said that it had installed a 10.6MW solar power plant at Cementos Argos’ Piedras Azules cement plant in Comayagua. Then US-based Alamo Cement Company was reported to have signed a contract with Renergetica to build a solar power plant at its integrated plant in San Antonio, Texas. Global Cement has looked at this topic on and off over the years from the steady addition of photovoltaic (PV) solar plants around the world to supply electricity to cement plants to more ambitious plans such as research into using concentrated solar power to start powering creating clinker directly. These two latest PV stories follow projects in El Salvador and Cyprus so far this year. We’re not going to comment now on the overall progress the cement industry is making towards moving away from fossil fuels but the general trend is encouraging.
Next, there are on-going investments and upgrade projects being announced. Germany’s KHD revealed on 17 March 2020 that is building a new raw mill and pyroprocessing line for an ACC plant in India. FCT combustion recently announced that it has won a deal to supply Titan Cement in the US with an upgrade to a kiln line to natural gas. Buzzi Unicem’s SLK Cement in Russia has agreed to co-process solid municipal waste at its Sukholozhskcement plant. South Africa’s PPC has invested in a pneumatic offloading facility and a silo for its George Depot cement terminal in the Western Cape. These will have likely been agreed before the global coronavirus outbreak but they are reminders that some level of capital expenditure by cement companies is happening.
In China the Ministry of Industry and Information Technology (MIIT) said this week that the domestic cement sector’s net profit grew by 20% year-on-year to US$26.6bn in 2019. With this in mind the first quarter results for 2020 from cement producers in China will make essential reading for producers from elsewhere around the world wondering what to expect. However, a recent interview with the president of Huaxin Cement, a company based in Hubei province at the epicentre of the outbreak, revealed that despite the short term economic disruption from the quarantine the company was expecting a rapid economic rebound after April 2020 provided that there is a suitable government stewardship. He also mentioned the key role the company was playing in disposing of clinical waste. As such it was hoping for tax breaks to support continuing incineration and the advancement of co-processing in general.
Finally, also on the health crisis, many cement industry events have been cancelled or postponed as work practices change including those organised by Global Cement. We’re taking our events online in the short term as virtual conferences with opportunities for information exchange and networking. We encourage as many of you as possible to register.
