Inline and offline oil filtration14 December 2021, Published under Cement NewsProper oil filtration can reduce downtime and increase equipment reliability. Combining inline and offline filtration technologies can ensure optimum lubricant cleanliness, and lead to an increase in component and oil life. By Steffen D Nyman, CC Jensen and Noria Partner, Denmark. Figure 1: a cement plant has many critical systems using lubrication oil The world has an insatiable appetite for cement and concrete, so cement plants need to supply at a growing pace.

Changing colour30 November 2021, Published under Cement NewsBrown or yellow colours in the clinker core are indicative of unfavourable burning conditions such as reducing conditions in the kiln, according to specialists. At Tehran Cement Co, researchers have carried out a laboratory study into the effect of colour changes in the clinker core on the technical characteristics of cement. By Ali Akbar Kafash Bazari, Tehran Cement R&D Center, Iran, and Mohsen Tadayon, Iran Concrete Association, Iran. Figure 1: microscopic image of clinker with redu... |
VRM audits and optimisation16 November 2021, Published under Cement NewsThe increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for improvements in power consumption and performance. By Anil Kumar Popuri, National Council for Cement and Building Materials, India. Figure 1: mea... |
Radiometry: advancing cement process control15 November 2021, Published under Cement NewsIn the challenging conditions of a cement plant, traditional process control methods are not always suitable. Radiometric process control provides a non-contact and non-intrusive technique to carry out continuous level measurement, detect cyclone blockages in the preheater, measure bulk flow on the conveyor and moisture measurement. By Berthold Technologies, Germany. Figure 1: level measurement at a clinker cooler in a cement plant (blue point shows measurement location) Radiome... |
The cement industry’s energy challenge03 November 2021, Published under Cement NewsWith global cement demand expected to rise by as much as a quarter by 2050, the industry faces a range of challenges to produce in a more sustainable way. One aspect is to reduce its energy input to reflect tighter emissions legislation. By Fabio Mielli and Juliano de Goes Arantes, Rockwell Automation, USA. Green construction and decarbonisation is expected to impact the way cement plants manage their energy consumption Worldwide trends such as increasing population numbers and ... |
Sample preparation meets digitisation26 October 2021, Published under Cement NewsProcess sample analysis is increasingly important in the cement industry. The preparation of samples is key to ensure rigorous quality control of a range of materials, from raw materials to the finished products. An automatic combination of mill and press can speed up this process significantly. By Marc Bornefeld, Andre Mehling and Jan Herzog, Herzog Maschinenfabrik GmbH & Co KG, Germany. Figure 1: combined mill and press HP-MP from Herzog Sample preparation in quality control l... |
Measuring systems for CCUS25 October 2021, Published under Cement NewsFollowing the Paris climate agreement (2015), the decarbonisation of the energy and industrial sectors is becoming increasingly important. One of the most significant measures to achieve the climate targets is to reduce carbon dioxide (CO 2 ) emissions. The capture, use and storage of CO 2 is an essential part of the decarbonisation strategy and an important milestone for a low-carbon future. By Aurélie Moll and Felix Bartknecht, SICK, Germany. Figure 1: CCUS ecosystem with possible ... |
The future of process control12 October 2021, Published under Cement NewsThe global task to ensure sustainable clinker and cement production has increased the complexity of plant operations. New process control technologies, including online reactivity measurements, contribute to the production of robust clinker and cement with minimum GHG emissions. Neural networks and AI are the first choice when managing large arrays of process and quality data. A new approach is essential to overcome time gaps from process control to systematically delayed compressive strengt... |
Keeping Austria’s air clean11 October 2021, Published under Cement NewsRather than a traditional pulse-jet cleaning system, Rohrdorfer Zement opted for a state-of-the-art SWAP-based dust removal system to replace the existing kiln and raw mill electrostatic precipitator at its Gmunden plant in Austria. The system is currently under construction and scheduled to come online later this year. By CTP Team, Italy. Figure 1: from the left, the sonic wave of the SWAP cleaning system travels along the bag In 2020 Rohrdorfer Zement decided to replace the ex... |
Optimised fuel metering for Solnhofer Portland Zement05 October 2021, Published under Cement NewsAs a result of the increased use of substitute fuels at Solnhofer Portland Zement’s plant in Germany, the existing pulverised coal dosing system was increasingly reaching its limits both in terms of range and dosing accuracy. Furthermore, it was foreseeable that the fly ash used for dusting the animal meal would no longer be available. Therefore, the cement producer decided to carry out a complex conversion of its fuel dosing system. By Intercem Engineering, Germany. Figure 1: coal du... |
