Smart conveying
To get the maximum out of maintenance, proactive and predictive approaches have proven to increase the overall efficiency of plant equipment. The PREMAS® 4.0 predictive maintenance solution, developed by AUMUND for conveying equipment, combines both these strategies. The data-based system enables a cement plant to plan, take timely action and prevent potential issues before operations are impa...
Inline and offline oil filtration
Proper 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 oi...
Changing colour
Brown 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 lab...
VRM audits and optimisation
The 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 pro...
Radiometry: advancing cement process control
In 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 lev...
The cement industry’s energy challenge
With 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 e...
Sample preparation meets digitisation
Process 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 ...
Measuring systems for CCUS
Following 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 red...
The future of process control
The 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 prod...
Keeping Austria’s air clean
Rather 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 p...
Optimised fuel metering for Solnhofer Portland Zement
As 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 ...
Clay calcination – accelerating cement’s green transition
With the cement industry’s goal of working towards saving the planet, FLSmidth proposes a simple switch: replace 30 per cent of clinker with calcined clay for up to a 40 per cent reduction in CO 2 emissions. In this...
Producing boron cement
The creation of low-energy belite clinker is a specific area of research that aims to reduce CO 2 emissions from the cement manufacturing process. Boron minerals, of which Turkey has 73 per cent of the world’s reser...
Retznei’s alternative transport
For economical and sustainable operations, Lafarge Zementwerke GmbH’s Retznei plant in Austria relies on alternative fuels and raw materials to ignite the new calciner. To transport, store and dose kiln-ready materia...
The potential of activated clays in cement
One of the pathways to a more sustainable cement industry is the reduction of the clinker factor in cement. The use of thermally-activated clays not only reduces the clinker content but also lowers CO 2 emissions as...
Staged combustion deNOx technology for calciners
Under increasingly stringent pollutant emission standards, deNO x systems are widely used in Chinese cement production. As the calciner is relatively flexible and adjustable in its design, it is a key piece in the p...
