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 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 ...
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...
Rail freight forward thinking
With a steep reduction in UK train passenger numbers and a thinned-out passenger train timetable due to COVID-19, freight and logistics firm Freightliner has been exploring new types of services to improve efficiency...
The quarry of tomorrow
Are full-scale digital solutions for small- to medium-sized mining operations talk of the future or have they already become a reality? The OEM agnostic smartQuarry suite by German start-up firm talpasolutions uses a...
Versatile AF burning
The KHD PYROROTOR ® is a rotary combustion reactor that processes waste materials with inferior burning properties as alternative fuels in the cement production process. With seven industry installations to date, th...
Vicat’s SeRaMCo contribution
France-based multinational Vicat group has been contributing to the European SeRaMCo (Secondary Raw Materials for Concrete Precast Products) project, aimed at reducing the carbon footprint of the construction sector ...
FLSmidth’s smart moves
With the launch of ECS/ProcessExpert ® V8.5, FLSmidth brings artificial intelligence (AI) technologies to advanced process control. But what exactly does this mean for cement producers? Javier Pigazo Merino, FLSmidt...
JK White Cement’s journey of continual improvement
Producing white clinker and white cement requires the right raw materials, proper homogenisation, the right fuel and optimal plant process conditions. The JK White Cement plant in Gotan, India, is committed to mainta...
Informed process optimisation
Successfully operating cement kilns with high rates of alternative fuel is essential in the transition to sustainable cement production. To ensure stable process conditions, detailed monitoring is necessary. Infrared...
Stepping up cooler efficiency
Tianjin Cement Industry Design and Research Institute Co’s new fourth-generation cooler, called the ‘Sinowalk’, includes key features such as high heat recovery efficiency, stable mechanical performance and intellige...
Dealing with dust
With dust chemistry varying between direct operation when the raw mill is out of action and indirect operation when the raw mill is running, finding a destination for baghouse dust while maintaining a homogenous kiln...
