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 process for NO x emissions reduction. Tianjin Cement Industry Design and Research Institute Co, Ltd has been researching NO x emissions reduction technology in cement manufacturin...
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...
Boosting mill performance
Reducing the clinker factor without compromising quality and the rising demand for high-performance cements are great challenges for the fine grinding technology used in cement plants. As part of its green cement pla...
ESP morphs into bag filter
When electrostatic precipitators are unable to meet tighter emission regulations, it can be more economical to modify them to bag filters rather than replace them with a new bag filter. Gorco SA highlights the key po...
Tripling the lifetime of lining
A Vietnamese cement plant has more than tripled the lifetime of the refractory lining in its cooler bull nose by using a precast modular lining from HASLE Refractories. Abrasion and alkali attacks have been reduced s...
The 21st-century cement plant: greener and more connected
The cement plant of the future will embrace digitisation and sustainability trends to earn a competitive advantage and build resilience. By Eleftherios Charalambous, Thomas Czigler, Ramez Haddadin, Sebastian Reiter a...
Keeping an eye on the gears
One of the greatest mechanical challenges in rotary kiln maintenance today is maintaining the efficient operation of girth gear and pinion meshing. Misalignment during production creates uneven and unstable stress co...
From WHRPG to EfW
As cement plants search for ways to reduce their carbon footprint, waste heat recovery power generation (WHRPG) systems are becoming more popular. The use of biomass also provides potential as an energy-from-waste (E...
