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... |
Clay calcination – accelerating cement’s green transition30 August 2021, Published under Cement NewsWith 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 article the company outlines why the move is not only smart and efficient but is something almost every cement manufacturer could do right now. By Steven Miller, FLSmidth, Denmark. Figure 1: FLSmidth’s clay calciner system With seven per cent of all global carbon em... |
Producing boron cement24 August 2021, Published under Cement NewsThe 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 reserves, are a possible raw material that can be used in the production of belite cements. TÜRKÇIMENTO, the Turkish cement manufacturers’ association has carried out a study into the use of colomonite boron ores to determine their suitability for the production of boron cement. By Se... |
Retznei’s alternative transport19 August 2021, Published under Cement NewsFor 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 material efficiently, the cement producer awarded BEUMER Group a contract to develop an individual single-source solution, at the core of which is a U-shaped conveyor. By BEUMER Group, Germany. Lafarge Zementwerke’s Retznei plant, Austria, relies on BEUMER’s single-source solu... |
The potential of activated clays in cement10 August 2021, Published under Cement NewsOne 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 a result of dihydroxilation instead of dicarbonation and other energy savings. By Dr Carlos Aramburo, Carlos Aramburo Consultant, Colombia; Luiz Felipe de Pinho, Dynamis, Brazil; Dr Rafael Talero, SACACH SL, Spain, and M Pilar de la Torre, Carlos Aramburo Consultant, Spain. ... |
Staged combustion deNOx technology for calciners19 July 2021, Published under Cement NewsUnder 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 manufacturing for more than two decades, and in this article charts the development of staged combustion deNO x ... |
Rail freight forward thinking14 June 2021, Published under Cement NewsWith 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 and productivity.
