In the research project, infrared cameras are used to record the surface temperature of the clinker bed in the clinker cooler. Together with calculated enthalpy flows, this allows control room personnel to identify the operating condition of the cooler. This is used in operational tests to optimise the heat transfer in the clinker cooler by controlling the drive system and adjusting the cooling air distribution.

Separate ultra-fine grinding of cement - Energy-efficient grinding meets optimised cement and concrete properties. Today, future-oriented cements can already be produced more sustainably and efficiently by using various components of different finenesses.

EN 197-5 defined the clinker-efficient cements CEM II/C and CEM VI. Technical approvals for the application of CEM II/C cements have been issued. For a widespread application, it is important that all parties involved develop confidence in the new products. With new findings on fresh concrete properties, hardening behaviour and durability two research projects of the VDZ Concrete Technology Department will provide an important basis for application of these cements in concrete for the construction industry.

With us, you can expand your knowledge around the production of cement and lime, as well as in the area of concrete technology. As a competent partner, we have been offering our customers individual qualification solutions since 2010. In addition to German-language online courses, we also offer English- and Russian-language courses and other services.

With the decarbonisation of cement production and the expected reduction in blastfurnace slag and fly ash quantities, unburned limestone, calcined clays, and recycled fines will gain in importance as cement main constituents. The focus will be on new, clinker-effcient cement types such as CEM II/C and CEM VI cements, whose performance allows a wide range of applications in practice. This seminar provides an overview of the current state of development and standardisation of new cements. The possibilities and limits for practical implementation will be presented.

This course covers all the relevant aspects concerning the use of alternative fuels in cement plants. Starting with the main political drivers such as the circular economy and the European waste fuel strategy, the training will give a detailed view of the current state-of-the-art-situation with regard to the use of alternative fuels in the EU. In this context, pre-treatment and suitable quality control of alternative fuels will be also explained and presented. A main focus will be given to the drivers and barriers of the use of alternative fuels within the burning process. Relevant aspects will be explained and discussed with the participants. Finally, technical feasibilities, case studies and possible optimisation potential will be part of the training course.

Climate protection and digitisation are key challenges for the cement industry: More than 600 representatives from the international cement industry and associated suppliers, as well as from scientific and research institutes around the world, gathered at the International VDZ Congress 2018 in Duesseldorf at the end of September. Steeped in tradition, the VDZ Congress is one of the world's most important events in the industry. The 40 talks held at this year's congress focused on particularly pressing topics such as climate protection and digitisation. The participants also discussed current technical challenges and the general situation with regard to cement production. A further highlight was an evening ceremony at which the winners of the VDZ Industrial Safety Prize 2017 received their awards.
