Resource-efficient use of sulphate-containing process dusts for sulphate optimisation using isothermal heat flow calorimetry
The research project analyses whether sulphate-rich process dusts can be used to optimise the sulphate content of cements, thereby saving anhydrite/gypsum and, in particular, improving the early strength of cements with several main constituents. Furthermore, it is to be determined whether isothermal heat flow calorimetry can be used as a fast and cost-effective investigation method for this purpose.
Increasing energy efficiency in the cement industry through training by means of virtual reality (VR)
The aim of IGF project 21619 is to develop a training simulator with which learners can independently solve typical process engineering tasks within a virtual reality (VR) environment, particularly in connection with ball mills.
Calcined Clays from mineral secondary raw materials
The aim of the research project is to investigate the suitability of previously largely unused mineral secondary raw materials from the stone and earth industry as a resource-conserving and climate-friendly main cement constituent. The use of cal-cined clays from secondary raw materials instead of conventional main cement constituents or high-quality primary clays can make an important contribution to the production of climate-friendly and resource-efficient cements.
Process Technology of Cement Production (In-Class Training)
This In-Class Training consists of two modules: "Grinding Technology and Raw Material Preparation" (Module 1) as well as "Clinker Production and Material Technology" (Module 2). Each module has a duration of one week. The course gives a deep insight into cement production technology, covering topics from quarry operation to cement grinding.
VDZ e-Learning Platform: Online Courses on Cement Production and Concrete Construction Methods
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.
Firing Alternative Fuels: Opportunities, impacts on process, optimisation and limitations (Training course 2)
VDZ offers an online course that 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. This training course provides four half-day training sessions in a webinar format. This unique format enables the employees to combine an adequate learning pace with their daily work in the plant.
International­ VDZ Congress 2018
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.
