Request publicationThe 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.
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.
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.
The cement industry provides excellent job opportunities for young engineers and scientists. Training schemes introduce these new employees to cement technology, taking their different professional backgrounds into account. This online course provides a one-week in-depth training session which covers all relevant aspects of cement technology including chemistry, mineralogy and environmental aspects. Quality control as well as cement performance in mortar and concrete will also be covered.
This Course covers all topics concerning the high efficiency and availability of a cement plant’s key machinery. Measurement of rotary kilns and ball mills as well as independent expertise in mechanical maintenance and inspections are also among the major aspects. Besides, we provide an extensive know-how transfer on high quality refractory kiln brick lining materials and installation including their relation to mechanical failure.
The SIMULEX® cement plant simulator for training plant supervisors, foremen, production personnel, control room operators and young engineers was developed by KHD Humboldt Wedag AG in cooperation with VDZ. For over ten years VDZ has been using the simulator within the framework of training courses and has been continually supporting the further development of the system with practical input from the industry. As a result, the simulator provides a realistic reconstruction of a production plant with a state-of-the-art supervisory control and data acquisition system (SCADA).
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.
