Research projects
CO₂ capture in cement production using shaft calciner in combination with a rotary kiln
As plans are progressing for the CCUS infrastructure for transporting, storing and using CO₂, it is becoming increasingly clear that the separated CO₂ must be very pure in order to be used or stored. CC technologies are currently being planned with considerable engineering effort and electricity consumption for gas cleaning systems to separate unwanted accompanying substances. This is where this project comes in. It aims to investigate an innovative concept that could significantly reduce this effort.
Behaviour of trace elements in modern rotary kiln systems - effects on emissions, CO₂ separation systems and the product
Precise material balances and up-to-date transfer factors are essential for evaluating trace element emissions in cement clinker production. Outdated data makes it difficult to use modern, CO₂-neutral raw materials and fuels. The project aims to update the transfer factors to support industry, the environment and climate protection.
Influence of the grinding system and the internal particle size distribution on the performance of cements with calcined clays
In the IGF research project 23643 N, relationships between the particle size distribution of different cement compounds (clinker, calcined clays and limestone powder), and their reactivity and influences on cement performance are being systematically investigated.
Training
E-learning
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.
Crash course process control
As a participant in this course, you will receive a possibility to get acquainted with the state-of-the-art supervisory control and data acquisition system (SCADA) thanks to a realistic reconstruction of a production plant provided by SIMULEX®. 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.
Grinding technology in cement production
Raw material and cement grinding are the first and the last major process steps during cement production. The energy demand of these two processes amounts to up to ~70% of the electrical energy used in a cement plant. For you as participant, this training will help to obtain a better understanding of the comminution processes as well as the equipment used for grinding. The knowledge acquired in this online seminar will deliver a solid basis for assessing and evaluating the optimisation potential for grinding processes and the ground product.
Events
VDZ Congress 2024
The 9ᵗʰ International VDZ Congress took place in Düsseldorf on 6 – 8 November 2024. The VDZ Congress is the international scientific forum for the cement industry and its suppliers. Delegates from all over the world discuss the latest developments concerning the transformation of the industry on its way towards climate neutrality.
