Research projects


Current

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.

Current

Optimisation of energy demand and product quality during grinding in the cement industry through the use of ceramic grinding media

The aim of the IGF project 21791N is to better understand the influence of ceramic grinding media (balls) on the comminution process and the product quality during cement grinding in ball mills. The data will serve as a basis for designing and predicting the energy requirements and behaviour of grinding plants when using ceramic grinding media.

Online Course

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.

Seminar

Installation of Refractory Materials

For good lifetimes of the refractory materials in the clinker production line, a faultless installation is an important prerequisite. Even though the installation is carried out in most companies by external companies, supervision should be done by trained employees. This seminar should help the participants to be able to better evaluate the refractory installation and thereby recognise deficits at an early stage.

Seminar

Wear of Refractory Materials

The refractory lining of a cement plant is subject to wear, which can be typical to abnormal depending on the process conditions. A premature wear of the refractory lining usually results in an unexpected loss of production, which is associated with high costs. In order to be able to better assess the reasons for the wear that has occurred, the course gives an overview of the types of wear in the cement plant and their interpretation. In addition, details are shown how the wear behaviour of the refractory lining in the cement plant changes as a result of the use of alternative fuels.

Congress

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.
