60% of the electrical energy comsumed in cement production is used for comminution. In order to reduce this amount, VDZ is engaged in researching new ways of comminution and optimising existing grinding plants. You can find more information in the following video.
Mechanical process technology
In the field of mechanical process engineering, we offer a wide range of services, from the characterisation of solids in powder form and the performance of complex grinding and classification trials, right through to the optimisation of industrial plants. Above and beyond this, our interdisciplinary teams of experts can advise you on how to deal with technical problems in existing installations and on the planning of new plants.
Less energy use through optimisation and new ways of comminution
Main focus of our services
Our laboratory staff and technicians have many years of experience of working with the often sensitive measurement procedures in mechanical process technology. The key analytical procedures are accredited and regularly monitored by round robin tests and internal quality checks. Our mechanical laboratory thus has both the ability and the applicable experience to be able to perform the entire spectrum of necessary analytical work, together with interpretation of the results. Our experienced specialists regularly implement optimisation projects for industrial grinding plants in the cement industry and associated branches throughout the world and are fully familiar with the requirements of industrial practice. Within the framework of individual projects and in the course of implementing publicly funded research projects, we systematically work to improve our understanding of process technology and on the constant advancement of our methods. This produces a symbiosis of research and practice which is unique in its form. Our knowledgeable experts would be pleased to offer you their advice, from sampling and the production of an analysis schedule, right through to interpretation and implementation of the results to optimise the installation.
