Energy-efficient automation in construction chemistry

Summary: At their development center ARDEX continuously research and work on new ideas and innovative product systems, within the framework of precisely controlled research processes. With a new plant from the AZO GmbH + Co. KG, the continuous improvement and optimization of the products as well as the manufacture of newly developed products should be made possible in Witten. A high degree of automation and metering of small quantities as accurately as possible were only a few of the requirements for plant technology to achieve the long-term goals of ARDEX. After a detailed project study, ARDEX decided in favour of a vertical tower concept according to which the raw materials are pneumatically conveyed to the top and then proportioned and weighed in free fall and fed to the mixing process and the following filling processes.
