Get to know the Merz Technology centre
In the technical center of Merz Aufbereitungstechnik GmbH processes can be simulated on a production scale, to overcome problems with bulk solids handling in practice. Due to the stochastic nature of bulk material processes, process development and process adjustment require testing in practice. In the technical center of Merz Aufbereitungstechnik GmbH processes are simulated on a production scale. Small Tests / General Tests Product-specific behavior in the test, different parameters. Performance Tests / Confirmatory Tests By pilot-scale tests, parameters for the design such as e.g. specific throughput, current consumption, optimum rotational speeds, oscillation behavior, etc. are practically determined. The parameters determined in the pretests are confirmed or corrected.. Contract Processing Introduction of new products to the market, reproduction of processes of large quantities e.g. melting processes or mass behavior during processes, require contract processing in the technical center. On-site Test Influences such as temperatures, dampness, humidity, process-related changes of the products or process changes

Successorship at Merz Aufbereitungstechnik GmbH
"Tradition remains – innovation comes" In 1919 Karl Merz took the step to become self-employed with the Karl Merz Maschinenfabrik in the field of mechanical bulk solids processing. Thirty years later, his son Karl Heinrich Merz took over the company, expanded it and ran it until 1990. Since then, the company has been successfully managed by the third generation of Karlheinz Merz until 2019. During his time, the name was changed from Karl Merz Maschinenfabrik to Merz Aufbereitungstechnik, since the company had established itself as a sought-after specialist in the mechanical processing of bulk materials. Karlheinz Merz passed away unexpectedly on the company`s 100th birthday last year and his wife Marianne Kramer-Merz took over the company as managing director. To date, the Merz family has led the company through all ups and downs for an entire century with an excellent team of employees – a remarkable achievement. Our long history continues in 2020 under the talented leadership and successorship of Falko
