What is to be done when there is no empirical data for the production conditions of using a mixer in advance? And what to do furthermore if the construction site of the mixer is difficult to access? These were the initial conditions that BHS-Sonthofen GmbH, Sonthofen/Germany, had to contend with as part of the ARGE ETS Konrad mine
project in Salzgitter-Bleckenstedt/Germany. It had to design a BHS twin-shaft batch mixer and deliver a custom-designed mixing plant.
