From the inventory of the quarry, a screening machine (circular vibratory screen), that had previously been used for the classification of gravel, has been made available to the Institute of Mineral Processing Machines (IAM).

The additional machine significantly increases the research possibilities in the pilot plant. The coarsely crushed material coming from the different crushers can now be directly classified on site. That, for instance, allows for a closed-loop circulation to control the particle size distribution of the crushed product.
