    Grinding materials to a nano-scale is an important aspect of quality control and R D. AZoM speaks to Dr. Tanja Butt from RETSCH about the benefits of using High Energy Ball Mills instead of Planetary Ball Mills. Nowadays the flexibility and specific cost of manufacturing have a relevant role in the competitiveness of the companies. In our opinion the most important objective of Industry 4.0 is the realization of intermittent manufacturing at mass production s productivity and specific cost.
