  • Fine-Milling to Create Nanoparticles from Large Substrates

    25/02/2017· Planetary ball mills were previously the only method used for the production of particles under 1 µm with mills from the Fritsch product range, and because of this, the company developed the Planetary Mono Mill PULVERISETTE 6 classic line. An appropriate test situation was the use of this line to grind quartz sand as the preferred "model

  • Mill (grinding) Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

However, most of the measurements to characterize the rheology for slurries were performed for slurries with a maximum solids concentration of 30% by volume. This is most probably influenced by the limitations imposed by the equipment
