  • The Emax is an entirely new type of ball mill for high energy milling. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

    Application Examples

    Alloys, Bones, Carbon Fibers, Catalysts, Cellulose, Cement Clinker, Ceramics, Chemical Products, Clay Minerals, Coal, Coke, Concrete, Fibers, Glass, Alloys, Cellulose…

    Product Advantages

    • Faster and finer grinding than any other ball mill
    • Speed of 2000 min-1 allow for ultra-fast pulverization of the sample
    • Water cooling permits continuous operation without cool down breaks
    • Temperature-controlled grinding
    • Narrow particle size distribution thanks to special jar design which improves mixing of the sample
    • Patented drive concept
    • Easy operation via touch screen, 10 SOPs storable
    • Operation with 2 grinding jars
    • Easy installation of grinding jars
    • Jars with integrated safety closure
    • Range of jar materials allow for contamination free grinding

    Function Principle

    The novel size reduction mechanism of the Emax unites the advantages of different mill types: high-frequency impact (mixer mill), intensive friction (vibratory disc mill) and controlled circular jar movements (planetary ball mill) allow for unrivaled grinding performance. This unique combination is generated by the oval shape and the movement of the grinding jars. The grinding jar supports are mounted on two discs respectively which turn in the same direction. As a result, the jars move on a circular course without changing their orientation.

    The interplay of jar geometry and movement causes strong friction between grinding balls, sample material and jar walls as well as a rapid acceleration which lets the balls impact with great force on the sample at the rounded ends of the jars. This significantly improves the mixing of the particles resulting in smaller grind sizes and a narrower particle size distribution than has been possible to achieve in ball mills so far.

    The mixer mill MM 200 is a compact versatile benchtop unit, which has been developed specially for dry grinding of small amounts of sample.
    It can mix and homogenize powders in only a few seconds. It is also perfectly suitable for the disruption of biological cells as well as for DNA/RNA extraction.

    You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.

    Application Examples

    Alloys, Animal Feed, Bones, Ceramics, Cereals, Chemical Products, Coal, Coke, Drugs, Glass, Grains, Hair, Minerals, Oil Seeds, Ores, Paper, Plant Materials…

    Product Advantages

    • Reproducible, efficient grinding, mixing and homogenization in seconds
    • Powerful grinding by impact and friction, up to 25 Hz for up to 20 samples per run
    • 9 SOPs can be stored
    • Wide range of accessories including various jar and ball sizes, adapter racks, grinding tool materials

    Function Principle

    The grinding jars of the MM 200 perform radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. Also, the movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample.
    The degree of mixing can be increased even further by using several smaller balls. If several small balls are used (e.g. glass beads) then, for example, biological cells can be disrupted. The large frictional impact effects between the beads ensure effective cell disruption.
