Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel.Ball mill is typically used to grind and or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation. The main factor contributing is the shear force applied by the balls. Using only shear force, one can produce large graphene flakes.

To avoid undesired contamination of the sample through abrasion, we offer a selection of 3 different material types. Normally, grinding bowls and balls of the same material are used.In addition to the instrument settings, the filling level of the jar is crucial for the success of the grinding process in mixer jar mills. A jar filling should consist of about 1⁄3 sample and 1⁄3 ball charge (pieces). The remaining third is the free jar volume that is necessary for the free movement of the balls.
