Supersonic gas flow for preparation of ultrafine silicon

07-11-2018Additionally, the hand grinding is merely suitable for preparation of gram-scale substances. Although the mechanical ball milling is able to overcome these drawbacks, some challenges still remain. For example, the violent ball milling induces an obvious thermal effect, which can break the structure of some substances.

Ultrafine Grinding with Laboratory Ball Mills

06-10-2014In the planetary ball mill, every grinding jar represents a 'planet'. This planet is located on a circular platform, the so-called sun wheel. When the sun wheel turns, every grinding jar rotates around its own axis, but in the opposite direction. Thus, centrifugal and Coriolis forces are activated, leading to a rapid acceleration of the grinding balls (see Figure 4).
