Planetary Ball Mills are used wherever the highest degree of fineness is required. In addition to the well-proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying. The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and therefore short grinding times.

Planetary Ball Mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. From benchtop size to pilot production size, from full-direction grinding to cryogenic grinding, our extensive portfolio virtually guarantees there is an appropriate standard solution that will meet your requirements.

Planetary Ball Mills FAQs

WHAT IS A PLANETARY BALL MILL?

A Planetary Ball Mill are smaller than common a Ball Mill 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. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else).

HOW DOES A PLANETARY BALL MILL WORK?

The term Planetary Ball Mill is derived from its unique kinematics: the grinding jars, which are mounted on the main rotation sun disk, rotate in the opposite direction around the centre of this disk.

Due to this movement, the sample is comminuted very effectively and fast by impact, shearing and friction forces resulting from ball-to-ball and ball-to-wall collisions.

With the planetary movement, the grinding bowl filling is subject not only to the force of gravity, as in the case with conventional ball mills, but centrifugal and coriolis forces further increase the kinetic energy of the grinding parts.

WHAT IS THE APPLICATION OF PLANETARY BALL MILLS?

Apart from the classical mixing and size reduction processes, the Planetary Ball Mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. They are widely used in:

  • Geology and Mineralogy
  • Ceramics
  • Chemistry
  • Biology
  • Pharmaceuticals
  • Metallurgy
  • Material Technology
  • Analysis Preparation
