Planetary ball mills are used wherever highest demands are placed on speed, fineness, purity, and reproducibility. They pulverize and mix soft, medium-hard to extremely hard, brittle and fibrous materials and easily achieve grind sizes in the low micron or even in the nanometer range.

The Planetary Ball Mill PM 100 is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material per batch.

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.

The planetary ball mill is a high-energy type mill that can be manufactured in several models for laboratory and production uses, in order to meet the specifications of certain applications. In general terms, its use is restricted to the work of reducing the sample size in milling processes.

Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis. But their unique design takes advantage of centrifugal force and the Coriolis effect to grind materials to a very fine or even micron size.

RETSCH Planetary Ball Mills are perfectly suited for processes like mechanical alloying or mechanosynthesis. For most reactions, the 1:-2 speed ratio of jar to sun wheel of the models PM 100 and PM 200 is fully adequate, as the ball charge produces enough impact energy. However, greater energy is required for some reactions.

PQ-N4 series planetary ball mills may be used for mixing, homogenizing, fine grinding, mechanical alloying, cell disruption, small volume high-tech material production and even colloidal grinding. They are the ideal wet/dry milling tools for acquiring research samples with high efficiency and low noise.

Planetary Ball Mills are used wherever the highest degree of fineness is required. In addition to 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.
