planetary ball mill

Planetary Ball Mills 101. 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.

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.

A numerical dynamic-mechanical model of a planetary ball-mill is developed to study the dependence of process efficiency on milling parameters like ball size and number, jar geometry and velocity of the revolving parts.

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 high-volume Ball Mill for high throughput applications. Max. speed 400 rpm, large sun wheel. Up to 10 mm feed size and 0.1 µm final fineness. 4 grinding stations for jars from 12 ml up to 500 ml, jars of 12 – 80 ml can be stacked (two jars each) GrindControl to measure temperature and pressure inside the jar.

incl. order data. Download. 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 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.
