Planetary Ball Mill PM 100: Precision Grinding at Its Finest
When it comes to high-efficiency laboratory milling, the Retsch PM 100 stands out as a top-tier choice for scientists, researchers, and material engineers. Designed by Retsch, a renowned German manufacturer of scientific instruments, this planetary ball mill has transformed the way fine grinding and mixing are performed at the laboratory scale.
In this article, we explore the key features, working principles, benefits, and applications of the PM 100 in detail — and how it boosts the productivity and efficiency of sample processing.
What is the Planetary Ball Mill PM 100?
The Planetary Ball Mill PM 100 is a bench-top unit designed for grinding and homogenizing small sample volumes with high speed. It utilizes a planetary motion system, in which jars rotate on their own axis and simultaneously revolve around a central axis. This dual motion generates extremely high centrifugal forces, enabling rapid size reduction of even the hardest materials.
How Does the PM 100 Work?
In the PM 100, a grinding jar is mounted eccentrically on a sun wheel. The jar rotates in the opposite direction of the sun wheel with a 1:2 speed ratio. As a result, the grinding balls inside the jar experience a combination of impact, friction, and shear forces.
This movement is ideal for:
Reducing hard solids
Preparing emulsions
Material research
The machine allows users to control grinding speed, set timer cycles, and achieve consistent, reproducible results.
