When it comes to state-of-the-art laboratory milling, the PM 100 planetary ball mill stands out as a premium 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 enhances the productivity and efficiency of sample processing.
Introduction to PM 100 Planetary Ball Mill
The Planetary Ball Mill PM 100 is a compact lab-scale machine designed for grinding and homogenizing small sample volumes with maximum efficiency. 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.
Mechanism Behind the PM 100
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 collision, friction, and shear forces.
This movement is ideal for:
Pulverizing brittle materials
Mixing powder suspensions
Material research
The machine allows users to adjust rotation parameters, set timer cycles, and achieve consistent, reproducible results.
