Planetary Ball Mill Systems
High-Energy Grinding for Ultrafine Particle Size Reduction and Advanced Materials Research
Planetary Ball Mills provide the high-energy impact and friction required for rapid, reproducible grinding of soft, hard, brittle, fibrous, and composite materials. Their counter-rotating grinding jars generate intense centrifugal and Coriolis forces, producing analytical fineness below 1 µm and, with wet colloidal grinding, particle sizes below 100 nanometers.
The product family ranges from the compact, single-station PM 100 and dual-station PM 200 to the powerful 800-rpm PM 300 and the four-station PM 400 for larger sample volumes and higher throughput.
A broad selection of grinding jar sizes, ball materials, operating programs, aeration lids, and pressure-and-temperature monitoring options allows each system to be configured for dry grinding, wet grinding, mixing, homogenization, mechanical alloying, mechanosynthesis, co-crystal screening, and advanced materials research.

How Planetary Ball Mills Work
Planetary ball milling uses one or more sealed grinding jars mounted on a rotating support disc. As the support disc turns, each jar rotates around its own axis in the opposite direction, generating powerful centrifugal and Coriolis forces.
These combined motions accelerate the grinding balls inside the jar, causing repeated high-energy impacts, compression, and friction against the sample material and jar walls. The continuous collision and shearing action rapidly reduces particles, blends components, and creates highly uniform samples. Depending on the grinding media, speed, time, and whether the process is performed dry or wet, planetary ball mills can achieve fine, ultrafine, and even nanometer-scale particle sizes.
