What is the finest grind size achievable with Retsch ball mills?
Retsch planetary ball mills such as the PM 100 can achieve final fineness down to 1 micron (µm) depending on material hardness, grinding jar material, and run time. For nanoscale grinding requirements, Retsch's high-energy ball mills can reach submicron particle sizes. Contact us with your material type and target particle size for a specific recommendation.
