Planetary ball mills for fine grinding of materials
In laboratories and research facilities, achieving ultra-fine particle sizes is crucial for materials development and analysis. Traditional milling techniques often fall short, requiring advanced solutions for routine sample processing, colloidal grinding, and mechanochemical applications.
Achieve ultra-fine grinding and precise mixing
The Planetary Ball Mills from Retsch are designed for high-speed and reliable pulverization to achieve fine particle sizes. These mills are equipped with multiple grinding stations, a unique speed ratio, and adaptable grinding jars and balls. The centrifugal and Coriolis forces generated within the mill produce high energy impacts and friction, leading to rapid particle size reduction. The versatility of these mills makes them suitable for both dry and wet grinding of soft, hard, brittle, and fibrous materials. Retsch’s Planetary Ball Mills support critical processes in laboratories, such as mechanochemistry, nanotechnology, and co-crystal screening. With models like the PM 100, PM 200, PM 300, and PM 400, they cater to varied sample volumes and methodological requirements. Notable features include material feed sizes of <10 mm, final fineness levels of <1 µm (and <0.1 µm for colloidal grinding), speed ratios of 1:-2, 1:-2.5, and 1:-3, and advanced measurement systems for monitoring pressure and temperature within the grinding jar. These mills ensure efficient and reproducible results across multiple industries, including pharmaceuticals, materials science, and chemical engineering.
