Planetary ball mills for fine grinding of materials
Optimize particle size and surface area in your samples with high-energy input and rapid pulverization for advanced material development and precise research applications.
Pulverizes and Homogenizes Materials for Research Applications
The Planetary Ball Mill PM Series, from Retsch, is designed for high-precision material pulverization and homogenization, catering to R&D laboratories, pharmaceutical manufacturers, and nanotechnology companies. Utilizing a counter-rotating jar mechanism, these mills generate significant centrifugal forces to rapidly reduce particle size to colloidal levels. Common applications include processing protein powders, APIs, and lithium-ion battery cathode materials. The PM Series offers batch processing capabilities with adjustable speed ratios from 1:-2 to 1:-3, providing flexibility for mechanochemical applications and co-crystal screening. Engineered for efficient processing, these mills operate with minimal energy consumption and are equipped with options for various jar and ball materials, including zirconium oxide for contamination-free grinding. Each model supports easy integration into lab environments, offering customizable grinding stations and PLC control for precise operation. With Retsch’s robust construction and ease of maintenance, the PM Series is a reliable choice for advanced material science research.
