High energy ball mill for ultrafine grinding
In the fields of material science or nanotechnology, achieving ultrafine grinding is a critical step for obtaining particles smaller than 1 micron. Traditional milling methods can be inadequate due to their inability to reduce particle sizes to the desired levels consistently.

Grind materials to nanoscale particles
The High Energy Ball Mill Emax from Retsch is designed for ultrafine grinding with a rotational speed of 2000 rpm, enabling efficient size reduction down to 0.08 µm. This makes it highly effective for nanoscale grinding. The ball mill utilizes a highly effective size reduction mechanism, combined with water cooling to permit continuous operation without risk of overheating. It accommodates a sample volume up to 2 x 45 ml and is ideal for applications where particle sizes down to the ultrafine range are required. The system allows for consistent and rapid grinding, making it suitable for various industries, including materials science, nanotechnology, and pharmaceuticals.
