8000M Mixer/Mill® High-Energy Ball Mill

The 8000M Mixer/Mill is a high-energy ball mill that grinds up to 0.2 - 10 grams of dry, brittle samples. The vial, which contains a sample and one or more balls, is shaken in a complex motion that combines back-and-forth swings with short lateral movements, each end of the vial describing a figure-8. The clamp's motion develops strong G-forces in the vial, to pulverize the toughest rocks, slags and ceramics.

Grinding and mixing vials are available in: hardened steel, stainless steel, tungsten carbide, alumina ceramic, zirconia ceramic, silicon nitride, agate, polystyrene, methacrylate, and polycarbonate. CE Approved.

Applications include: Mechanical alloying, slurry grinding, blending powders and mixing emulsions.

Typical samples include: Rocks, Minerals, Sand, Cement, Slag, Ceramics, Catalyst Supports, Glass, Pharmaceuticals, Plant and Animal Tissues, Cannabis, Seeds, Paints and Ink.
