ABSTRACT:
A stirred ball mill assembly includes multiple vessels each having a body supporting sets of magnets rotatable with respect to the body. Each vessel defines an enclosed milling chamber, and has a stirring arm assembly extending in the respective enclosed milling chamber and connected for rotation with the respective sets of magnets. The sets of magnets and the stirring arm assembly are completely enclosed within the respective vessel. The vessels are configured to be stacked with one another so that adjacent ones of the sets of magnets are magnetically coupled with one another. A drive motor assembly has another set of magnets magnetically coupled with one of the sets of magnets of the stacked vessels. The drive motor can rotate the stirring arm assemblies within the milling chambers of the milling chambers of the stacked vessels via magnetic coupling of the magnets.
