Abstract
An improved magnetic mixer includes an agitator that includes a plurality of agitator magnets. A bearing arrangement allows the agitator to be magnetically levitated along the outer surface of a cylindrical vessel fitting located within a mixing vessel. The same magnetic force that is used to levitate the mixer drives the agitator. The magnetic force is preferably generated by a plurality of magnets which rotate within an aperture extending into the vessel fitting. By magnetically levitating the agitator, there is no thrust generated by the agitator against the vessel fitting which eliminates the need for thrust bearings and reduces the overall frictional forces. The low friction results in reduced particle generation, reduced power consumption and reduced maintenance compared to conventional magnetic mixers.
