Abstract

Disclosed is a mixer consisting of a receptacle and an agitator capable of agitating material in the receptacle and conducting material to and from the receptacle. The agitator includes an engine, at least one agitator element disposed in the receptacle, and a drive shaft coupling the engine to the agitator element. The drive shaft carries a conduit, which is capable of conducting material to and from the receptacle. The conduit has an open proximal extremity disposed outboard of the receptacle and an open distal extremity disposed in the receptacle. The engine consists of radial vanes attached to the drive shaft and the drive shaft rotated to a chassis having a chamber substantially enclosing the vanes, an inlet leading to the chamber and an outlet leading from the chamber, in which the drive shaft is made to rotate in response to a flow of fluid acting on the vanes passing through the chamber from the inlet to the outlet.
