ABSTRACT:
An aerator for introducing and dispersing air as fine bubbles in a liquid-solid slurry has a lower body, an upper body and replaceable blades affixed between the upper and lower bodies. The blades have a body portion positioned between the upper and lower bodies and a projecting portion extending radially outwards. The upper body has a vertical axial bore which is connected to an air tube open to the atmosphere. As the aerator is rotated by rotation of the air tube, air is drawn through the air tube into the body of the aerator and is dispersed out through air exit ports between the blades into the slurry, without intake of slurry into the aerator.
