Abstract
A simple mixing apparatus provides especially for the mixing of treatment fluids with suspensions having a consistency of about 2-15%. First and second cylindrical coaxial housing parts are provided, the second part having a larger diameter than the first part. A fluid inlet introduces fluid axially into the first housing part, and a fluid outlet expels treated fluid tangentially from the second housing part. Stirring and mixing is provided by first and second stirring members rotatable about a common axis, the first stirring member having a number of axially extending, radially upstanding ribs cooperating with similar ribs on the interior of the first housing part, and the second stirring member having a number of radially extending, axially upstanding ribs cooperating with like ribs formed in the second housing part. The suspension is fluidized by the stirring members, and the residence time of suspension with the apparatus is between about 0.01 and 2.0 seconds.
