Abstract
A mixing apparatus for mixing two or more materials, includes a separating plate Upstream of a mixing zone having a plurality of vortex generators attached to the plate to create large scale longitudinal vortices in the materials as they pass the plate for rapid, controlled mixing in a short longitudinal distance. The vortex generators are arranged in a row transverse to the flow direction of the materials. The vortex generators each comprise three triangular-shaped surfaces joined to form a three sided wedge having a top surface and opposite sides surfaces that project into the flow path. The side surfaces are joined at an acute angle. The top surface is oriented at an angle to the plate. The angles may be adjusted for the type of materials to be mixed.
