<p>A mixing apparatus for blending one or more relatively viscous liquids into a homogeneous mixture, the apparatus including a fixed vessel, a pair of rotors rotatively housed in the vessel, each rotor rotating on its own rotary shaft, the rotary shafts being rotated in opposing directions, the rotors having helical mixing vanes thereon wound oppositely in directions and differently in number, wherein the outside diameters D1, D2 of the rotors, the distance A between the rotary shafts, the rotating angular velocities of the rotors, and the number of the helical vanes are defined by the numerical criterion: A is smaller than 1/2(D1 + D2), and the ratio between velocities of the rotors is equal to the inverse number of the ratio between the numbers of the helical mixing vanes.</p> |
