  • Patent number: 4693609
    Abstract: A mechanism for agricultural chemical formulation including a mixing tank and a dispersion tank. A rotatable shar blade is mounted within the dispersion tank which has a bottom wall and a side wall. The formulation is transferred from the mixing tank into the dispersion tank through an opening in the bottom wall with the shar blade being in close adjacency to the opening in order to permit the shar blade to strike the formulation as soon as it enters the dispersion tank. The formulation is re-circulated back into the mixing tank and the re-circulation between the two tanks is continued until it reaches the correct consistency.
