An improvement is provided in an apparatus and method for dispersing pigment in a liquid. The apparatus includes a vessel for holding liquid dispersing medium, a rotatable stirrer shaft, an impeller affixed to the shaft, a motor capable of rotating the shaft, and a support structure for positioning the motor to rotate the shaft with the impeller, and for positioning the impeller within the vessel. The improvement comprises using, as an impeller, a dispersing impeller in the form of a disc of radially-extending stiff wires, the parallel corrugated sides of the impeller being formed from the outermost layer of the trim length of the wires, and the face of the impeller being formed from the ends of the wires. A method of dispersing solids using the above-described apparatus is also described. |
