Abstract
Abstract Apparatus for continuously feeding selected ratios of materials to be mixed together. Accurate proportioning of the component materials is facilitated through the advantages of the invention. Since all ingredients are introduced continuously in the selected ratios, overrun problems are resolved and the exact amount of the mix required can be produced. Dry particulate materials in granular, pellet or powdered form and also liquid components of a mixture are contemplated by the invention. Thus the inventive device accomplishes the precise control of the blending of dry granular, slurry and liquid components on a continuous feed basis. The invention achieves this result through the maintenance of precise voltage ratios rather than voltage levels. Applicability is to vibrators delivering dry materials, augers delivering dry and/or slurry materials and also to pumps delivering liquid materials.
