APPARATUS FOR MIXING VISCOUS MATERIAL

摘要

An apparatus for mixing or homogenizing viscous material is disclosed. Stirrers, comprising multiple vane mixing blades are mounted on a pair of parallel shafts in corresponding spaced apart parallel tiers. Each vane has a working surface inclined relative to the shaft and offset relative to the vanes of an immediately adjacent blade. One shaft is advanced relative to the other so that the vanes intermesh. The inclination of the vanes in one blade is mirrored in sense to the other blade on the adjacent shaft, and the shafts are rotated in opposite sense so that the stirrers in each tier pump the material in the same relative direction when the shafts are so rotated.
