Method of, and mixer for intimate blending of fine, dry, particulate solid materials with moist wet or slurried particulate solid materials

摘要

A blender is provided which is comprised of an impeller having at least three sets of blades, a first set of blades positioned near the inlet of the blender and a second set of blades positioned near the outlet of the blender are radially extending and pitched, said first and second set of blades having a differential in the average pitch relative to each other. The third set of blades positioned between the inlet and outlet sets, which may be pitched or unpitched, include blades which are curved toward both the first and second set of blades. The blender has particular application to the smelter art and is useful for the continuous blending and agglomeration of fine particulate materials.
