Abstract
A mixing apparatus particularly useful in carbon black pelleting has two parallel pinned shafts. The pins on each shaft are arranged in a double helix fashion with the pins interdigitating. The pins of each double helix are composed of two subsets of pins arranged in a single helix which single helices are, however, axially offset from each other. Thereby at any given axial location alternatingly opposite pin action is provided in the interdigitating zone, while surging of power is avoided.
