Abstract

Four wing rotors for used in an internal batch mixer. The rotor has two long wings, and these two long wings have different approach angles and helix angles. The rotor has two short wings and these short wings also preferably have different helix angles and approach angles. The rotors provide improved distributive and dispersive mixing allowing for greater productivity in processing materials and producing more homogeneously mixed materials at lower discharge temperatures.

Description

technical field

[0001] The present invention relates to improved bowls for use in internal batch mixers having two counter-rotating non-intermeshing four-bladed bowls. The four-wing drum of the present invention can disperse and mix the materials in the batch mixer. The present invention also relates to batch mixers employing two of the novel four-blade rotors of the present invention and to improved batch mixing using such batch mixers having improved four-blade rotors cylinder. Background technique

[0002] The present invention relates to batch type high intensity internal mixers having a mixing chamber shaped to accommodate two counter rotating non-intermeshing vaned bowls. The batch of compositions to be mixed into a homogeneous mass is fed down a vertical chute into the mixing chamber and pushed down by the pressure of a ram on the chute. The ram is hydraulically or pneumatically actuated. During mixing of the batch, the lower surface of the ram forms the upper par...
