Problems solved by technology

However, such non-intermeshing drums do not provide inherently reasonably good distributed (broad) mixing of the materials being mixed.
In addition, the use of such non-intermeshing drums is characterized by an undesired temperature rise of the materials being mixed

Embodiment Construction

[0023] Such as figure 1 As shown, a high-intensity internal mixer of the batch type, generally designated by the reference numeral 20, in which a pair of non-intermeshing drums 21 and 22 of the present invention may be advantageously employed, comprising vertical Reciprocating pressure head 24, the pressure head in figure 1 It is movable between the raised position shown and the lowered operative position 24' shown in dotted outline. The head 24 is used to move the ingredients to be mixed down into the mixing chamber 26 . In its operating position 24', when the material is thoroughly and vigorously mixed by the fins on the two counter-rotating drums 21 and 22, as will be described below, the head possesses the ability to be mixed. The force exerted by the material in chamber 26 and the two drums rotate about spaced apart parallel horizontal axes as indicated by arrows 23 and 25. figure 1 The left drum 21 is shown rotating in a clockwise direction about its axis, and the rig...

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...
