Problems solved by technology

That is, since the materials to be mixed are difficult to be uniformly mixed in the vicinity of the contact surface, there is a problem that the temperature of the materials to be mixed cannot be effectively controlled.
[0005] In addition, the limited contact area between the mixed material and the inner wall of the chamber also limits the temperature control

Abstract

A batch mixer having a barrel which forms a cylindrical sealed chamber having a section consisting of two mutually communicated circles, and two rotors housed in the chamber to mix a mixing material by rotation, at least one of the inner wall of the barrel and the surface of the rotor having a plurality of recessed parts or protruding parts. The recessed parts or protruding parts are formed of grooves or projections extended in the direction crossing to the rotating direction of the rotor rotated in the chamber to mix the material. According to this structure, a batch mixer excellent in the controllability of material temperature during mixing can be provided.

Description

technical field [0001] The present invention relates to an internal mixer for mixing materials to be mixed by rotating a mixing rotor in a mixing chamber. Specifically, the present invention relates to a structure for controlling temperature rise in a mixing chamber (material to be mixed) during mixing, and further relates to a structure for improving fluidity of the material to be mixed in the mixing chamber. Background technique [0002] The technology of internal mixers has been known for a long time. [0003] For example, there is a device disclosed in JP-A-9-220718. The device in this publication is a closed mixer with a chamber and two rotors. The chamber forms a cross-section of two communicating circular cylindrical sealed mixing chambers. The rotor is accommodated in the mixing chamber and is rotated to The mixed materials are mixed, and the first heat transfer passage is formed in the chamber. The first heat transfer passage is centered on each mixing rotor and r...
