The internal batch mixer includes a housing defining a mixing chamber, where the mixing chamber includes first and second substantially circular chamber cavities in open communication with one another at a central region of the mixing chamber. The first and second non-intermeshing, counter-rotating winged rotors are respectively rotationally mounted within the first and second substantially circular chamber cavities, such that the central region of the mixing chamber defines an interacting mixing region between the first and second non-intermeshing, counter-rotating winged rotors. The first and second non-intermeshing, counter-rotating winged rotors are driven to counter-rotate with respect to one another. Each rotor has a substantially helical contour and a blade portion divided into three separate wings.

A kneading device uniformly kneads materials to be kneaded while efficiently and quickly kneading the materials to be kneaded. A kneading device includes a kneading chamber accommodating materials to be kneaded and a pair of rotors. The pair of rotors is rotated in the kneading chamber and kneads the materials to be kneaded by a plurality of kneading blades. The plurality of kneading blades in each rotor is composed only of inclined blades inclined to the same direction in a rotational direction of the rotor with respect to an axial direction of the rotor when the rotor is developed into a planar state. The rotor has bent blades which are bent at bent portions to change tilt angles with respect to the axial direction of the rotor in the plurality of kneading blades.

The continuous treatment device (10) includes a tank (11) of elongated shape and that determines a mixing chamber (15) which includes, at a first end, at least one inlet orifice (12) for the raw material and, at a second end, at least one outlet orifice (13) for the treated material, and also, between these orifices, at least one agitator shaft (16) equipped with blades (17) suitable for continuously mixing and advancing the material in the mixing chamber (15) from the inlet orifice to the outlet orifice. The device also includes a mixing screw (25) in the bottom of the tank, which is positioned in the mixing chamber (15), below and parallel to the at least one shaft (16), and which is suitable for being rotated, about at least one direction of rotation, the opposite way from the advance of the material from the inlet orifice to the outlet orifice.

A device for driving a plurality of rotatable agitators for use in a static batch reactor system, a reactor bottle cap for use with the rotatable agitator driving device and a static batch reactor system which includes the rotatable agitator driving device and bottles fitted with the reactor bottle cap are disclosed. The rotatable agitator driving device includes a planar case having first and second opposite faces, a plurality of drive heads projecting from the case through the second face and a gear train protectively housed in the case. The gear train includes a driver gear having a coupling for receiving drive from a motor, a set of idler gears and a set of driven gears. Each driven gear attached to a respective drive head for driving a rotatable agitator. The gear train is configured to cause the drive heads to rotate at the same rate.

A method for producing a thermoplastic elastomer composition comprising using a twin screw kneader to melt-knead a thermoplastic resin and an elastomer; the twin screw kneader having at least two raw material inlets including a first raw material inlet and a second raw material inlet provided at a position separated by 15D to 38D on a downstream side from the first raw material inlet, where D is a cylinder inside diameter of the twin screw kneader; the elastomer being fed in a divided manner from the first and second raw material inlets; a proportion of the elastomer fed from the second raw material inlet being from 10 to 60 vol % of a total amount of the elastomer; and the elastomer being melt-kneaded in a kneading zone having a length of from 0.5D to 20D in a cylinder axis direction of the twin screw kneader.

An agitator assembly for use with industrial mixers that includes at least two rotating agitators, wherein each rotating agitator includes an agitator shaft, wherein the agitator shaft defines an axis of rotation extending from a first end of the agitator shaft to a second end of the agitator shaft; and first, second, and third sweep blades mounted on the agitator shaft, wherein the pitch angle of each sweep blade relative to the axis of rotation of the agitator shaft is between 30-60; and wherein the rotating agitators rotate in opposite directions relative to one another when the assembly is in use.
