Modular mixing apparatus including interchangeable fluid processing means

A method of processing a thermoplastic fluid mixture in a modular mixing apparatus

• characterized by dividing a helically moving mass of the fluid mixture into a plurality of circumferentially spaced apart streams of material, guiding the spaced apart streams of material along undulating linear paths of travel of relatively short axial length, cutting across the spaced apart streams of material to carry out subdivision of the separated streams of material and then discharging the subdivided material into a die member.

A method of processing a thermoplastic fluid mixture by means of an extruder apparatus which includes an extruder screw, a barrel in which the screw is mounted for rotative movement and a modular mixing apparatus attached to the extruder screw

• characterized in that a helically moving mass of the fluid mixture leaving the extruder is brought into contact with rotating shear ring means to cut off portions of the mixture, is then guided through a stationary sleeve along spaced apart undulating paths of travel of relatively short axial length, thereafter is subjected to further cutting and is finally discharged into a die member.

• characterized in cutting across a helically moving mass of the fluid mixture to separate portions of the mixture into a plurality of separated streams of material, guiding the streams of material along undulating linear paths of travel of relatively short axial length and then subjecting the separated streams of material to further mixing and cutting and discharging the resulting mixture as a homogeneous mass.
