The quality control testing of fluorescent colorants by the manufacturers has been based upon attempted simulation of the compounders testing. The colorants are dispersed by either an injection molder, extruder, or a Banbury mixer into HOPE for observation in both mass tone and tint forms. In addition, a common method of display is a side-by-side pressout as performed on a hydraulic press. Carefully trained technicians perform visual observations while those in the fluorescent industry await the development of technology which will allow for adequate computerized color measurement. 

Simulating Flows in the Banbury Mixer with Three-Dimensional Models 885... 

As they simulated the flow in a Banbury type mixer, Gramann and Osswald [11] were able to track particles throughout the processes. Figure 12.3 shows the deformation that can take place as the rotors turn. 

Simulated fluid deformation in a Banbury-type mixer... 

Using finite element techniqnes, a mathematical model was developed for the two-dimensional analysis of non-isothermal and transient flow and mixing of a generalised Newtonian fluid with an inert filler. The model could incorporate no-slip, partial-slip or perfect-slip wall conditions using a universally applicable numerical technique. The model was used to simulate the convection of carbon black with flowing rubber in the dispersive section of a tangential rotor (Banbury) mixer. The Carreau equation was used to model the rheological behaviour of the fluid in this example. 31 refs.
