Plastication by kneading is done in variable shear roll mixers, in rotor mixers of the Banbury or Wemer-Pfleiderer type, or in twin-screw extruders or in special mixers. Plastication made in two-roll mixers is not economical and it is used mainly for batch production or to mix substances of different natures. For continuous line production, single or twin-screw extruders or a Buss KO-Kneader are used. These mixers or extruders operate in a friction mode this friction is obtained by a horizontal backward and forward motion of the screw. The screw may have threads or flights of regular width or of lai ger width and slantly cut in the rotational direction (see Fig. 14.10). Homogenization in these machines is so efficient that even fish-eyes present in PE and suspension polymerized PVC can be disaggregated [8]. [Pg.226]
