 Kneading elements

Kneading elements form an important functional part of the co-rotating twin screw extruder. The melting process is generally carried out in theKneading elements . Standard kneading blocks are characterized by the length, number of discs and the offset angle between the discs.

With high quality, the Kneading elements assure plastic molecular mixing, cutting as well as reacting among themselves etc.


Type of Kneading elements

For the melting zone , according to the requirements of different materials and working conditions. the use of "eccentric" Kneading elements  for material with greater care, has been proven successfully. And double-flight elements can be used symmetrically in deep cut machines.

The tri-lobe kneading block used more for high- yield extruders, which has many advantages such as good feed angles, a low flight depth and full self-cleaning.

The barrier kneading elements  is generally designed with a feed characteristic. And can effect combined with self-cleaning and feed. it can also be used in conjunction with a barrier.
