kneading block and conveying element

Conveying Elements
Standard or special design conveying elements are available in nitrided through-hardened, corrosion or wear resistant alloys and are thoroughly inspected and tested to assure the highest quality. High volume feed elements provide improved material intake for materials with poor feeding characteristics.

Kneading Blocks and Dispersive Mixing Elements
Twin screw extruder mixing and kneading elements are designed in a variety of lengths, pitches and pitch directions. Kneading blocks are constructed using several disks of equal or varying widths spaced at equal distances from each other. The result is precise shear, melt and energy control. In addition, this mixing process provides homogeneous melt and controlled dispersion-distribution of additives. In traditional twin screw extruders, the melt is kneaded and sheared by shear locks, mixing lobes, or cut-flight screw elements.

The order in which kneading and mixing components are arranged can be freely selected depending on product formulation. The positive engagement of the screw segments on the screw shaft enables individual segments to be easily replaced and thus ideally adapted to continuous high output.
