Feeding and pre-heating of the material.
Heating and agglomeration.
Sealing-off of vent zone in support of the plasticizing process.
Degassing & venting of the melt.
Completion of melting, homogenizing & outputting of melt.

ParallelComparison of the meshing Surface Area
From above graph, if is evident that – the meshing surface area is higher for conical twin screws compare to the same diameter parallel twin screws hence homogeneous and better melt quality.
From the graph, it can be derived that by using conical twin screws, compression continuity can be maintained throughout the length of the screw and hence better quality of the end product.
The conical idea -
Brilliant when it was born, and still brilliant today…
So, Lets have a look at the key features of NCMT series Extruders…….
For easy flowing dry-blends with constant quality & apparent density, a sliding hopper is used which allows for three positions Production, Shut-off & Emptying
The venting port on the barrel is coupled to specially designed efficient venting pump for effective removal of air and gases generated during the plastification process
