Hello,

I have previously worked with parallel co-rtating twin screw extruders-cascade systems for soft PVC compounding. These extruders work great (berstoff, WP, farrel).

I am currently in the process of buying a twin screw for my factory to process soft PVC compounds--My question is

1. How does a conical counter rotating twin screw extruder (not a cascade system) compare with the parallel co-rotating twin screw extruder.
2. Will it do the same job as the parallel

There is a major cost difference between the conical versus parallel (parallel being 2.5 times more expensive). Any professional advice in this regards is appreciated. Also if there is a web lonk available to see the comparison, then I will appreciate that also.

Best Regards,
Vishal Kadakia

I believe conical twins are used primarily for rigid PVC profile work. You should consider a parallel counter rotating machine for flex PVC compounding.
