Extrusion Screws througput

Extruder #1 througput is known. This tool can calculate througput of extruder #2 in the same working conditions : polymer, pressure, temperature. This is a practical method as decision-making tool.

Screw #1

D1 = barrel diameter

L1 = lead length L/D

N1 = speed rev/min

Q1 = througput kg/h

Screw #2

D2 = barrel diameter

L2 = lead length L/D

N2 = speed rev/min

GO!

Q2 = througput kg/h
