Polytevo Series Dual Conical Twin-Screw Extruder
Product Detail
Polytevo Series Dual Conical Twin-Screw Extruder (ACS-7009ZSD) is a compact laboratory extruder with two sets of conical twin screws in an inverted, staggered layout that circulate the material back and forth without limit, with independently adjustable speeds of 1–120 rpm, eight temperature control zones and a maximum temperature of 400°C.
The ACS-7009ZSD is a compact instrument specially developed for mixing new materials, for use on test benches or in fume hoods. Two sets of conical twin screws are arranged in an inverted and staggered layout so that the material circulates back and forth without limit, and the rotating speed of each screw group is independently adjustable, which makes it suitable for formula verification of highly filled and high-viscosity materials. The minimum processing capacity is 10 mL.

Where it fits
Frequently asked questions
What is special about the two screw pairs?
Two sets of conical twin screws sit in an inverted and staggered layout so the material circulates back and forth without limit, and the speed of each screw group can be adjusted independently.
What is the smallest batch it can process?
The minimum processing capacity is 10 mL, and blending experiments can be carried out with only 5–15 g of raw material.
Which experimental modes are supported?
The rheology control software supports single-cycle blending, timed-cycle blending, continuous feeding blending, constant-speed blending and constant-torque blending.
How does it differ from the ACS-7009ZS?
The ACS-7009ZS has one pair of conical screws and 4 temperature control zones. The ACS-7009ZSD has two pairs, independent speed control of each screw group, 8 temperature control zones, 80 g material mass per cycle and 5 kg/h.
What power supply does it need?
AC 220 V, 50 Hz.
