KTE-36D Lab Twin Screw Extruder
KTE-36D: 35.6 mm, 2×352 N·m, 22–37 kW, 20–150 kg/h — the strongest lab screw we build, for severe formulations at pilot rate. A reference KTE-36D lab twin screw extruder page from Kerke.

The top of the lab ladder: 35.6 mm screw with 2×352 N·m — production-grade torque at pilot scale — and 20–150 kg/h. Glass fibre, 88% filler, XLPE and reactive systems run here before they run anywhere expensive.

Parameters
| Model | Screw dia. (mm) | Speed (rpm) | Motor (kW) | Torque (N·m) | Output (kg/h) |
|---|---|---|---|---|---|
| KTE-36D | 35.6 | 500–600 | 22–37 | 2×352 | 20–150 |
Reference output measured on the stated material family; subject to a material trial. Motor and torque values are per machine, not per screw shaft.
Where it fits in the range
The ceiling of the lab class: KTE-36B below (2×210 N·m), the KTE-50D above as the smallest production D-class machine. The 36D's gearbox philosophy mirrors the production D family — the recipe you validate here scales without re-thinking the machine.
What it runs
Duties: glass-fibre and high-filler pilot batches, cable compound qualification (XLPE, HFFR), reactive extrusion pilots (TPU, MAH grafting), and pre-production trials for KTE-65D/75D projects.
Glass Fiber Compounding Line
Glass fibre reinforcement is not about getting fibre in — it is about not breaking it on the way through. Screw geomet…
HFFR / LSZH Cable Compound Line
HFFR compound carries 50–60% metal hydroxide, which starts decomposing around 180 °C. The line has to disperse it thor…
TPU Reactive Extrusion Line
TPU is polymerized inside the extruder, which makes it the one product where moisture is not a quality issue but a sto…
Configuration options
Lab models share the building-block platform of the production range, so a screw set validated on a KTE-36D translates upward. Options: transparent or split barrel for teaching, torque and melt-pressure logging to CSV for R&D records, strand or water-ring pelletizing at this scale, and a quick-change element kit so one machine serves several formulations in a day.
Lab work at Kerke follows the same discipline as production: every run is logged with barrel temperatures, screw speed, feeder setting and output, so the report you receive is a record, not an impression. A typical screening week covers five to ten configurations; a full pilot campaign — trial, re-run, scale-up note — fits in two, and the scale-up note travels with the recipe to whichever production KTE the duty lands on.
FAQ
Why does a lab machine need 2×352 N·m?
Because severity does not scale down: 40% glass fibre at bench scale demands the same torque per volume as in production. The 36D lets the formulation — not the gearbox — set the limit.
Can the 36D stand in for a production machine?
For days, yes; for months, that is the 50-class's job. The 36D's role is the last lab step before capital equipment — its data is production-shaped.
What does the 150 kg/h top of the band correspond to?
Benign formulations at full speed; glass-filled and 90% filler duties plan 60–110. The trial report per formulation is the number we and you both plan on.
Where these numbers come from
Parameters come from the Kerke parameter table and product master data sheet, cross-checked against commissioning records for the same model and duty. Where a catalogue value and a trial value disagree, the trial value is the one we quote.

KTE-36D lab twin screw extruder — the short version
Note on KTE-36D lab twin screw extruder: what separates one machine from another is torque class, L/D and the wear package matched to your material, not the build standard. Shortlist from the tables, then confirm the choice on a trial with your own powder.
Planning an upgrade this quarter? Send the material and the target output — the configuration comes back within one working day.
Every quotation lists the wear package as a separate line, so its cost is visible from day one.
Questions are answered the same day, in English or Chinese.
Note on KTE-36D lab twin screw extruder: the data on this page was last verified on our own test line in Nanjing.
