KTE-36B Lab Twin Screw Extruder
The KTE-36B lab twin screw extruder is the pilot workhorse: 35.6 mm, 2×210 N·m, 20–100 kg/h — where customer samples become pilot batches.

The 36B is the pilot workhorse of the range: 35.6 mm, 18.5–22 kW, 2×210 N·m, 20–100 kg/h. It is the machine behind pilot batches for market qualification — several customers run their first commercial pellets on one before ordering a production line.

Parameters
| Model | Screw dia. (mm) | Speed (rpm) | Motor (kW) | Torque (N·m) | Output (kg/h) |
|---|---|---|---|---|---|
| KTE-36B | 35.6 | 500–600 | 18.5–22 | 2×210 | 20–100 |
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
Middle rung of the 36 family: base KTE-36 below, KTE-36D above (2×352 N·m, 20–150 kg/h). Against the lab class, the KTE-25D screens severe recipes; against production, the KTE-50B is the next floor up.
What it runs
Duties: pilot batches for customer qualification, masterbatch development in kg quantities, speciality compound small production, and process validation before capital request.

Configuration options
Lab models share the building-block platform of the production range, so a screw set validated on a KTE-36B 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
Is a complete skid available for a 36B pilot line?
Yes — main machine, gravimetric feeder, die and pelletizer, control cabinet, spare kit and English manual fit one 20 ft container. That is the standard pilot-line quotation.
36B or 36D for a pilot lab that will see glass fibre?
The 36D's 2×352 N·m is the honest answer for glass and high filler; the 36B is right for masterbatch and general compounding. Torque is the fixed choice — screws and barrels can be changed later.
How long does a pilot campaign on a 36B take?
A typical validation week covers 5–10 configurations with full downstream data. The report template matches what we use for production trials, so the numbers compare.
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-36B lab twin screw extruder — the short version
Note on KTE-36B 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.
