KTE-36 Lab Twin Screw Extruder
KTE-36: 35.6 mm, 15–18.5 kW, 20–60 kg/h — the base pilot machine for continuous small-batch production and extended validation runs. A reference KTE-36 lab twin screw extruder page from Kerke.

The base 36-class pilot: 35.6 mm screw, 2×176 N·m, 20–60 kg/h. It bridges the lab and the production floor — long enough runs to feed a small market, short enough runs to change the recipe weekly.

Parameters
| Model | Screw dia. (mm) | Speed (rpm) | Motor (kW) | Torque (N·m) | Output (kg/h) |
|---|---|---|---|---|---|
| KTE-36 | 35.6 | 500 | 15–18.5 | 2×176 | 20–60 |
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 36 family has four rungs: base KTE-36, KTE-36B (2×210 N·m, 20–100 kg/h) and KTE-36D (2×352 N·m, 20–150 kg/h). Below them, the KTE-25D covers severe screening; above, the KTE-50B starts the production range.
What it runs
Duties: pilot batches for market qualification, small commercial production of speciality compounds, extended formulation validation, and universities' continuous-process teaching.

Configuration options
Lab models share the building-block platform of the production range, so a screw set validated on a KTE-36 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
KTE-36 or KTE-36B — how do they differ?
Torque and band: 2×176 N·m with a 20–60 kg/h band versus 2×210 N·m at 20–100. The base 36 is the price-conscious pilot; the B adds headroom that severe carriers eventually use.
Can a KTE-36 produce pellets for sale?
Yes at its scale — several customers run pilot batches for customer qualification on the 36 class before ordering a production line. The pellets are commercial-grade samples.
What downstream fits the 36?
Strand or water-ring pelletizing at small scale, with the same dryer and sieve logic as production — deliberately, so the pilot teaches the whole process, not just the screw.
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-36 lab twin screw extruder — the short version
Note on KTE-36 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.
