KTE-T-52D Triple Screw Extruder
KTE-T-52D triple screw extruder: 51.4 mm, 100–300 kg/h — the lab-to-pilot bridge for black and colour masterbatch where dispersion must be proven early.

The smallest KTE-T: 51.4 mm triple screw, 100–300 kg/h, built to prove triple-screw dispersion on pilot volume before committing to a production line. Black and colour masterbatch at 20–45% pigment is its natural duty.

Parameters
| Model | Screw dia. (mm) | Output (kg/h) | Typical product | Note |
|---|---|---|---|---|
| KTE-T-52D | 51.4 | 100–300 | Black masterbatch, colour | Lab-to-pilot bridge |
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
Bottom of the triple-screw family: the KTE-T-65D (200–500 kg/h) is the production step, followed by the KTE-T-75D and KTE-T-95D. Against a twin screw of similar size, the third screw buys one more folding flank — the reason dispersion targets close at shorter L/D.
What it runs
Duties: carbon black masterbatch at 30–40% CB on pilot scale, high-concentration colour masterbatch, and R&D work where the dispersion mechanism itself is the subject of study.

Configuration options
The centre screw of the KTE-T-52D turns opposite the two outer screws, so material is folded twice per flight instead of once — the reason dispersion targets are met at L/D 32–40 where a twin screw needs 44–52. Options to settle at quotation: screw speed ceiling against carbon black grade, water ring or underwater pelletizing (both common on KTE-T), and the liner package, because 30–40% carbon black is the most abrasive duty we build for.
FAQ
Why choose a triple screw at pilot scale instead of a twin?
Because the dispersion result you validate is the one you will scale: the KTE-T-52D folds material twice per flight, so black masterbatch hits its dispersion target at L/D 32–40 — and the same geometry scales onto the 65D/75D.
Can the KTE-T-52D run glass fibre?
Not as the primary choice — fibre breakage runs higher than on a twin screw with late side feed. For reinforcement we quote the KTE-52D twin screw instead.
What output can a pilot expect on 35% CB?
Within the 100–300 kg/h band, plan on the lower half at 35% carbon black — dispersion-limited products run at conservative specific throughput. The trial report gives the measured figure.
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-T-52D triple screw extruder — the short version
Note on KTE-T-52D triple 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.
