The production-scale KTE-T: 71 mm triple screw, 400–800 kg/h, for black masterbatch plants and high-loading colour work. Three screws fold twice per flight, so 40% CB disperses at L/D 32–40 — shorter machines, shorter residence, less heat history.

Parameters
| Model | Screw dia. (mm) | Output (kg/h) | Typical product | Note |
|---|---|---|---|---|
| KTE-T-75D | 71 | 400–800 | Black / filler masterbatch | Water ring or underwater |
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
Above the KTE-T-65D (200–500 kg/h), below the KTE-T-95D (800–1,200 kg/h). The 75D is where triple-screw economics usually land: enough output for a commercial black masterbatch line, with pelletizing options — water ring or underwater — matched to the customer's downstream.
What it runs
Duties: black masterbatch 30–45% CB in commercial volume, fibre-free high-dispersion colour masterbatch, carbon black predispersion for masterbatch let-down, and conductive compounds where dispersion uniformity is the functional spec.

Configuration options
The centre screw of the KTE-T-75D 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
Water ring or underwater pelletizing on the 75D?
Both are common on KTE-T lines: water ring is simpler and suits 30–35% CB; underwater gives rounder, denser pellets and dust-free handling at higher loadings. The decision follows the pellet specification, not the extruder.
How does wear look at 40% carbon black?
It is the most abrasive duty we build: bimetallic liner and PM elements standard, wear parts quoted as a scheduled line item. Element life is tracked per tonne from commissioning records.
Can the 75D run filler masterbatch instead?
Technically yes; economically rarely — filler masterbatch does not pay for the third screw. That duty belongs to the KTE-75B or the KTE-75B / SE-180 two-stage line.
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-75D triple screw extruder — the short version
Note on KTE-T-75D 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.
