KTE-T-65D Triple Screw Extruder

The KTE-T-65D triple screw extruder is the most-specified KTE-T: 62.4 mm, 200–500 kg/h — black masterbatch at 30–40% CB with dispersion a twin screw needs a longer screw to match.

Quick answer

The workhorse of the triple-screw range: 62.4 mm, 200–500 kg/h, built for black masterbatch at 30–40% carbon black and high-concentration colour. The centre screw's counter-rotation adds one folding surface per flight, which is why the same dispersion closes at L/D 32–40.

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

Production heart of the family: KTE-T-52D below for pilot work, KTE-T-75D above (400–800 kg/h) with water ring or underwater pelletizing. Against twin screws, the comparison is with the KTE-65D — same bore class, different mixing physics.

What it runs

Duties: black masterbatch 30–40% CB for film and injection grades, colour masterbatch where pigment wetting is the specification, and predispersions for downstream let-down. Filler masterbatch on a triple screw is possible but rarely the economic answer.

Configuration options

The centre screw of the KTE-T-65D 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

Is a triple screw better than a twin screw for black masterbatch?

For dispersion-limited products, yes at equal output and lower energy per kg: one more folding flank per flight means the same dispersion at L/D 32–40 instead of 44–52. For filling and general compounding the price difference is not justified.

Why not run glass fibre on the KTE-T-65D?

The intense folding that disperses carbon black breaks fibres; there is no late side-feed position that protects them. Reinforcement duty goes to a KTE-D twin screw.

What pelletizing pairs with the 65D?

Water ring is the common choice at this band; underwater where pellet density and dust-free handling are specified. The die face is designed for the pelletizer, so the choice is made with the quotation.

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-65D triple screw extruder — the short version

Note on KTE-T-65D 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.
