SE-150 Single Screw Extruder
SE-150 single screw extruder: 150 mm, 90–132 kW, 500–1,000 kg/h — the mid-large recycling size and the standard second stage of the KTE/SE two-stage family.

The SE-150 carries 500–1,000 kg/h at 90–132 kW: a full-time recycling machine at industrial rate, and the pressure stage behind the KTE-65B / SE-150 two-stage line for 85% filler and PVC duty.

Parameters
| Model | Screw dia. (mm) | L/D | Motor (kW) | Output (kg/h) |
|---|---|---|---|---|
| SE-150 | 150 | 25–33 | 90–132 | 500–1,000 |
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
Between the SE-120 (300–600 kg/h) and the SE-180 (800–1,500 kg/h). Its two-stage roles: second stage of the KTE-65B/SE-150 line, discharge of the KNE-400 and KNE-800 kneader lines, and both stages of the SE-150 / SE-150 film and woven-bag line.
What it runs
Duties: PP/PE regrind and flake at 600–800 kg/h, PVC compound finishing, masterbatch discharge from kneaders, and film/woven-bag recycling as the SE/SE mid size.

Configuration options
Every SE model is quoted with the feeding and filtration that its material needs, because a single screw only works as well as what is pushed into it. On a SE-150 line the options that matter: forced feeder for low-bulk-density regrind, hydraulic screen changer (2–4 screens) for contaminated input, L/D 28 or 33, and strand, water ring or hot-face pelletizing. Barrel and screw metallurgy follows the abrasive load of the scrap stream.
FAQ
What decides between an SE-150 and an SE-180?
Feed and forecast: 800 kg/h class and under with mixed input suits the 150; sustained 1,000 kg/h and woven-bag bales push to the 180. Motor size (132 kW ceiling) is the practical tell.
How is the two-stage role different from recycling duty?
As a second stage the screw geometry is deep-flighted and low-shear — it pumps, it does not compound. The same frame serves both careers; the screw set differs and is specified at order.
Does the SE-150 need a melt pump for pelletizing?
Not always — with gravimetric feeding the screw's own stability is often sufficient. On film-grade or tight-tolerance pellets, a pump removes the last pressure ripple; we quote it when the spec demands.
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.

SE-150 single screw extruder — the short version
Note on SE-150 single 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.
