SE-200 Single Screw Extruder
SE-200 single screw extruder: 200 mm, 185–250 kW, 1,000–2,000 kg/h — the largest SE, for industrial recycling and as the pressure stage of the biggest two-stage lines.

The top of the SE range: 200 mm screw, 185–250 kW, 1,000–2,000 kg/h. Standalone it is an industrial recycling line for film and bag streams at tonnage; in two-stage duty it is the pressure stage of the KTE-95B / SE-200 line.

Parameters
| Model | Screw dia. (mm) | L/D | Motor (kW) | Output (kg/h) |
|---|---|---|---|---|
| SE-200 | 200 | 25–33 | 185–250 | 1,000–2,000 |
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
Top of the family: the SE-180 below (800–1,500 kg/h). Its two-stage career: behind the KTE-95B on high-filler and cable duty. Beyond its band, plants parallel lines — there is no larger single screw in the Kerke programme.
What it runs
Duties: industrial film/woven-bag recycling at 1,200–1,800 kg/h, large kneader discharge, cable compound finishing at volume, and municipal-scale rigid scrap lines.

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-200 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 does a 2,000 kg/h SE-200 line look like?
Shredding and washing upstream, compacting feeder, double-vent barrel, double-station screen changer, melt pump and underwater or water-ring pelletizing — the extruder is one station of a plant. We quote the plant, not just the screw.
Can the SE-200 serve as only a second stage?
Yes — that is its role behind the KTE-95B: deep-flighted, low-shear, full-speed pumping. The screw set differs from the standalone recycling build and is specified per duty.
What power and space should we plan?
250 kW-class main drive plus auxiliaries, and roughly 16–18 m of process length with feeding and pelletizing. Layout and foundation drawings come 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.

SE-200 single screw extruder — the short version
Note on SE-200 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.
