SE-180 Single Screw Extruder

SE-180 single screw extruder: 180 mm, 132–185 kW, 800–1,500 kg/h — the heavy recycling size behind woven-bag bales and high-volume regrind.

Quick answer

The SE-180 is the heavy end of standalone recycling: 800–1,500 kg/h at 132–185 kW. It is built for woven-bag and heavy film streams, and it is the discharge size of the KTE-75B / SE-180 two-stage line and the KNE-800/KNE-1200 kneader lines.

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-150 (500–1,000 kg/h) and the SE-200 (1,000–2,000 kg/h). Its two-stage roles: second stage of the KTE-75B/SE-180 line, discharge for mid/large kneaders, and the large stage of the SE-180 / SE-180 line for heavy film.

What it runs

Duties: woven-bag and heavy-film recycling at 1,000 kg/h class, agricultural film after washing, PVC and cable compound at volume, and kneader discharge for high-viscosity products.

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-180 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 feeding does woven-bag scrap need on an SE-180?

A compacting feeder with metal detection and pre-shredding — the screw cannot meter loose bales. Feeding is half the project at this size; the quotation treats it that way.

Is the SE-180 oversized for plain regrind?

If the stream is dense and clean and the forecast is under 800 kg/h, the 150 is the better price. The 180 earns its cost on low-bulk-density input, where feeding — not melting — sets the rate.

What vent configuration suits printed film?

Double vent (atmospheric plus vacuum) at L/D 33 is the standard answer for printing inks and moisture; severely printed material may still justify a wash upstream — we model both costs.

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-180 single screw extruder — the short version

Note on SE-180 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.
