SE-180 / SE-180 Two-Stage Recycling Line
SE-180 / SE-180 two-stage single screw line: 800–2,000 kg/h for woven bag and heavy film — the largest SE/SE, built for industrial recycling tonnage. A reference SE-180 SE-180 two-stage single screw extruder page from Kerke.
Quick answer
The heavy SE/SE: two 180 mm screws, 800–2,000 kg/h, for woven-bag and heavy-film streams at industrial rate. It is the machine for recyclers whose feed arrives in bales and whose pellets leave in containers.

Parameters
| Configuration | Stage 1 | Stage 2 | Output (kg/h) | Feed |
|---|---|---|---|---|
| SE-180 / SE-180 | 180 mm | 180 mm | 800–2,000 | Woven bag, heavy film |
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 SE/SE family: the SE-150 / SE-150 below (400–800 kg/h). At this scale the line is a plant — shredding, washing, feeding, two stages, filtration, pelletizing — and the quotation is written accordingly.
What it runs
Duties: PP woven bag at 1,200–1,800 kg/h, heavy PE film and industrial packaging scrap, agricultural film at industrial rate, and mixed rigid/film streams with robust pre-sorting.

Configuration options
The SE-180 / SE-180 line is built around one idea: split melting from degassing so neither stage is asked to do both. Stage one runs deep-flighted and half-full to melt and compact; stage two runs shallow and full to pressurize the die and hold vacuum. Options at quotation: compacting (force) feeder with metal detector for film bales, double-station hydraulic screen changer, and the vent layout — single atmospheric plus vacuum, or double vacuum for heavily printed film.
FAQ
What decides between one SE-200 and this two-stage line?
Feed density and cleanliness: dense, clean regrind takes the single SE-200; film, bag and contaminated streams need the two-stage architecture to hit both output and quality targets.
How is ink and odour handled on printed scrap?
Double vacuum venting on stage two plus, where analysis demands it, a hot-wash upstream. The trial on your scrap decides the configuration before the quotation.
What is the installation footprint?
Plan 18–22 m of process length with feeding and pelletizing, 250 kW-class installed power, and a building that accepts bale logistics on one end and silos on the other.
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 SE-180 two-stage single screw extruder — the short version
Note on SE-180 SE-180 two-stage 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.
Note on SE-180 SE-180 two-stage single screw extruder: the data on this page was last verified on our own test line in Nanjing.
