SE-150 / SE-150 Two-Stage Recycling Line
SE-150 / SE-150 two-stage single screw line: 400–800 kg/h for film and woven-bag recycling — the mid-size answer for washed agricultural and packaging scrap. A reference SE-150 SE-150 two-stage single screw extruder page from Kerke.

The mid SE/SE: two 150 mm screws, 400–800 kg/h, for film and woven-bag streams at commercial rate. Compaction on stage one, degassing and pressurization on stage two — the configuration that keeps IV and moisture specifications on washed material.

Parameters
| Configuration | Stage 1 | Stage 2 | Output (kg/h) | Feed |
|---|---|---|---|---|
| SE-150 / SE-150 | 150 mm | 150 mm | 400–800 | Film, woven bag |
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
Middle of the family: the SE-120 / SE-120 below (200–400 kg/h), the SE-180 / SE-180 above (800–2,000 kg/h). If the feed is dense regrind rather than film, a single SE-150 does the job in one machine at lower cost.
What it runs
Duties: washed agricultural film, woven-bag bales after shredding, printed packaging scrap, and PE/PP mixed streams where venting decides pellet quality.
Configuration options
The SE-150 / SE-150 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 feeding system does this line need?
A compacting (force) feeder with metal detection, fed by shredding and pre-drying. Feeding is sized with the line because film bulk density — 80–150 kg/m³ — is what the first stage is really there to fix.
Where does the vacuum sit?
On stage two, typically single or double vacuum vent depending on print and moisture load. Stage one's job is melt and compact; venting too early pulls fog, not vapour.
What pelletizing suits the SE-150/SE-150?
Water ring for film grades going back into extrusion, strand where pellet shape is sold, underwater for dense dust-free product. The choice follows the customer's downstream process.
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 SE-150 two-stage single screw extruder — the short version
Note on SE-150 SE-150 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-150 SE-150 two-stage single screw extruder: the data on this page was last verified on our own test line in Nanjing.
