Quick answer

The SE-65 covers 60–150 kg/h at 18.5–22 kW: small recycling streams, profile and strap extrusion, and pelletizing where the budget is real but the volume is not yet. L/D 25–30 with forced feeding available for pre-broken regrind.

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

Second step of the SE family: the SE-50 below for trials, the SE-90 (150–300 kg/h) above as the first serious recycling size. For film and woven-bag scrap at volume, the two-stage SE-120 / SE-120 line is the proper tool.

What it runs

Duties: clean regrind pelletizing, PP strap and small profiles, masterbatch let-down, and edge-trim reprocessing for converters who generate more scrap than an SE-50 can chew.

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-65 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

Can an SE-65 run washed flake?

Yes with a forced feeder and a screen changer — washed PE/PP flake is a normal duty at 80–120 kg/h. Drying upstream matters more than the machine choice at this size.

SE-65 or SE-90 for a growing recycling operation?

If the feed is clean and predictable, the SE-65 is cheaper per kg/h. If the stream is mixed and the schedule varies, the SE-90's 150–300 kg/h band absorbs the peaks without overtime.

What L/D suits pelletizing on the 65?

28 for clean regrind, 33 when venting or heavier duty is planned. The L/D is fixed at order; barrels are modular but the frame length is not retro-fittable.

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-65 single screw extruder — the short version

Note on SE-65 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.
