KTE-65 Twin Screw Extruder

KTE-65: the 62.4 mm standard-torque twin screw extruder at 100–350 kg/h — the cost-optimised base model of the most common screw size we build. A reference KTE-65 twin screw extruder page from Kerke.

Quick answer

The KTE-65 is the base configuration of the 65 platform: 500 rpm, 75–90 kW, 2×720 N·m. It covers general compounding and masterbatch up to roughly 300 kg/h at the lowest price per kg/h in the range, and it accepts every barrel module and element of the 65-series B and D machines.

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

The 65 family is the centre of the KTE range: the base KTE-65 for standard duty, the KTE-65B (2×860 N·m, 200–450 kg/h) for fuller schedules, and the KTE-65D (2×1,530 N·m, 350–600 kg/h) for high filler, glass fibre and 600 kg/h ambitions. The same 62.4 mm screw and barrel set fits all three.

What it runs

Normal duties: filler and colour masterbatch to 80% loading, PP/PE/PS compounding, masterbatch carrier production, recompounding of regrind where torque demand is modest. Above 85% filler or with glass fibre, move to the 65D.

Configuration options

Every KTE ships as a building-block system: screw elements on splined shafts, barrel modules that accept side feeders, liquid injection and vacuum vents, so the geometry is set by the formulation rather than fixed at the factory. Three choices define a KTE-65 quotation: the L/D (32–36 for simple filling, 40–48 with side feed and devolatilization, 52–60 for reactive duties), the wear package (standard 38CrMoAlA or bimetallic liner with PM/HIP elements where CaCO3, talc or glass fibre grind), and the pelletizing head (strand, water ring, air-cooled hot face or underwater — matched to the polymer, not to the model number).

FAQ

Why choose the base KTE-65 over the 65B?

Price per kg/h. If your formulation is a straightforward filler or colour masterbatch under 80% and the target is 150–300 kg/h, the base model's 2×720 N·m is sufficient and the saving is real.

Can a KTE-65 be upgraded to B or D later?

The gearbox is the differentiator, so upgrading means a gearbox and motor change on the same frame — possible but rarely economic. Better to size the class correctly at purchase; the screw set and barrels stay interchangeable either way.

What L/D do you recommend on the 65?

32–36 for filling, 40–48 with side feeder and vacuum, 52–60 for reactive work. The 65 frame carries all three; the choice follows the formulation, and we set it on the trial.

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.

KTE-65 twin screw extruder — the short version

Note on KTE-65 twin 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.
