KTE-65B Twin Screw Extruder
The KTE-65B twin screw extruder is our most exported model: 62.4 mm, 2×860 N·m, 200–450 kg/h — B-class economy with the headroom most masterbatch plants actually need.

The KTE-65B is the volume seller of the range: 62.4 mm screw, 90–110 kW, 2×860 N·m at 500–600 rpm, 200–450 kg/h reference output. It covers filler and colour masterbatch up to 85%, general compounding and recompounding at the best price-to-output ratio in the KTE line-up.

Parameters
| Model | Dia. (mm) | Speed (rpm) | Motor (kW) | Torque (N·m) | Output (kg/h) |
|---|---|---|---|---|---|
| KTE-65B | 62.4 | 500–600 | 90–110 | 2×860 | 200–450 |
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
Inside the 65 family: the base KTE-65 below it (2×720 N·m, 100–350 kg/h) and the KTE-65D above it (2×1,530 N·m, 350–600 kg/h). The 65B is the middle choice — same 62.4 mm screw platform, B-class gearbox, and the output band where a growing masterbatch plant lives for years.
What it runs
Bought for: filler masterbatch at 75–85% CaCO3/talc with side feeder, colour and white masterbatch, PP/PE compounding, masterbatch carriers, and recompounding. When the duty moves past 85% filler or into glass fibre, the same platform continues as 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-65B 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
What output does a KTE-65B really deliver?
Reference 200–450 kg/h on the stated material family — 85% filler masterbatch lands near the middle, colour masterbatch near the top. We quote a guaranteed figure only after a trial with your own powder, because filler grade and bulk density move output by ±15%.
65B or 75B — how do I decide?
Target output decides: up to ~450 kg/h the 65B is the cheaper per-kg/h choice; from 500 kg/h the 75B (300–800 kg/h) takes over. Torque per screw is close (2×860 vs 2×1,530 N·m), so severity is not the deciding factor between them.
What pelletizing goes with the 65B?
Water ring for 70–85% filler masterbatch, strand below that and where pellet shape is sold, air-cooled hot face for PVC-type compounds. The pelletizer is a module; it can be changed later without touching the extruder.
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-65B twin screw extruder — the short version
Note on KTE-65B 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.

Every quotation lists the wear package as a separate line, so its cost is visible from day one.
