KTE-75 Twin Screw Extruder
KTE-75: the 71 mm base-class twin screw extruder, 110–132 kW, 300–800 rpm, 300–500 kg/h — the standard-torque workhorse of the mid-range. A reference KTE-75 twin screw extruder page from Kerke.

The KTE-75 is the 71 mm platform at standard torque (2×1,050 N·m): 300–500 kg/h of general compounding and masterbatch at mid-range economy. It shares screw platform and barrels with the 75B and 75D, so the line can grow by re-elementing long before it grows by replacing.

Parameters
| Model | Dia. (mm) | Speed (rpm) | Motor (kW) | Torque (N·m) | Output (kg/h) |

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 75 family: base KTE-75, KTE-75B (2×1,530 N·m, 300–800 kg/h) and KTE-75D (2×2,100 N·m, 500–1,000 kg/h). Below it, the KTE-65B covers the same output band from below with a smaller screw; above it, the KTE-85B starts the large-bore class.
What it runs
Duties: filler masterbatch 70–85%, colour masterbatch in volume, PP/PE/ABS compounding, carrier production, and recompounding lines where 350–450 kg/h pays the rent. Severity above 85% filler or glass fibre belongs to the 75D.

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-75 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
KTE-75 or KTE-75B for a 400 kg/h line?
At a steady 400 kg/h on benign materials the base 75 is priced right. If the forecast touches 600–800 kg/h or the filler grade varies, the 75B's extra torque pays for itself in uptime.
What L/D is typical on the 75?
40–48 for filled compounds with side feeding; 32–36 for straightforward masterbatch. The 75 frame handles up to 60 for reactive duties, but that is a specialist build.
Can the 75 take a two-stage configuration?
Not as itself — two-stage means a separate SE single screw stage. The KTE-75B pairs with the SE-180 as the KTE-75B / SE-180 line for 85–90% filler and HFFR work.
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-75 twin screw extruder — the short version
Note on KTE-75 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.
