Quick answer

The KTE-135D is the top of the range: 135 mm screw, 2×7,800 N·m, up to 1,000 kW, 1,500–4,000 kg/h. It is built for the duties no other configuration can carry at volume — 90% filler masterbatch at 2,000 kg/h+, glass-fibre compounds at plant scale, and reactive systems with real tonnage.

Parameters

KTE-135D	135	500–800	500–1000	2×7800	1500–4000

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 last step of the ladder: KTE-135B shares the bore with B-class torque, the KTE-95D shares the torque class with a smaller bore. Nothing in the KTE range sits above it; larger duties are handled by parallel lines, not by a bigger screw.

What it runs

Duties: 90% CaCO₃/talc masterbatch at 2,000 kg/h+, glass-fibre PP and PA at 1,500 kg/h+, XLPE and HFFR cable compound mega-lines, and reactive extrusion (MAH grafting, TPU) where chemistry and tonnage must coexist.

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-135D 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

Who actually needs a KTE-135D?

Plants whose hardest recipe and largest volume arrive together: 90% filler at two tonnes per hour, or glass fibre at 1,500. Below that combination, a 95D or 135B is the rational machine.

What does installation of a 135D involve?

Foundation drawings, crane planning for the gearbox set, medium-voltage supply, and typically 3–5 weeks on site including commissioning. We send the engineer; the record ships with the machine.

How is spare-part strategy handled at this scale?

A recommended spare set ships with the line, and standard-size elements dispatch from our workshop in 24–48 hours. At this torque class the wear package is engineered per formulation, not picked from a shelf.

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-135D twin screw extruder — the short version

Note on KTE-135D 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.
