Quick answer

The KTE-135B is the volume flagship of the B class: 135 mm screw, 2×4,800 N·m, 1,500–3,000 kg/h. It exists for masterbatch and compounding plants where a single line must replace two mid-size ones — one machine, one operator team, one quality record.

Parameters

**Table 1.** KTE-135B — reference parameters. Full Co-rotating twin screw KTE range on the series page.
Model	Dia. (mm)	Speed (rpm)	Motor (kW)	Torque (N·m)	Output (kg/h)
KTE-135B	135	500–600	315–500	2×4800	1500–3000

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

Bore-wise it tops the B class: the KTE-95B below shares its torque; the KTE-135D above shares its bore with 2×7,800 N·m. Between the 95 and 135 classes there is no intermediate bore — the decision is usually 95D versus 135B on duty severity.

What it runs

Duties: filler masterbatch at 1,500–2,500 kg/h, colour masterbatch mega-batches, polyolefin compounding at plant scale, and carrier resin production where a single grade runs for weeks.

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-135B 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

135B or two 65B lines?

One 135B replaces two mid-size lines with less labour, floor space and quality variance — at the cost of flexibility when the order book splits into small batches. Plants with both patterns often buy one large and keep a 65 class for short runs.

What pelletizing carries 3,000 kg/h?

Underwater or large water-ring die faces; strand at this output means too many strands to supervise. The pelletizer choice is fixed early in the project because downstream layout follows it.

How long does a 135B project take?

45–70 working days for the standard configuration, plus commissioning. Large-bore lines ship with a full test-run record from our own floor — with material, not just a dry spin.

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-135B twin screw extruder — the short version

Note on KTE-135B 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.

Note on KTE-135B twin screw extruder: the data on this page was last verified on our own test line in Nanjing.
