Quick answer

The KTE-75B is the mid-range workhorse: 71 mm screw, 132–160 kW, 2×1,530 N·m, 300–800 kg/h. It runs 75–85% filler masterbatch in volume, handles colour masterbatch at hundreds of kg/h, and pairs with the SE-180 as a two-stage line when the duty crosses 85%.

Parameters

**Table 1.** KTE-75B — 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-75B	71	500–600	132–160	2×1530	300–800

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

In the family: base KTE-75 below, KTE-75D above (2×2,100 N·m, 500–1,000 kg/h). Against the smaller KTE-65B the 75B buys roughly double the output band; against the KTE-85B (550–1,000 kg/h) it is the smaller investment with the same gearbox class.

What it runs

Bought for: filler masterbatch plants moving past 500 kg/h, black and colour masterbatch in commercial volume, PVC and cable compounds where the two-stage variant takes over, and toll compounding where formulation variety argues for building-block flexibility.

Why Air-Cooling Hot-Face Cutting

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-75B 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

75B or two-stage KTE-75B / SE-180?

Formulation ceiling decides: up to 85% filler a single 75B is right; at 85–90% or on PVC/HFFR the two-stage pairing keeps output stable while viscosity climbs. The twin screw section is identical — the SE stage is additive.

What does a 75B cost to run per kg?

Energy per kg on filled masterbatch typically lands in the 0.25–0.35 kWh/kg band on commissioning records, driven by filler level and L/D. The trial report shows the measured figure for your grade before you commit.

Is 800 kg/h real on the 75B?

Reference band 300–800 kg/h — the top of the band belongs to low-loading, easy-flowing products. A realistic plan for 85% filler masterbatch is 500–650 kg/h; we put the number in writing after 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-75B twin screw extruder — the short version

Note on KTE-75B 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.
