KTE-95B / SE-200 Two-Stage Extruder
The KTE-95B SE-200 two-stage extruder (also written KTE-95B / SE-200): 93 mm twin screw + 200 mm single screw, 1,000–2,000 kg/h — the largest KTE/SE line, built for high-filler and cable compound at industrial scale.

Parameters
| Configuration | Stage 1 (twin screw) | Stage 2 (single screw) | Output (kg/h) | Typical product |
|---|---|---|---|---|
| KTE-95B / SE-200 | 93 mm | 200 mm | 1,000–2,000 | High filler, cable compound |
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
Final step of the KTE/SE ladder: KTE-75B / SE-180 below (700–1,200 kg/h). Where severity outgrows the B-class twin screw section, the honest alternative is a parallel line rather than a bigger pairing — the SE-200 stage is already the largest we build.
What it runs
Duties: high-filler masterbatch (85–90%) at 1,200–1,800 kg/h, cable compound for continuous vulcatization feed, stone-paper and WPC-type high-loading compounds, and devolatilization-heavy duties where the twin screw vent must strip solvent or moisture at industrial rate.

Configuration options
The two stages are ordered as one line but do different jobs, and the quotation reflects that: stage one gets the mixing geometry and the wear package, stage two gets a deep-flighted low-shear screw built only to meter and pressurize. Options that matter on a KTE-95B / SE-200 line: vacuum degree on the twin screw vent (−0.06 to −0.09 MPa), water-ring versus air-cooled hot-face pelletizing on the SE stage, and whether the SE discharge runs at fixed speed or follows the twin screw through a gravimetric loop.
FAQ
What decides between this and a KTE-95D single machine?
Pressure versus mixing: if the product needs low-shear finishing after heavy mixing, the SE-200 stage wins; if the difficulty is torque inside the mixing itself, the 95D wins. The trial separates the two in a week.
How is the 2,000 kg/h top end reached?
On benign, free-flowing products at the top of the filler band. At 90% loading plan 1,200–1,600 and let the trial put the exact figure in the quotation.
What redundancy should a plant plan at this scale?
A recommended spare set (screw elements, SE stage liner, screen packs) ships with the line, and standard parts dispatch in 24–48 hours. Most 95B/SE-200 operators hold one shift's worth of wear parts on site.
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-95B SE-200 two-stage extruder — the short version
Note on KTE-95B SE-200 two-stage 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.
