KNE-1200 Kneader Compounding Line
KNE-1200: kneading section plus SE-200 discharge, 800–1,200 kg/h — the tonnage size for 88–90% CaCO3 filler masterbatch and carbon black at scale. A reference KNE-1200 kneader compounding extruder page from Kerke.

The largest kneader line we build: 800–1,200 kg/h, discharge through an SE-200. Built for filler masterbatch at 88–90% CaCO3 — a loading a twin screw cannot hold without turning the carrier yellow — and for carbon black masterbatch above 40% at tonnage.

Parameters
| Line | Output (kg/h) | Discharge screw | Pelletizing | Typical product |
|---|---|---|---|---|
| KNE-1200 | 800–1,200 | SE-200 | Underwater or air-cooling die face | Carbon black masterbatch > 40%, tonnage |
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
Top of the family, with the KNE-800 below it at 400–800 kg/h. Above 1,200 kg/h the plant answer is a second line rather than a bigger kneader: the heat-exchange surface of the kneading section, not its motor, is what limits the loading.
What it runs
Duties: 88–90% CaCO3 and talc filler masterbatch, carbon black above 40% at tonnage, and heavy colour concentrates where a visible wet-out stage decides dispersion.
High Filler Masterbatch Line
Above 85% the melt stops behaving like a polymer: it will not take shear heat, and one machine cannot both wet out the…
Black Masterbatch Extruder Line
Carbon black at 40% costs 20–25% of the output of a general colour masterbatch on the same machine — dispersion eats t…
Configuration options
A KNE-1200 line is quoted as kneading section + discharge screw + pelletizer, because the three only work as a set. The kneading section is self-cleaning and jacketed, with a heat-exchange surface sized to the filler level; the discharge screw is sized from the kneading capacity per hour, not from motor kW. Options: discharge screw (SE-120 to SE-200), cutting system (water-ring hot-face, air-cooling die face, underwater or strand) and vacuum devolatilisation at the discharge where the mineral carries moisture.
FAQ
What sits above the KNE-1200?
Nothing in this line — 1,200 kg/h is the ceiling. Above it plants run a second kneader line, or move plain filling duty to a two-stage twin screw; the duty profile decides and we model both before quoting.
How does it hold 90% filler?
The kneading section wets out the mineral with a large heat-exchange surface and a short, near-plug-flow residence time, so heat leaves as fast as it is generated; the discharge screw then adds pressure without adding mixing.
Is the discharge screw configurable?
SE-200 as standard, SE-180 where a lower output with higher die pressure suits the die. It is fixed at quotation because the screw is matched to the kneading capacity, not chosen afterwards.
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.

KNE-1200 kneader compounding extruder — the short version
Note on KNE-1200 kneader compounding 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.
