The COMPEO LAB test machine, which has the same functions and specifications as the COMPEO series, is compact yet compatible with all applications.
COMPEO LAB enables efficient prototyping and testing with a discharge capacity of 50 to 100 kg/h. The Buss kneader, due to its thoughtfully designed structure, can provide the same shear force across machines of different sizes, as long as the screw configuration and screw rotation speed are the same. Therefore, by introducing this COMPEO LAB as a pilot line, scaling up to large production machines becomes easy.

Company information
Buss AG, headquartered in Switzerland, has been manufacturing and selling continuous kneading extruders that play a crucial role in various compounding processes involving chemical materials such as plastics and rubber, as well as food, for over 70 years. Buss was the first in the world to introduce a unique continuous kneading extruder using the reciprocating motion of a single-screw, and has long been known as the Buss Ko-Kneader. It has gained immense trust from customers who require precise temperature control and produce shear-sensitive materials. This has enabled it to thrive in various chemical manufacturing settings, including PVC, polypropylene, PET, thermoplastic elastomers, XLPE, flame-retardant cables, masterbatches, powder coatings, and toners. Together with a global sales network and partners, Buss provides reliable and efficient technology along with top-class after-sales service.
