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

Company information
Busch 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. Busch was the first in the world to introduce a unique continuous kneading extruder that utilizes the reciprocating motion of a single-screw, and has long been known as the 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 environments, including PVC, polypropylene, PET, thermoplastic elastomers, XLPE, flame-retardant cables, masterbatches, powder coatings, and toners. Together with a global sales network and partners, it provides reliable and efficient technology along with top-class after-sales service.
