The production line of nylon modified granulation turnkey project delivered by Coperion to LANXESS was officially put into operation

Specialty chemicals company LANXESS has added a turnkey production line for nylon 6, nylon 66 and PBT (polybutylene terephthalate) designed and delivered by Coperion at its Krefeld-Uerdingen plant.
The blending modification and granulation of glycol esters) helped LANXESS to significantly increase the existing production capacity
.

Coperion's blending and modification production line for LANXESS covers a complete turnkey solution from design to commissioning
.
From modern raw material feeding, to conveying, mixing, granulation and screening technology, Coperion seamlessly integrates every process step in the system and logically integrates them into one system , which laid the foundation for the fully automated production of this blending and modification production line
.
With a very short equipment installation and commissioning process, the efficient production capacity of the production line can be fully utilized
.

Thanks to Coperion's intelligent blending and compounding plant solutions, LANXESS is able to produce high-quality nylon compounded products at large capacity and serve customers
.

In addition, the production line designed by Coperion for LANXESS fully optimizes the spatial layout of the factory floor, which not only reduces the walking distance of operators, but also ensures that each unit and individual equipment has sufficient space for operation and maintenance.

.

Each core component and individual equipment of this complete solution is developed and manufactured by Coperion itself, including a ZSK 92 Mc18 high-performance twin-screw extruder, which can reach super 18 Nm/cm3.
High specific torque plays a key role in increasing the yield of nylon reinforced modification
.
This ZSK twin screw extruder is also equipped with ZS-B twin screw side feeder and ZS-EG side devolatilization device
.
Coperion has also developed the SK92 head specially for nylon modification for this purpose
.
With its intelligent heating/cooling function, a very uniform temperature distribution is achieved, and even at high output, the strip can be extruded completely uniformly over the entire head width, avoiding coiling and stripping
.
The optimized geometric flow channel can gently extrude the modified nylon melt, reduce the temperature rise during extrusion, and then improve the final blending modification quality
.

In the new SK92 design, the head template can be changed easily and quickly with just a few simple manual operations
.
The fully automatic strand pelletizing system provided by Coperion pelletizing technology company has made a very important contribution to the automatic operation of the whole system
.
It can automatically pull the extruder strands through the cooling water tank and downstream conveyor belt to the feed port of the SP700 HD pelletizer
.
The entire start-up process can be fully automated thanks to the automated tie and reconnection of broken strips
.
In this way, there is almost no loss in the production process of the product, and the entire production process is not interrupted
.
