Fully automatic transfer from die head to pelletizer

Coperion's automatic strand conveying system ASC ensures fully automatic transfer from die head to pelletizer. Designed to work in conjunction with Coperion's two largest strand pelletizers, the SP 500 HD and the SP 700 HD, this conveyance system is likewise available in two sizes: the ASC 500 for throughput rates of up to 3.5 t/hr and the ASC 700 for up to 5 t/hr.

The conveyance system automatically guides the extruded strands via a cooling water chute and downstream conveyor belt into the feed mechanism of the pelletizer. A likewise automatic start-up mechanism facilitates the start-up operation, while any possible machine malfunctions caused by broken strands are avoided by the system's ability to rethread the strands.

The new SK92 die head has been developed specially for high throughput rates. Homogeneous heating/cooling ensures completely uniform extrusion of the strands across the entire width of the extrusion die. The die head is distinguished by its optimal rheology and efficient heat transfer, providing maximum possible throughput while ensuring gentle handling of the product. This feature makes the SK92 die head ideally suited to the increased throughput capabilities of the ZSK Mc¹⁸ extruder series.

The new automatic strand conveying system may be used for a broad spectrum of materials. It is equipped as standard with a vertical adjustment permitting different points of strand placement on the water chute depending on the material being processed.

The advantages at a glance:

Automatic strand conveying system without manual operation

Self-lacing of broken strands avoids any possible machine malfunctions

Reduced complexity of the system and the low rate of wear

Specially developed die head ensures completely uniform extrusion of the strands across the entire width of the extrusion die

The modular design permits flexible and rapid adaptation to the requirements of the process

Maximum operating flexibility due to adjustable cooling length

Strand pelletizing ensures an extremely gentle treatment of the product, as it operates with much lower pressures
