Product overview strand pelletizing accessories

Die head

Strand die heads or strand pelletizing units are used in strand pelletizing systems for extrusion of strand profiles. SG-C series die heads have been specifically developed for applications in masterbatch, compounding, and recycling processes. They are used downstream of single [...]

Application: Compounding • Recycling • Wood flour

Dry cut strand pelletizing

In dry cut strand pelletizing, the plastic melt is routed to the die head. It distributes the melt into dies. The pressure in the die plates creates polymer strands that have to be conveyed to the cutting rotor. For water-sensitive polymer strands, an EBG single-belt pelletizing system is ideal. Other polymers can be transported via a constantly temperature-controlled KW cooling tank. This is followed by the air knife system, featuring the JV air knife series or the SE vacuum air knife. The hot air knife (HAK) is a hot air blower for the removal of melt residues, outgassing residues, and filler deposits directly on the die head.

The PWA process water treatment system filters, maintains temperature, and continuously rolls process water in compound and masterbatch production. A heat exchanger separates the contaminated process water from the primary cooling water circuit. The PWA process water treatment can be integrated into the base frame of the KW cooling trough or placed externally.

Following the dry cut and the wet cut, a FRU/SRK screen machine can be connected. The screen machine screens out skewers, husks, or chains as well as oversized or multiple grains and dust.
