Primo 200E is Automatik Plastics Machinery’s new single-side mounted dry-cut strand pelletiser with an extra-large cutting width of 200mm. The short unguided length between the feed rolls and the cut is said to enable good straight cutting of both hard and very soft plastic strands. The Primo 200E is particularly suitable for compounding thermoplastics, for functional and additive masterbatch production and for the production of colour concentrates up to a line throughput rate of 1.5t/h.
Highlights of the pelletiser are its cutting tool sets for hard, abrasive and soft, flexible plastics. The pellet dimensions can be quickly changed by means of an optional automatic pellet length adjuster. This is done using a second drive motor for the feed mechanism with an integrated speed control.
When processing abrasive products and at high production temperatures, the Primo 200E can optionally also be equipped with a separately driven, highly wear-resistant metal feed roll instead of the standard elastomer feed roll.
Another feature of the machine is that the feed geometry is designed without major deflections, so the plastic strands are not subjected to pre-tensioning prior to cutting. This means that even highly fragile polymers such as polystyrene or highly filled masterbatches can be pelletised in high qualities, virtually dust free.
