Pellet and compound downstream

The screen changer allows reusing, through the extrusion granulation line, all the plastic materials from scraps or post-consumer – such as PVC, PE, PP, PC and ABS – removing any contaminants. Designed for the special needs of companies operating in plastic material regeneration, the Bausano automatic hydraulic screen changers can be installed directly on the terminal of the barrel and connected to all our standard granulation heads. A flashing and acoustic alarm will be activated whenever a change of the screen is required.

Die heads or pelletizing units are used in strand pelletizing systems for extrusion of granules. Bausano granulation heads are used for the production of thermoplastic granules, both virgin and recycled, obtained from work scraps. Designed to achieve the optimal distribution on the die plate and to facilitate opening and cleaning operations, reducing the machine downtime to a minimum.

The Bausano plastic pelletizing lines are composed of a lateral air cutter, complete with guard for forced air circulation and soundproofed fan. The cut granule is conveyed through stainless steel pipes up to the cooler where a cooled cyclone with double air gap separates air and fumes. This cutter has the possibility of adjusting both the length and the diameter of the granule.

The frontal air cutting unit is a cutter with non coaxial cutting blades in relation to the granulation head. This construction feature allows the blade surface temperature to remain low, preventing the decomposition of any processed material residues. The adjustment of the cutting of the granule is ensured by a double motorization both managed by a control PLC which allows the synchronization of the speed of the cutter and the roller.

Granule cooling is carried out on holed stainless steel sheet surfaces through a forced air circulation generated by vertical flow valves, fitted in the machine base. Wall-mounted filters, fitted outside the base, ensure an air flow with no contamination. The alternating movement of the surfaces is generated by proper counter-rotating mass vibrators, allowing a uniform distribution of granules, with subsequent optimisation of the useful cooling surface.

Specially used for recycling polyethylene, polypropylene and other types of polymers, we offers a series of submerged or liquid ring water cuts, able to satisfy the most varied needs of its customers. From the cutter control console it is possible to set the automatic and manual operation of the synchronism between the pulling and the cutter without modifying directly on its extruder adjustment parameters.
