Plastic recycling equipment by co-extrusion system, composed of two twin corotating screw extruders BAUSANO MULTIDRIVE – 4 X 2 system, Series 92-BGP-5031.
Year 1.985. - Their general condition is Excellent, always with a permanent and impeccable maintenance.
Suitable for recovered materials from thermoplastics like HDPE, LDPE, PS, PP, UPVC, and similars.
Depending on the types of plastics and their specific weight, the productions working in Co-Extrusion, would be around 1.500 to 2.000 kg/h.
Can also work only with the main extruder, in which case the production would drop to 30/40% less.
The MULTIDRIVE transmission system, with corotating screws and 4 efficient motors, is a reference technology in the extrusion world guaranteeing the highest quality and precision, even in large production volumes.
By distributing the movement in four different points, this MULTIDRIVE system reduces considerably the torsional stress to a quarter, which prolongs the life of the shafts and the gearbox, guaranteeing greater durability, improving the reliability of the extruder and achieving significant energy savings.

OPTIONAL EQUIPMENTS
We describe some optional equipment, totally manufactured in INOX and can be very interesting depending on the composition and final product to be manufactured.

Corresponding to the main extruder:
1) To install at the Degasser.
Filtering system direct to the pump, composed of two stainless steel tanks with three bag filters each unit and self-cleaning by air pressure jet.

2) To install in the forced feeding:
a) Dosing systems: composed of 2 independent hoppers, each one with automatic dosing systems direct to the forced feeding hopper.
b) It can also be supplied with a dust collection system at the inlet of the forced feeding with a filter of 10 self-cleaning bags.

3) To install at the Vacuum Pump:
Gas filtering system, installed at the same outlet of the vacuum pump, consisting of 2 self-cleaning bag filters with 3 bag filters each.

Corresponding to Co-extruder:
4) To install in the forced feeding:
Accumulation hopper with volumetric feeding and continuous dosing system with automatic controlled closure with direct fall to the forced feeding hopper.
