End of line systems for pelletizing

Bausano designs and manufactures complete solutions for plastic processing, supporting the extrusion process through to the pelletizing end of line. The integrated approach enables each phase to be managed in a coordinated way, from melt filtration to pellet cutting and cooling.
 The end of line solutions are developed to ensure process stability, constant product quality and operational continuity, even with complex formulations and sensitive materials. A system designed to meet the needs of the compounding industry, with configurations adaptable to different materials and production volumes.

Suitable for compounding, masterbatch and pelletizing operations, the pelletizing die head integrates downstream of Bausano counter rotating twin screw extruders or filtration systems. It is compatible with different formulations and process parameters, supporting an efficient transition to the cutting phase.
 The structure is designed to ensure uniform distribution of the molten material on the plate, with stable and efficient flow dynamics. The flow channel design reduces stagnation areas, making material changes, cleaning and maintenance faster, with reduced machine downtime.

The screen changer enables the reprocessing of a wide range of thermoplastic materials, such as PVC, PE, PP, PC and ABS, in compounding and extrusion lines. It removes impurities and contaminants continuously, improving the quality of the melt and of the final pellet.
 Installed directly at the barrel outlet, it is compatible with all standard pelletizing die heads. A visual and acoustic alarm system signals when the filter needs to be replaced, ensuring operational continuity and process safety.

The frontal air cutter is designed for processing thermoplastic materials sensitive to temperature and mechanical stress. The cutting system operates directly on the pelletizing plate, with knives mounted on self centering rotors that ensure constant alignment and cutting precision.
 Forced air cooling keeps operating temperatures low, preserving material integrity and limiting the formation of residues and dust. Pellets are conveyed through cooled ducts to the cooling unit, ensuring thermal stability and process continuity.

The lateral cutter is designed to transform extruded strands into pellets with uniform dimensions. Cutting is performed by rotating knives mounted on a rotor placed eccentrically in relation to the pelletizing plate, a solution that ensures precision and process stability even with materials sensitive to temperature and mechanical stress.
 The system integrates forced air cooling and pellet conveying through stainless steel pipes to the cooling unit, with controlled separation of air and vapors.

The L4/M frontal air cutter is a compact unit designed for precise pellet cutting in extrusion lines for pelletizing. The system integrates three blades mounted on a self centering ball joint, which maintains constant pressure on the pelletizing head and reduces dimensional variations in the pellet.
 The unit is driven by a 2.2 kW motor, controlled through an inverter integrated into the extruder panel, for accurate adjustment of cutting speed according to the material and process conditions. Forced air cooling, enclosed in a dedicated cover, maintains stable thermal conditions in the cutting area.
 The sliding base structure with guides enables fast and safe cleaning operations. Pellet transfer takes place through galvanized launch pipes and cooled stainless steel elbows, ensuring controlled thermal management through to the cooling unit.

The pellet cooler is designed to ensure uniform product conditioning and high thermal efficiency. The system includes a stainless steel collection cyclone with integrated filter and a self cleaning vibrating tray.
 Cooling takes place through perforated surfaces and forced air circulation, with flow rate adjustable by inverter. Uniform pellet distribution and controlled separation of fine particles help ensure dimensional stability and constant quality.
