Máquinas de pelletizing para reciclaje de plásticos

In supplier listings, this term can refer to a complete system that converts prepared plastic into pellets through feeding, extrusion, melt treatment, cutting and cooling. Confirm which modules are included in the quotation, because pelletizer can also mean only the pellet-cutting unit.

The extruder melts, mixes and conveys the polymer, with venting or vacuum degassing where configured. A pelletizer cuts material at the die face or cuts cooled strands into pellets. A complete recycling line combines these functions with the required feeding, filtration, cooling and handling equipment.

Low-density film often needs a cutter-compactor, agglomerator or other assisted feeding arrangement. Single-screw extrusion and water-ring cutting are common options, but feeding and cutting are separate configuration choices. Select them together using the feed moisture, printing, contamination, melt behaviour and required pellet quality.

Contaminated scrap may need sorting, washing and drying before extrusion; washing alone does not separate every mixed polymer. Clean, sorted production scrap may need less pretreatment. Define inlet moisture for the chosen process, especially for the featured PET single-screw route, which requires properly dried flakes.

Consider twin-screw recycling when prepared material needs stronger melt homogenization or devolatilization. For additives, fillers or modified recycled compounds, consider a compounding configuration with appropriate dosing and mixing. These are different project objectives and should be specified separately.

An agglomerator increases the bulk density of film or fibrous scrap and produces intermediate material for handling or extrusion feeding. It does not by itself provide the extrusion, melt filtration and controlled cutting used to make finished recycled pellets.

No single configuration should be assumed suitable for every EVA foam. Formulation, crosslinking, fillers and contamination affect the recovery route. Evaluate representative samples and intended reuse before confirming the process; conventional crosslinked foam cannot simply be treated as ordinary remeltable thermoplastic feedstock.

Provide the polymer and waste source, photographs or samples, moisture, contamination and bulk density. State the target incoming feed rate, required pellet output and intended use. Include available power, cooling, floor space and existing pretreatment equipment so the scope and acceptance criteria can be defined.
