Plastic Recycling and Reclamation Lines

Preparation, reclamation and pelletizing systems for film and PET recycling workflows shown in the catalogue.

Processing challenge

Recycling feedstocks vary in contamination, moisture, bulk density and degradation. Stable feeding, filtration, venting and controlled melt temperature are essential.

Recommended equipment approach

The catalogue shows PET crushing, washing and drying equipment, plus single-screw film reclamation and pelletizing arrangements. System selection depends on feedstock form and contamination level.

Typical materials

Post-industrial or post-consumer film
PET flakes
Thermoplastic regrind
Printed or moisture-bearing feedstock, subject to testing

Pelletizing and downstream

Film reclamation may use strand or die-face pelletizing with filtration and degassing. PET preparation includes crushing, washing, separation and drying before further processing.

Line layouts

Film reclamation, single-screw pelletizing line

Baled or loose film is conveyed to a breaker, fed into a single-screw venting extruder, then cut by a vertical water-ring granulator. Dewatering and sieving follow before the pellets reach the product container. The line covers conveying, breaking, feeding, melting, plasticating, venting, pressure build-up, filtering and pelletizing in one pass, and is applicable to PE, PVC and PET film.

SJ series single-screw extruder pelletizing line for recovered film and regrind — SJ45–180 reclamation line as built, with water bath, blower and cutter.

PET crushing, washing and drying line

For bottle and sheet PET, the line crushes, washes, cooks, friction-cleans and hot-air dries the flake before separation — producing clean, dry flake ready for pelletizing or direct use.

Flow diagram of a PET crushing, washing and drying production line — 1 belt conveyor, 2 crusher, 3 screw conveyor, 4 washing and separating tank, 5 screw conveyor, 6 cooking boiler, 7 twisting cleaner, 8 hot-air conveyor, 9 high-speed washing machine, 10 whirlwind separator.

Machine sizes for recovered material

Model	Screw diameter (mm)	L/D	Driving motor (kW)	Output (kg/h)
SJ-100	φ100	20–32	45–55	100–200
SJ-120	φ120	20–32	55–75	150–250
SJ-150	φ150	20–32	75–90	200–300
SJ-180	φ180	20–32	90–132	250–400
SJ-200	φ200	20–32	160–280	600–800

Output depends on material form (film, flake, regrind), contamination level and moisture. Smaller sizes from SJ45 are available for lower throughputs.
