PET Bottle Recycling Washing Line Machines

Waste PET bottle recycling is no doubt the most important part of recycling market. The recycled PET is in good value and has a wide range of application, to be reproduced into: PET strap, PET sheet, PET fiber or even PET bottles.

The quality of waste PET bottles varies greatly, and different customers have different quality requirement of recycled PET. Our company provide customized recycling washing solutions to meet different customer needs.

Description

Quality Table of Final PET Flakes

According to different quality requirement of PET flakes, we have designed two types of PET bottle washing and recycling machine: one type is used to produce PET flakes in normal grade which can be used to reproduce into PET sheet, strap and fibers, etc; the other type is used to produce PET flakes in food grade which are mainly used to reproduce into PET bottles.

Below is the main parameters of PET flakes in normal grade and in food grade.

Normal Grade PET Flakes

Flake size≦16mm or customized
Stacking density0.25-0.35g/cm³
Moisture content<2%
Label content<30ppm
PVC content<250ppm
Glue content<30ppm
Metal content<30ppm
Other impurity content<60ppm
PH value7-8
The above PET flakes parameter is for reference only, and may vary according to the raw material conditions

Food Grade PET Flakes

Flake size≦16mm or customized
Stacking density0.25-0.35g/cm³
Moisture content<2%
Label content<20ppm
PVC content<150ppm
Glue content<20ppm
Metal content<20ppm
Other impurity content<40ppm
PH value7-8

Main Machine Units

Main Machine Units Brief Introduction

As the whole PET bottle washing and recycling line is customized and contains different machine units, we choose main machine units to introduce.

01

Metal Chain Conveyor

This type of conveyor are used to convey baled bottles into the de-baler. It is usually used in recycling machine with output capacity ≧1000kg/h. The bottom of the conveyor sinks into the groud, so forklift can push baled bottles to the conveyor easily. Use metal convey belt to avoid metal strapping rope harm the belt.

02

De-baler

De-baler is used to disperse the PET bottles which are compressed together. It will make PET bottles move freely to next machine.

03

Trommel

Trommel will move PET bottles slowly by rotating of the barrel lined with small holes. During movement of PET bottles, the small impurities on the surface of PET bottles will fall out tough the small holes of the barrel.

04

Label Remover

Label remover is very important part of the whole recycling line. It is used to remove the PVC labels on the surface of the PET bottles. 90-98% of PVC labels will be removed by this machine.

05

Bottle Pre-washing Machine

By injecting high pressure water, this machine can effectively remove debris and sediment from the surface of the bottle. Also some labels on surface of PET bottles can be remove by this machine. It will decrease the working pressure for downstream.

06

Optical Bottle Sorting System (optional)

This sorting system can remove the PET bottles in different color, also it can remove non-PET bottles. It can increase accuracy and efficiency of bottle sorting dramatically.

07

Manual Sorting Belt With Metal Detector And Steel Table

Need workers to work on this machine to manually sort out PVC bottle, labels, and other impurities. Metal detector can alarm and help workers to remove metal to protect the blades of crusher. Steel table is optional.

08

Crusher (with water)

Crusher is used to crush PET bottles into small flakes. By changing outlet sieve mesh size, the output PET flake size will be changed. With water during crushing process to clean the PET flakes. According to different output capacity, we will choose different crusher model and may change number of crushers.

09

Floating Washer

PET flakes will sink to the bottom of the floating washer, then will be washed and conveyed by the screw and the bottom of the washer. The floating material such as PE, PP caps, PVC labels, caustic soda, etc will be removed from the floating washer.

10

Hot Washer

The water inside hot washer will be heated to 90-95℃. Also caustic soda or other detergent will be adde into the hot water. So the oil, glue, dirties will be removed easily by hot washing inside this machine. Also our hot washer has special design for discharging the labels and caps which are floating above the water.

11

High Speed Friction Washer

Through the high pressure water and high speed rotation of paddle inside the machine, PET flakes will be washed well. The chemicals, glue and impurites will be removed though the screen mesh around the paddle.

12

High Speed Dewatering Machine

High rotation speed of rotor inside dewatering water will create strong centrifugal force, most of the water on the PET flake surface will be removed through the screen mesh around the rotor.

13

Label Flake Separator

By suction of the fan at the top of the machine, lable and dust in light weight will be sucked into the collection bag. The heavy PET flakes will fall down to the bottom of the separator and convey to the next machine.

14

Pipeline Metal Detector (optional)

Used to detect the metal inside PET flakes when passing the pipeline. Metal is detected, it will be removed automatically removed by this machine.

15

PET Flakes Sorting Machine (optional)

Used to sort PET flakes in different colors and collect them separately.
