LB-PET Bottle Washing& Recycling Line – Langbo

PET bottle recycling is a meaningful and profitable part in the plastic recycling. Most of the drinking bottle is PET. Through crushing the wasted PET bottle, label removing, hot and cold washing, we can get clean and small pieces plastic flakes.

Langbo Machinery has over 12 years experience in the PET washing& recycling lines. We offer the recycling line to industry worldwide, and our recycling program is designed to reduce operating costs and obtain quality PET flakes.

The processing procedure of the complete washing line for PET consists of sorting – label removing–crushing–floating washer with cold water – agitating washer with hot water- floating washer with cold water – centrifugal drying – label separating again–collection.

➢ Belt Conveyor& Crusher
Putting the waste PET bottle on the conveyor, they are transporting the waste into the following process.

➢ Trommel Separator
A large, slow rotating machine utilized to remove small pieces of contamination. At the core of the trommel separator is a large mesh screen tunnel that rotates between 6-10 rotations per minute. The hole of this tunnel are small enough so the PET bottles will not fall down. But the small particles of contamination will fall into the separator.

➢ Label Separator
The stream of plastic leaving the crusher is PET flakes, plastic label and PP/PE rigid plastics from the bottle caps. Figuring out the mixed stream, label separator is essential where a column of pressed air blows away the lighter label and plastic film into a separate collection tank.

➢ Hot Washer
It is a water tank full of hot water, the stream of flakes was washed using the boiling water which sterilized and further gets rid of contaminants such as glues(from the labels being glued on the bottle), grease/oils, and difficult to remove left-overs(beverage/ food).

➢ High-Speed Friction Washer
A secondary friction washer(colder washer) is used to cool and further clean the PET flakes in a scrubbing manner.

➢ Dewatering Dryer
The de-watering machine uses centrifugal or spining force to remove a portion of the flakes. It’s a cost-effective way to get rid of the water covering on the PET flakes. It can save much more energy.
