PET Washing Line

PET washing line is the ideal solution for processing dirty PET bottle bales into “hot washed” PET flakes. Using our standard series of high-tech recycling machinery, the PET flakes produced are not only clean, but contaminant-free making them perfect for use in producing polyester staple fiber or further processing into plastic granules via pelletizing.
Our PET washing line, available with capacities between 500 kg/hr – 3,000 kg/hr, is a highly efficient, fully automatic washing line that is electronically controlled via a central computerized control panel and cabinet.


PET washing equipment before crushing process, removing external impurities as to the fullest extent possible, is very important to gurantee quality of PET bottle and reduce production cost. Take advantage of the special design mechanical structure to create friction among PET bottles inside the machine, and use hot chemical water to separate label, dirt, sand, glue, rubber, metal and other impurities from the bottle. Through detection system, it is able to conduct automatic control over temperature and chemical supplement, to achieve comprehensive automatic control of production process, and guarantee bottle quality to the greatest extent. Supporting chemical water filtration system, using coarse filter, fine filter, precipitation, separate impurities of chemical water in three steps, thus to maintain a longer life of chemical water, saving washing cost.

PET Washing Line Product Feature:
1. High automation, Less man power, low energy consumption, high output
2. Provide whole solution for by-products during production, for example:
variegated bottles, non-PET material, sewage water, labels, caps, metal and etc.
3. With a materials pre-treatment system such as pre-washer, Label processing
module, highly improve quality of end product.
4. Through multiple cold flotation, hot washing and friction washing, fully remove
the impurities, such as glue, organic and inorganic residue.
5. The reasonable process design, reduce maintenance cost and bring convenient
6. Impurity separation effect (customer feedback):
I) Moisture content: 1%.
II) Final PET density: 0.3G / CM3
III) Total impurity content: ≤300 ppm
A-PVC content: ≤300ppm
B-Metal content: ≤100ppm
C-PE / PP content: ≤300 ppm
IV) Final PET size: 14-16 mm

PET washing line first through the crusher will be broken PET bottles into a waste bottle and then through the cleaning equipment into a PET bottle flake clean into a PET bottle debris.
