2000kg/h Re-make Bottle Level PET Flakes Washing Line
The key to the cleaning and recycling of waste PET bottles is the
removal rate of impurities. The impurities include environmental
pollutants, other materials attached to the original plastic
products, and heterogeneous substances. The higher the purity, the
more high-quality downstream products can be produced, and the
lower the manufacturing cost and production loss of its downstream
products. The Boxin team has a variety of different equipment
combinations to choose from according to the needs of customers. We
combine the composition characteristics of different recycled PET
bottles from all over the world in a modular way, and rationally
match them to meet the requirements of production and investment.
The bottle-to-bottle-level recycling and washing line is mainly
used in the food-grade PET chip recycling project, which has a high
degree of automation and effectively avoids human error.
The drum screening machine ensures the separation of materials from
other debris: removing stones, wood chips, and small metals.
The stripper is mainly used to peel off the label paper on the
surface of the PET bottle, especially the PVC or PS label applied
to the PET bottle. Through the cooperation of the movable knife and
the fixed knife, the label on the bottle body is peeled off
together, and the difference between wind and gravity is used to
separate the bottle body and the label, preserve the integrity of
the bottle and the bottleneck, and reduce the loss of bottle top
The washing line equipped with automatic material sorting machine
and color sorting machine can greatly reduce the investment of
human resources and greatly improve production efficiency, so as to
truly realize a highly automated clean recycling production line.
The sorting system is the sorting and screening of the bottle body
before crushing, screening out a small amount of foreign matter
(including heterogeneous bottles, heterochromatic bottles, a small
amount of label scraps, metal reactants, garbage, etc.) One of the
means of large-capacity production adjustment is crucial to the
stability of process control, and its setting position requires a
deep understanding of the key points of the process. Manual sorting
is a re-inspection and a way to ensure quality.
The crushing system adopts wear-resistant design to ensure the
continuous operation of the system for a long time.
Thermal cleaning effectively removes the remaining viscose, oil and
some small impurities on the surface of the bottle flakes, which is
very important to the life of downstream product filter components
and product quality.
The high-speed centrifugal cleaning system applies corresponding
blade strikes to different materials at a suitable rotation speed
to achieve an ideal cleaning effect.
The drum of the washing tank is designed to be washed under strong
pressure to remove residual impurities.
The corresponding centrifugal dehydration and hot air drying system
can be equipped according to the moisture content set by the
The whole line is automatically controlled, and the units of the
system are associated with each other, and it has a predictive
function for possible abnormal situations.
