PET Flakes Screening & Classification
Creative Vibro Screens provides vibro screening solutions for PET flakes screening and classification, helping processors separate PET flakes according to size and control fines or oversized material in suitable applications.
Screening can be an important step in preparing recycled PET flakes for downstream processing. A properly selected vibro screen can help classify the flake stream and provide more controlled material separation according to the requirements of the process.
PET Flakes Screening Applications
PET flakes produced during recycling and processing can contain a range of particle sizes. Screening helps separate this material into defined size fractions and can remove unwanted fines or oversized pieces where required.
Vibro screens can be considered for PET flake applications including:
-
PET flake size classification
-
Separation of fines
-
Removal of oversized flakes
-
Screening of recycled PET flakes
-
Preparation of PET flakes for downstream processing
-
Separation into different size fractions
The appropriate screening arrangement depends on the flake size distribution, feed rate, required separation, moisture content, and other process conditions.
Vibro Screens for PET Flake Size Classification
Classification is an important part of PET flake processing when a more consistent particle-size range is required.
A vibro screen uses vibratory motion to move material across a screening surface. PET flakes that meet the required size can pass through the selected screen opening, while larger particles are retained for further handling or separation.
By selecting an appropriate screening surface and configuration, a vibro screen can be incorporated into a process where PET flakes need to be separated into different size ranges.
The actual classification performance depends on the characteristics of the PET flakes, screen opening, feed conditions, machine configuration, and other process variables.
Screening PET Flakes After Recycling
PET bottles and other PET materials can undergo several stages during recycling before producing a usable flake stream.
Depending on the recycling process, PET flakes may require screening after size reduction or other processing stages to help control the particle-size distribution.
Screening can form part of the overall material preparation process by separating fines, oversized flakes, or other size fractions before the material moves to subsequent processing.
It is important to distinguish screening from other recycling processes. A vibro screen performs size-based screening and classification; it does not replace processes such as washing, drying, colour sorting, or contaminant separation unless separate equipment is provided for those functions.
Separation of PET Flakes by Size
Different downstream processes may require PET flakes within a particular size range.
Vibro screening can help divide the feed material according to the selected screen openings. Depending on the machine arrangement, multiple screening stages can be considered where more than one size fraction needs to be produced.
Potential screening requirements can include:
Benefits of PET Flake Screening
A properly selected vibro screen can provide several practical advantages in PET flake processing.
Selecting a Vibro Screen for PET Flakes
The correct screening machine depends on the actual characteristics of the PET flakes and the required classification.
Important information for selecting a suitable screening configuration can include:
-
PET flake size range
-
Desired particle-size classification
-
Feed rate
-
Percentage of fines
-
Percentage of oversized flakes
-
Moisture content
-
Number of required fractions
-
Required screen opening
-
Material characteristics
-
Available installation space
-
Existing upstream and downstream equipment
-
Cleaning and maintenance requirements
Providing these details allows the screening system to be considered according to the actual process rather than relying on a standard configuration.
PET Flake Screening for Recycling Applications
PET flake screening can form part of a broader recycling and material-preparation process.
After PET material has been processed into flakes, screening can help classify the flakes by size and separate fractions that do not meet the required range.
Creative Vibro Screens can evaluate the screening requirement based on the material, feed conditions, desired separation, and overall process arrangement.
The objective is to provide a screening solution that fits the process rather than make a generic performance claim applicable to every PET recycling application.

Removal of PET Fines
Very small particles and fines can be separated from the main PET flake stream where the process requires their removal.
Removal of Oversized PET Flakes
Larger flakes that do not meet the desired size range can be retained by the screening surface for separate handling.
PET Flake Classification
Where multiple size fractions are required, the screening system can be configured around the desired classification ranges and process requirements.
Controlled Size Classification
Screening provides a controlled method of separating PET flakes according to the selected screen opening.
Better Material Preparation
A controlled PET flake size distribution can help prepare material for subsequent processing stages where particle size is an important consideration.
Improved Flake Consistency
Separating different size fractions can help create a more consistent material stream for suitable downstream applications.
Continuous Screening Potential
Vibro screening equipment can be incorporated into continuous material-handling systems where the process and machine configuration are suitable.
Fines & Oversized Separation
Screening can help remove unwanted fines and oversized flakes where these fractions need to be separated from the main product stream.
