Function of PET Granulator Line
A pet plastic recycling granulator machine’s key functions include as follows:
Size Reduction (Grinding):The core function is to reduce waste PET bottles into consistent,small flakes (12mm) using high-speed rotary and stationary knives in a cutting chamber.
Wet Granulation (Washing):Water is sprayed into the cutting chamber during grinding to wash the material and reduce friction. This keeps blades cool,increases their lifespan,and initiates the purification process.
Contaminant Separation:The granulator machine for plastic recycling
includes specialized cleaning stages to separate impurities like labels,caps (HDPE/PP),sand,and metal from the PET flakes based on density using sink-float tanks.
Drying:High-speed vertical or centrifugal dryers are used to remove moisture,resulting in dry,clean,and reusable PET flakes.
Material Valorization:The process converts low-value plastic waste into valuable,high-purity recycled plastic particles (regrind) that can be reused in fiber production,strapping,and new bottles.
This waste plastic granulator machine’s key features include as follows:
High-Performance Cutting (Size Reduction):Features heavy-duty,high-speed rotating knives and stationary counter knives,often using a "V-cut" rotor design for efficient,uniform shredding of bottles into small flakes.
Wet Granulation System:Water is continuously sprayed into the cutting chamber during operation,which acts as a lubricant to reduce friction/heat,minimizes blade wear,and starts the washing process.
Efficient Cleaning & Washing:Our recycling granulator machine typically includes high-speed friction washers and floating tanks to remove contaminants,labels,and residual glue,ensuring high purity.
Advanced Pelletizing & Extrusion:Uses specialized screws (often bimetallic) for optimized melting and self-cleaning.Vacuum degassing systems remove moisture,achieving the low moisture content required for PET.
Automated Operation & Maintenance:Integrated PLC controls allow monitoring of temperature,pressure,and cutting speed.Features like hydraulic screen changers facilitate easy maintenance.
High Throughput & Versatility:Above pet granulator machine is capable of processing 500-6000kg/h,these machines are versatile,handling not just PET bottles but also preforms PET sheet waste.
Advantages of PET Granulator Line
The waste plastic granulator’s key advantages include as follows:
High Efficiency & Throughput: These machines quickly process large volumes of PET bottles,converting them into flakes rapidly,which enhances overall production speed.
Uniform Material Size:Utilizing a screen,the plastic bottle granulator
ensures uniform,precise flake sizes,reducing dust and fines and improving quality for downstream processes (like pelletizing or fiber spinning).
Integrated Cleaning (Wet Granulation):Wet granulators inject water directly into the cutting chamber,allowing for simultaneous grinding and washing to remove label adhesive,glue,and dirt.
Reduced Labor and Handling:This pet bottle granulator can handle bulk feeding,reducing the need for intensive pre-cutting or labor-intensive sorting.
High-Quality Output:By removing contaminants and controlling size,the resulting flakes possess higher purity,making them more valuable for bottle-to-bottle recycling.
Environmental & Economic Benefit:By providing a consistent,clean raw material,these machines allow manufacturers to reduce dependency on virgin plastic,lowering costs and minimizing environmental waste.
Reduced Thermal Degradation:Wet grinding reduces heat generation,protecting the PET material from thermal degradation,which can lower its physical properties.
Durable and Low-Maintenance Components:High-quality hardened steel knives (such as SDK11/D2) are used,which are designed to last longer and reduce maintenance downtime.
Application of PET Granulator Line
Our granulator for plastic recycling’s key applications include as follows:
PET Bottle-to-Bottle Recycling:The primary application is recycling PET water,cola,and beverage bottles back into food-grade PET resin.
Polyester Fiber and Yarn Production:Recycled PET pellets are frequently used to produce synthetic textiles,non-woven fabrics,and fibers for filling (clothing,pillows).
PET Sheet and Packaging Production:rPET pellets are manufactured into packaging sheets (thermoforming),industrial strapping,and food-grade trays.
Compounding and Material Development:These machines are utilized to create specific compounds for industrial use,adding,for example,additives for UV resistance or color.
