Overview of Solution
An Ethiopian customer has purchased a pp/pe washing crushing pelletizing line from our company.The pp/pe washing line has a capacity of 500 kg/h,while the pp pe granules machine produces 300 kg/h.Both production lines have now been installed at the customer's plastic recycling plant and have completed trial operations,with all equipment running efficiently.The customer requires high-quality,clean,dry,and consistent PP/PE pellets for recycling,necessitating the deployment of a complete PP/PE washing and pelletizing system within their plastic recycling plant.
Features of PP PE Film Woven Bag Washer
Sink-Float Separation Tank:In a plastic pp pe recycling line,the sink-float separation tank is a core component that separates plastics by density.Polypropylene (PP) and Polyethylene (PE) float on water,while heavier contaminants sink.This continuous-feed machine guarantees 98–99% material purity before pelletizing or extruding.
High-Speed Friction Washer:The high-speed friction washer is a critical mechanical cleaning stage in a pp pe washing line. Operating at 1000–1400 RPM,it forces plastic flakes or films to scrub intensely against each other and a surrounding mesh screen,stripping away stubborn dirt,label residue,paper fibers,and glue.
Multi-Stage Drying:Multi-stage drying in a pp pe film washing line is a highly specialized,two-step mechanical and thermal process designed to remove surface water and trapped moisture from plastic flakes.By efficiently dropping the final moisture content to under 1-3%,the plastic is perfectly conditioned for downstream extruding or pelletizing.
Corrosion-Resistant Components:Corrosion-resistant components in a pp woven bag recycling line are essential for handling constant water exposure,aggressive chemical cleaners,and abrasive contaminants like sand and dirt.These heavy-duty elements prevent rust,minimize equipment wear,and ensure the long-term,continuous operation of the recycling plant.
Energy and Water Optimization:Energy and water optimization in a woven bag washing line focuses on closed-loop water recycling,mechanical dewatering to reduce thermal drying loads,and smart temperature controls.Together,these features maximize ringer and flake purity while dramatically reducing operational and environmental costs.
Customizable Layouts:Customizable layouts in a pp woven bag production line allow processors to tailor the plant's footprint to their specific workshop dimensions.By utilizing modular equipment,lines can be configured into flexible L,U,I,or Z shapes,optimizing floor space,improving material flow, and reducing installation costs.
Features of PP PE Plastic Recycling Granulator Machine
Material Versatility:Material versatility in a pp pe plastic recycling granulator machine refers to the system’s ability to seamlessly adapt to diverse polymer types,shapes,and melt viscosities.This flexibility ensures high-quality,homogeneous pellets from varied waste streams.
Continuous Non-Stop Operation:Continuous Non-Stop Operation in pp pe plastic pelletizing machines eliminate production downtime during routine maintenance,such as screen changes.This is achieved using automated hydraulic screen changers and self-cleaning mechanisms,which maintain a constant,stable throughput of uniform plastic pellets.
Intelligent Automation:Intelligent automation in a polypropylene polyethylene pelletizer combines PLC systems,smart sensors,and IoT connectivity to optimize the entire recycling process from feeding to granulation.It minimizes human error,decreases labor requirements to just 2–3 operators,and maximizes throughput while reducing energy consumption.
Advanced Degassing & Drying:Advanced degassing and drying in PP PE granules machines are crucial for removing trapped moisture,volatile organic compounds (VOCs),and gases from the melted plastic.This guarantees highly dense,uniform,and bubble-free pellets suitable for demanding,high-value downstream manufacturing.
Durable Extruder Design:A durable extruder design for a plastic recycling granulator machine prioritizes wear-resistance and consistent melt stability.Key features include nitrided or bimetallic screws/barrels,dual-zone degassing,robust gearboxes,and automated hydraulic screen changers.These maximize uptime while processing abrasive recycled flakes.
