Fully Automatic Plastic Bucket & Bottle Rigid Plastic Recycling Washing Equipment – HDPE PP Rigid Material Recycling and Washing Production Line

The HDPE PP rigid material recycling and washing production line is an integrated recycling and processing equipment specially developed for various types of waste rigid plastics. Breaking the process limitations of traditional soft material washing equipment, this rigid plastic recycling line adapts to the full-process processing of rigid plastics, including shredding, deep impurity removal, layered separation and high-efficiency drying. It can complete the refined recycling and purification of multiple rigid plastic materials in one stop, widely applicable to the regenerative processing scenarios of industrial waste rigid plastics.

Unlike flexible film materials such as agricultural films and woven bags, rigid plastics including HDPE milk bottles, plastic buckets, PP pipe materials and head materials feature high hardness, regular structure and stubborn adhered impurities. Ordinary general washing equipment suffers from incomplete shredding, difficult impurity stripping, low material separation accuracy and poor drying effect. The processed plastic flakes retain excessive impurities with uneven dryness, failing to meet high-end recycling processing standards. In contrast, the customized HDPE PP rigid material recycling and washing production line adopts heavy-duty shredding, multi-stage friction washing, precise sink-float separation and closed-loop drying processes. Targetively adapted to the material characteristics of HDPE, PP, ABS, PS and other rigid plastics, it produces final plastic flakes with high cleanliness, uniform dryness and stable qualified quality, which can be directly used for recycled pelletizing, secondary injection molding and profile processing, realizing efficient resource recycling of waste rigid plastics.

Adopting a modular integrated design, the entire HDPE PP rigid material recycling and washing production line features clear division of labor and coordinated linkage for all core accessories. Each equipment unit is optimized and upgraded for the pain points of rigid plastic processing, balancing processing efficiency and finished product quality with definite functions and core values of each component.

1. Variable Frequency Speed-Regulating Feeding Conveyor Belt

Equipped with an upgraded wear-resistant frame and high-strength belt, the conveyor belt adopts a variable frequency speed regulation system, which can automatically adjust the feeding speed according to the load of the rear shredding equipment to avoid machine blockage and overload faults caused by excessive feeding. An optional metal detection device can accurately identify mixed metal impurities in materials, intercepting and protecting the rear heavy-duty shredder in advance, greatly reducing equipment failure rates. It realizes stable, uniform and safe automatic feeding while saving manual sorting costs.

2. Heavy-Duty Single-Shaft Shredder (Supporting Rigid Material Recycling and Washing Production Line)

As the core crushing equipment of the production line, it optimizes the cutting cavity for the high-hardness characteristics of rigid plastics with sufficient internal space and a powerful hydraulic pushing structure. It can easily shred regular rigid materials such as complete plastic buckets, intact plastic bottles, long strip pipe materials and massive head materials. Made of high-strength wear-resistant materials, the tool features impact resistance and durability, producing uniformly shredded particles without bulk residues. It provides standard materials for subsequent deep washing and impurity separation, solving the common problems of ordinary crushers including insufficient crushing, uneven particle size and frequent jamming.

3. Pre-Washing Drum Screen

As exclusive preprocessing equipment for rigid materials, it rapidly strips sediment, dust, oil stains and floating impurities attached to rigid plastic surfaces through rotary spraying and scouring. Meanwhile, it screens out fine stone and debris impurities, reducing the pressure of subsequent washing processes in advance, avoiding accumulation and residue of stubborn impurities, and significantly improving the overall washing and purification efficiency.

4. High-Speed Friction Washer

The core equipment for refined impurity removal of rigid materials drives materials to produce strong friction through high-speed blades. It effectively strips aging surface layers, stubborn oil stains, residual adhesive labels, embedded dust and other impurities that cannot be removed by ordinary water washing, completely solving the industry pain point of firmly adhered impurities on rigid plastics that are difficult to clean, and comprehensively improving the cleanliness of plastic flakes.

5. Sink-Float Separation Washing Tank

A key device for classified recycling of multi-material rigid plastics, it realizes precise sorting by utilizing the density difference of different plastic materials. It can accurately distinguish light plastics such as HDPE and PP from heavy plastics such as ABS and PS, while separating residual sinking impurities and floating residues. It achieves dual effects of material classification and impurity removal, ensuring pure and unmixed recycled materials that meet the processing standards of high-end recycled raw materials.

6. Centrifugal Dewatering + Hot Air Drying Unit

Adopting a dual drying process combination, it first removes most surface moisture of materials through high-speed centrifugal dewatering, and then conducts deep dehumidification via closed-loop hot air circulating drying. It thoroughly solves the problem of water accumulation in gaps of rigid plastic fragments, delivering finished plastic flakes with uniform and stable dryness without moisture residue. The products can be directly stored in warehouses or sent to pelletizing processes, eliminating mildew, caking and subsequent production defects caused by damp materials.

7. Intelligent Electric Control System

It realizes centralized control of the entire production line with one-click start-stop and intelligent linkage, automatically matching the operation rhythm of each process. Equipped with overload protection, blockage early warning and fault self-inspection functions, it features simple operation and convenient maintenance. No professional technicians are required for on-duty operation, greatly lowering manual operation thresholds and production risks.

Standard Working Process

Waste rigid plastics are automatically and uniformly fed via the conveyor belt, with metal impurities intercepted by the metal detector → Bulk rigid materials are shredded into uniform fragments by the heavy-duty shredder → The pre-washing drum screen completes preliminary impurity removal and dust scouring → Materials enter the high-speed friction washer for deep removal of stubborn oil stains and label residues → The sink-float separation tank completes material classification and secondary impurity separation based on density differences → Clean materials undergo dual dehumidification via centrifugal dewatering and hot air drying → High-purity, clean and dry plastic flakes are produced, completing the full recycling process.

Application Fields
