This HDPE PP PS rigid plastic washing plant is used to clean dirty rigid plastics such as HDPE / PP bottles, lumps and or other rigid plastics. This complete recycling solution includes a heavy-duty shredder with overhead magnet, granulator, sink-float separation tank, centrifugal dryer, thermal dryer, zig zag separator and a dual-bag filling station. The resulting high-quality plastic flakes produced can be used in manufacturing plastic products again.
The capacity of this recycling system ranges from 500 kg/hr to 2000 kg/hr.
WORKING PRINCIPLE
Depending on the application the recycling plant may include the following equipment:
- Feeding Conveyor Belt – presents an even material feed to the plant.
- Shredder – shreds the material into smaller pieces for use in granulator.
- Granulator – reduces the size further and makes the plastic stream more uniform.
- Screw Washer – washes and transfers the material into next step.
- Sink-Float Separation Tank – removes contamination and helps wash the material.
- Centrifugal Dryer – dries the product by high speed rotation.
- Thermal Dryer System – dries the material by thermal air.
- Zig-Zag Classifier – removes labels and fine particles.
- Bag Station – delivers the product into storage bags.
- Electrical Panel – provides an interface for the operator to control the system.
We can custom build the whole recycling line as per your requirements.

Frequently Asked Questions
Which materials can this recycling line process?
This line is built for dirty rigid plastics: HDPE and PP bottles, lumps, and other rigid plastic items including PS. The heavy-duty shredder with overhead magnet breaks down bulky items first, then the granulator produces uniform flakes. It is a complete washing and recycling solution for recyclers handling post-consumer or industrial rigid plastic waste streams.
What equipment is included in the line?
Depending on the application, the plant includes a feeding conveyor belt, shredder with overhead magnet, granulator, screw washer, sink-float separation tank, centrifugal dryer, thermal dryer system, zig-zag classifier, dual-bag filling station, and electrical control panel. The full chain — size reduction, washing, separation, drying, and bagging — is integrated into one line we can custom build to your requirements.
What is the line’s capacity?
Capacity ranges from 500 kg/hr to 2000 kg/hr, depending on material type, contamination level, and configuration. Because each plant is custom built per customer requirements, tell our team your material mix and target throughput and we will size the shredder, granulator, washing, and drying stages to match your production goals.
How is this different from a film washing line?
Rigid plastics need different handling than films: bulky items require a heavy-duty shredder and granulator for size reduction, while films need specialized friction washing and dewatering. Our PP/PE film washing line is engineered for films and woven bags; this line is optimized for rigid HDPE, PP, and PS items with features like the sink-float separation tank and zig-zag classifier for label removal.
What can the cleaned flakes be used for?
The resulting high-quality plastic flakes can go back into manufacturing plastic products, or be converted into pellets for higher-value reuse. If you want pellet output, the dried flakes can feed a pelletizing stage — see our plastic pelletizing guide to choose the right line for your material. Clean, dry flakes command better prices and process more reliably downstream.
What maintenance does the line require?
The main wear items are the shredder and granulator blades, which need regular inspection and replacement to hold throughput and flake quality — see our guides on how to change blades on a plastic shredder and how to change blades on a plastic granulator machine. Dryer screens, the overhead magnet, and conveyor parts should also be checked regularly. The electrical panel gives operators centralized control of the whole system.
