Industrial Size Reduction for Plastic Recycling
Plastic recycling begins with size reduction.
Before plastics can be washed, separated or processed into reusable material, they must first be broken down into smaller pieces.
Industrial plastic shredders and granulators are used to reduce large plastic products into flakes or regrind suitable for recycling processes.
Rotajet industrial shredders and granulators are used in recycling plants across the UK, Europe and international plastics recycling markets, helping companies process plastic waste efficiently before washing and separation.
Plastic Materials Processed by Shredders and Granulators
Industrial size reduction equipment must process many types of plastic materials.
Common plastics include:
HDPE
Used for containers, drums and packaging.
LDPE
Used in films and flexible packaging.
PP
Used in automotive components and industrial packaging.
PET
Common in beverage bottles.
ABS
Used in electronics housings and automotive components.
Industrial shredders and granulators must process these plastics efficiently without excessive wear.
Integration with Plastic Washing Systems
After size reduction, plastics are typically processed through washing systems.
These processes may include:
- friction washing
- sink float separation
- rinsing systems
- drying systems
Consistent particle size improves washing efficiency and separation performance.
Rotajet engineers design integrated recycling systems combining shredding, washing and separation technology.
Buy, Rent or Contract Plastic Size Reduction Equipment
Companies installing plastic shredders or granulators have several options depending on their production requirements.
Buy Plastic Shredders and Granulators
Installing a Rotajet plastic shredder or granulator allows recycling plants to control their size reduction process.
Rent Plastic Shredding Equipment
Companies may choose to rent shredding equipment for short-term production increases or trials.
Contract Plastic Size Reduction
Some companies choose to outsource plastic shredding and granulation to contract recycling facilities.
Rotajet equipment is widely used in recycling plants where plastic shredding, washing and separation systems operate together to produce high quality recycled plastics.
Plastic Recycling Trials at Rotajet’s Wakefield Facility
Selecting the correct shredder or granulator often depends on the plastic material being processed.
To support customers in selecting the correct equipment, Rotajet operates a plastic recycling trial facility at our engineering centre in Wakefield, UK.
At this facility we can carry out plastic shredding and granulation trials to evaluate how materials perform during size reduction.
Trials allow customers to evaluate:
- shredding performance
- particle size output
- machine throughput
- blade configuration
- washing compatibility
Materials can also be tested through plastic washing and separation systems.
This allows recycling companies to test materials before investing in full scale recycling equipment.
Companies interested in carrying out trials can contact Rotajet to arrange plastic recycling trials at our Wakefield facility.
