Plastic shredder are machines used to reduce the size of plastic scrap and waste. They are a critical component of plastic recycling facilities. Shredders break down large plastic parts, bottles, containers, and film into small, uniform pieces called "flakes" or "granules." These small plastic pieces can then be more easily processed and remanufactured into new plastic products.
Shredding plastics is an important first step in the recycling process. It enables easier material handling and separation of different plastic types. It also increases the surface area of the plastics for more effective washing, sorting, and melting processes further down the line. Without shredders, plastic recycling would be far less efficient and economical. Their ability to quickly and consistently break down scrap and waste plastics makes them indispensable equipment for plastic recyclers.
Working Rrinciple
Plastic shredders use rotating cutters or hammers to grind, tear, and break down plastic material into small pieces. The plastic waste is fed into the shredder through a hopper or conveyor belt. It then passes through the cutting chamber where it is impacted by high-speed rotating blades, hammers, or knives.
The cutting edges continuously slice the plastic into smaller and smaller pieces. The size of the output flakes or chips depends on the screen or grate size installed on the discharge side. After shredding, the plastic fragments fall through the grating and are usually sent to the next stage of washing or separation.
Shredders can process rigid plastics like bottles, jugs, buckets, crates as well as softer films and plastic bags. The cutting action tears the plastic material apart while friction and impact help tear it into shreds. Some shredders can handle unwashed plastic with dirt, paper labels, and caps. The shredding process effectively cleans the plastic and prepares it for further recycling processes.
Product choice
Blade shredders use rotating blades to tear and rip the plastic into shreds. They are best suited for rigid plastics like bottles, jugs, buckets, drums etc. Blade shredders produce flakes or shreds typically 10-100 mm in size. Popular models include the sinusoidal reciprocating cutter and rotary shear shredder.
Granulators use a grinding action instead of cutting to break down the plastics. They consist of a rotating rotor embedded with blades that pulverize the plastic into fine granules 2-10 mm in size. Granulators work best on softer plastics like film, plastic bags, plastic sheets etc. They produce very consistently sized granules suited for reprocessing into new products.
In summary:
Blade shredders (reciprocating or rotary shear) are good for rigid plastics. Produce 10-100 mm flakes.
Granulators are ideal for soft plastics like films and bags. Output is fine 2-10 mm granules.
The choice depends on the type of scrap plastic feedstock and desired output size for further recycling processes. Both technologies produce reusable plastic chips and granules from waste plastic.
