Rigid Plastics Shredder Recycle Machine


Shredding and recycling rigid plastics

Rigid plastics are a type of plastic material that are produced through various thermoforming processes. These plastics are often used in private households and the industrial sector for products such as buckets, watering cans, plastic pallets, trash containers, and pipes.

Unfortunately, many rigid plastics are often mistakenly thrown away in the residual waste garbage can or bulky waste. When this happens, these plastics can no longer be recycled and are often incinerated to generate energy.

To combat this issue, it is important to recycle post-consumer and industrial rigid plastics. One effective way to do this is through shredding with machines like the Rumtoo shredder. By shredding rigid plastics into high-quality recyclate, we can create the foundation for all products made from recycled plastics, thereby promoting sustainable processing practices.

Overall, recycling rigid plastics is crucial for reducing waste and conserving natural resources. By properly recycling these materials, we can extend their lifecycle and create a more sustainable future for generations to come.

What are rigid plastics?

Rigid plastics are a type of plastic material that is stiff, strong, and retains its shape even when not in use. They are produced through various thermoforming processes and include products such as buckets, watering cans, flower pots, pasta strainers, garden furniture, laundry baskets, plastic pallets, trash containers, and pipes. Due to their durability and strength, these plastics are often used in private households and the industrial sector.

Rigid plastics differ from flexible plastics, which are soft and pliable, and are often used for products like plastic bags, packaging films, and shrink wraps. While both types of plastics can be recycled, rigid plastics are often more difficult to recycle due to their size and shape. However, with the use of advanced recycling technologies and machinery, recycling of rigid plastics is becoming more efficient and effective, and is an important step towards reducing waste and promoting sustainable processing practices.

What materials are rigid plastics made of?

Rigid plastics are made of various materials including:

  • PE (Polyethylene)
  • HDPE (High-density Polyethylene)
  • PP (Polypropylene)
  • PS (Polystyrene)
  • PET (Polyethylene terephthalate)
  • PA (Polyamide)
  • PC (Polycarbonate)
  • ABS (Acrylonitrile butadiene styrene copolymer)
  • PVC (Polyvinyl chloride)

Rigid plastics can be produced from thermoplastics using various processes. For example, toys and car parts are manufactured by injection molding, bottles and containers are produced by blow molding, and large hollow bodies such as industrial drums or water storage tanks are produced by rotational molding.

Approximately 65% of the rigid plastics fraction consists of polyolefins such as PP, PE, and HDPE.

Single-Shaft Shredder

Introduction to the component composition and working principle of a single-axis shredder

Single-Shaft Shredder is a mechanical equipment mainly used for crushing, processing and recycling of waste materials. Its main components include the following parts:

  1. Shaft: The shaft is the core component of the single shaft shredder, which drives the blades to crush the materials. The shaft is usually made of high-strength steel and can withstand high-load working environments.
  2. Blades: The blades are important parts on the shaft, used to shear, tear, cut and grind materials. The blades are usually made of high-hardness and high-wear-resistant alloy steel to ensure good crushing effect and long service life.
  3. Feed hopper: The feed hopper is an important part of the single shaft shredder, used to feed waste materials into the machine. The size and shape of the feed hopper are usually designed and optimized according to the material characteristics and processing requirements.
  4. Discharge outlet: The discharge outlet is an important part of the single shaft shredder, used to discharge shredded particles from the machine. The design of the discharge outlet is usually based on material characteristics and processing requirements.
  5. Drive system: The drive system is an important part of the single shaft shredder, used to transmit the power of the electric motor to the shaft and blades. The drive system usually consists of a motor, reducer, coupling and other components.

The working principle of the single shaft shredder is that waste materials enter the machine through the feed hopper, are cut into small pieces by the blades, and are continuously pushed forward until they are shredded into small particles and discharged from the discharge outlet. During the entire crushing process, the high-speed rotation of the blades causes various forces such as friction, shearing and tearing of the materials, thereby effectively crushing and processing waste materials.

Single-shaft VS Double-shaft Plastic Shredders

Single-Shaft Shredders and double-shaft shredders are both used for shredding plastic materials. However, single shaft shredders are designed for processing softer and less dense materials, while double shaft shredders are better suited for harder and denser materials. Single shaft shredders are also generally more cost-effective and require less maintenance compared to double shaft shredders. However, double shaft shredders typically offer higher throughput rates and produce more uniform output. Ultimately, the choice between single shaft and double shaft shredders depends on the specific needs of the industry and the materials being processed.
