Crush to Create: The Ultimate Eco-Friendly Plastic Shredder Revolution

The working principle of a plastic shredder is mainly to tear large plastic materials into small pieces or fragments through mechanical force, in order to facilitate subsequent processing or recycling. The following is a detailed explanation of the working principle and application of the plastic shredder:

Working principle

1. Feeding system: Firstly, the plastic materials that need to be processed are sent to the crushing chamber of the shredder through manual or automatic conveyor belts.

2. Crushing chamber structure: The crushing chamber is equipped with high-speed rotating double or multiple shafts, which are fitted with sharp blades. These blades may adopt a combination of fixed and movable blades, or a specific shape of tool arrangement, such as a four corner rotating tool, depending on the design.

3. Tearing process: After the motor is started, the blade shaft begins to rotate at high speed. Through the interaction between the blades, the plastic material entering the crushing chamber is torn, squeezed, and sheared, gradually shredding it into smaller pieces. The dual axis design can also produce a certain squeezing effect, which helps to handle materials with higher hardness and reduces the risk of entanglement.

4. Filtration and Separation: Some advanced plastic shredders are also equipped with a filter screen device inside, which can separate liquids such as residual gasoline, water, etc. from the material during the shredding process, achieving effective resource recovery.

5. Discharge control: The crushed plastic fragments are controlled in particle size through a sieve or grid. The fragments that meet the requirements are discharged from the bottom, and those that do not meet the requirements continue to be crushed in the crushing chamber until they reach the set particle size requirements.

Application

1. Plastic recycling: widely used in the pre-treatment of plastic products such as mineral water bottles, PET bottles, plastic buckets, plastic bags, plastic pipes, and waste toys, preparing for subsequent cleaning, melting, and granulation.

2. Resource recycling: The shredded plastic fragments can be further processed into recycled plastic pellets, which can be used to produce new plastic products such as packaging materials, building supplies, household items, etc., achieving the recycling of plastic resources.

3. Environmental treatment: In the waste disposal and environmental protection industry, plastic shredders help reduce the volume of plastic waste, facilitate transportation and storage, and reduce the environmental pressure caused by landfill and incineration.

4. Industrial waste treatment: In addition to daily plastic, it also plays a role in the treatment of industrial waste such as electronic waste, automotive waste parts, medical waste, etc. By shredding and pre-treatment, the reuse rate of waste can be improved.

In summary, plastic shredders are an indispensable part of the plastic recycling industry chain, promoting the recycling and sustainable development of plastic resources through efficient and environmentally friendly methods.
