What is the process of crushing plastic?

Plastic crushing is the process of converting large or irregularly shaped plastic waste into small particles or fragments for subsequent recycling, reuse, or disposal. The following is its general process flow:

Preprocessing

• Classification: Firstly, classify the collected plastic waste according to material, color, pollution level, etc. This step is crucial for subsequent crushing and recycling, as different types of plastics may require different processing methods and recycling pathways.
• Cleaning: For plastics with surface impurities such as oil and soil, cleaning treatment is required. Cleaning can remove impurities, improve crushing efficiency and product quality.
• Drying: The cleaned plastic needs to be dried to prevent equipment failure or product quality degradation caused by excessive moisture during the crushing process.

• Feeding: Put the pre treated plastic waste into the feeding port of the plastic crusher. When feeding, attention should be paid to controlling the feeding speed and quantity to avoid blockage or overload.
• Crushing operation: Plastic crushers use tools such as rotating blades, blade wheels, or hammers to cut, shred, or break plastic into small pieces or fragments. During the crushing process, the blades will constantly wear out, so regular inspections and replacements are necessary.
• Screening: The crushed plastic fragments are screened through a sieve to remove oversized or undersized particles and obtain plastic particles that meet the requirements. Screening can be performed multiple times as needed to improve the uniformity and quality of the product.

Subsequent processing

• Collection: Collect the screened plastic particles, usually through a conveyor belt or container. During the collection process, attention should be paid to keeping the equipment clean and dry to avoid impurities from entering.
• Storage: Store the collected plastic pellets for subsequent use or disposal. When storing, choose a dry, ventilated, and dark place to prevent particles from getting damp, discolored, or being damaged in other ways.
• Processing: As needed, the collected plastic particles can be further processed, such as melt granulation, injection molding, etc., to produce new plastic products or raw materials.

Quality Control and Testing

Throughout the entire process, quality control and testing are required for raw materials, intermediate products, and final products. This includes testing the material, color, particle size, impurity content, and other indicators of plastic to ensure that the product meets relevant standards and requirements.

Environmental Protection and Safety

During the plastic crushing process, environmental regulations and safety standards should be strictly followed. Effective measures need to be taken to control pollutants such as noise and dust generated; At the same time, it is necessary to ensure the safe operation of the equipment and prevent accidents and injuries.

In summary, the process of plastic crushing includes multiple stages such as pretreatment, crushing, subsequent processing, quality control and testing, as well as environmental protection and safety. Through scientific and rational process flow and strict quality control measures, plastic waste can be transformed into valuable resources, achieving resource recycling and sustainable development.
