Functions and uses of plastic scrap granulator
A plastic scrap granulator is a machine used to process plastic scrap into small granules or pellets. These granules can then be used for various purposes：
1. Recycling: One of the primary functions of a plastic scrap granulator is to recycle plastic waste. It helps in diverting plastic scrap from landfills and reduces the environmental impact of plastic waste.
2. Material recovery: The granulator separates different types of plastic materials, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc., allowing for efficient material recovery. This makes it easier to reuse or sell the processed plastic granules.
3. Manufacturing new products: The granulated plastic can be used as a raw material for manufacturing new plastic products. These granules can be melted and molded into various shapes and forms, such as bottles, containers, pipes, packaging materials, and more.
4. Injection molding: Plastic granules produced by a granulator are often used in injection molding processes. Injection molding involves melting the plastic and injecting it into molds to create complex shapes and components used in various industries like automotive, electronics, and consumer goods.
5. Extrusion: Plastic granules can also be used in extrusion processes, where the granules are melted and forced through a die to create continuous profiles, sheets, or films. Extruded plastic products find applications in construction, packaging, and other industries.
6. Blending: Plastic scrap granules can be blended with virgin plastic granules to create a mix with desired properties. This allows for cost-effective production while maintaining the required quality standards.
7. Energy recovery: In some cases, plastic scrap granulation can be used as a pre-processing step for energy recovery. The granulated plastic can be burned as fuel in waste-to-energy plants, generating heat or electricity.
Plastic scrap granulators play a crucial role in the recycling and reprocessing of plastic waste, enabling the creation of new products and reducing the environmental impact of plastics.
