Plastic granulation production line is a process in which waste plastics are processed into granular renewable raw materials through hot processing, melting, adding additives and other processes. The basic principle is to melt the waste plastic under high temperature conditions, and then through filtration, cooling, granulation and other steps, and finally get renewable plastic particles.
▏Main equipment
The main equipment of plastic granulation production line includes:
High mixer: used to mix different kinds of plastic raw materials and additives.
Mixer: Further mixing and plasticizing of plastic raw materials.
Automatic feeding hopper: automatic feeding system to ensure the continuous supply of raw materials.
Granulator: extrudes molten plastic into strips.
Centrifugal cyclone, vibrating distribution screen: used for cooling and separating plastic particles.
Storage bucket: storage of finished plastic particles.
▏Granulation method
There are several common ways of granulation:
Twin-screw granulation: Through the twin-screw extruder, the plastic is transported in a straight line in the barrel to obtain particles.
Air-cooled granulation: the material is extruded from the die hole of the machine head and drawn into a strip, which is cooled by the air-cooled device and then granulated.
Water-cooled granulation: The material is extruded from the die hole of the machine head and pulled into a strip, and then cut into the grain after cooling in the sink.
Spray granulation: After the molten polymer is ejected from the die, it is cut into tiny particles by a high-speed rotating pelleting knife, which is then thrown away and cooled.
Water strip granulation: the material is extruded into strips from the mold mouth, and then cut into particles after cooling through the sink.
▏Production process
The production process of plastic granulation production line generally includes the following links:
Sorting: Sorting and cleaning waste plastics to remove impurities.
Crushing: The waste plastic is broken into small pieces by crushing machinery.
Cleaning: Clean the broken plastic to remove oil and impurities.
Mixing: adding stabilizer, lubricant, modifier and other additives, mixing.
Extrusion granulation: The molten plastic is extruded into strips by the granulator.
Strip cooling: The strip of plastic is cooled by a sink or other cooling device.
Slicing: Cut the cooled strip of plastic into pellets.
Post-treatment packaging: metal impurity removal, classification and grading packaging.
▏Application field
Plastic pelletizing granulation production lines have a wide range of applications, including:
Packaging industry: Used to produce various packaging materials, such as plastic bags, plastic bottles, etc.
Construction industry: Used to produce pipes, doors and Windows and other building materials.
Automotive industry: Used for the production of automotive interior parts, components, etc.
Electronic and electrical industry: used in the production of wire and cable, electrical shell, etc.
▏Maintenance
The maintenance of plastic granulation production line is an important link to ensure its long-term stable operation, mainly including:
Daily maintenance: clean the equipment regularly, check and fill lubricating oil, tighten loose nuts, etc.
Regular inspection: Regular inspection of the main components of the equipment, such as bearings, motors, etc., to ensure their normal operation.
Regular replacement: Regular replacement of severely worn parts, such as bearings, filters, etc.
Shutdown protection: When the equipment is shut down for a long time, anti-rust and anti-pollution measures are carried out.
▏Equipment features
Plastic granulation production line has the following characteristics:
High degree of automation: The equipment adopts advanced control system, high degree of automation, simple and convenient operation.
High production efficiency: The production line can achieve continuous production and high production efficiency.
Stable product quality: Through the precise extrusion and cutting process, the product quality is stable and reliable.
Environmental protection and energy saving: advanced cooling and dust removal devices are used to reduce energy consumption and environmental pollution.
▏Market application
Plastic granulation production line is widely used in the market, with the improvement of environmental awareness and the increasing tension of resources, the recycling of waste plastics has become an important trend. Plastic granulation production line not only promotes the resource utilization of plastic waste, but also promotes the development of circular economy. By recycling waste plastics, it reduces the dependence on and exploitation of native plastics, reduces resource consumption and environmental pollution, and has significant environmental and economic benefits.
