What is the process flow of the plastic recycling machine? – Suzhou Polytime Machinery Co., Ltd.

With the continuous development of the plastic industry, waste plastics cause potential and serious harm to the environment. The recovery, treatment, and recycling of plastics have become a common concern in human social life. At present, the comprehensive treatment of the recovery and recycling of waste plastics has become the most urgent problem to be solved.

What are the classifications of plastics?
There are many classification methods of plastics. According to different physical and chemical properties, plastics include thermosetting plastics and thermoplastics. According to the application scope of plastics, plastics can be divided into three categories: general plastics, engineering plastics, and special plastics.

1. General plastics

The so-called general-purpose plastics refer to those used for the mass production of industrial products. They have good formability and low price. It accounts for most of the use of plastic raw materials.

2. Engineering plastics

Engineering plastics have good mechanical properties, good dimensional stability, high-temperature resistance, and chemical corrosion resistance. They are mainly used in engineering structures. Such as polyamide, polysulfone, etc. It can be widely used in daily necessities, machinery, and electronics industries.

3. Special plastics

Special plastics refer to plastics with special functions and can be used in special fields. Special plastics such as conductive plastics, magnetic conductive plastics, and fluoroplastics, among which fluoroplastics have very excellent characteristics of self-lubrication and high-temperature resistance.

How are plastic recycling machines classified?
A plastic recycling machine is a general term for a series of plasticizing and recycling machines for waste plastics, such as screening and classification, crushing, cleaning, drying, melting, plasticizing, extrusion, wire drawing, granulation, and so on. It does not only refer to a specific machine but a summary of waste plastic recycling machines, including pretreatment machines and pelletizing recycling machines. Pretreatment equipment is divided into the plastic crusher, plastic cleaning agent, plastic dehydrator, and other equipment. Granulation equipment is also divided into plastic extruders and plastic pelletizer.

What is the process flow of the plastic recycling machine?
A plastic waste recycling machine is a recycling machine suitable for daily life and industrial plastics. The process flow is to first put the waste plastics into the hopper and transport the materials to be crushed from the conveyor belt to the plastic crusher. After that, the materials are preliminarily processed through crushing, water washing, and other treatments, and the crushed materials will then pass through the friction cleaning conveyor for strong friction cleaning. Next, the rinsing tank will rinse the waste plastic fragments to remove impurities, and the material will be transported to the washing tank in the next link for rinsing again. After that, the drying opportunity dehydrates and dries the cleaned materials, and the automatic feeding opportunity will send the materials to be granulated into the main machine of the plastic granulator in an orderly manner. Finally, the plastic granulator can granulate the material, and the cooling tank will cool the plastic strip extruded from the die. The plastic granulator controls the size of the plastic particles by frequency conversion control.

At present, the use of plastics is huge all over the world. The traditional treatment methods of incineration and landfill of waste plastics are not suitable for the current global development situation. Therefore, when we use plastic products to bring convenience to our mankind, we also need to think more about how to recycle the used waste plastics. Since its establishment in 2018, Suzhou Polytime Machinery Co., Ltd. has developed into one of China's large-scale infrastructure production bases and accumulated many years of experience in the plastic industry. If you are engaged in waste plastic recycling or have purchase intention, you can understand and consider our high-quality products.
