What structure does the granulator consist of? – Suzhou Polytime Machinery Co., Ltd.

With the development of science and technology and the improvement of people's living standards. On the one hand, the use of plastic has brought great convenience to people's life. On the other hand, due to the extensive use of plastic, waste plastic brings environmental pollution. At the same time, plastic production consumes a lot of non-renewable resources such as oil, which also leads to a shortage of resources. Therefore, unattainable resources and environmental pollution have been widely concerned by all sectors of society, and the plastic granulator for waste plastic recycling has also been paid attention to.

What are the components of plastic?
Plastics are widely used polymer materials, which are composed of polymers (resins) and additives. Plastic composed of different types of polymers with different relative molecular weight have different properties, and the plastic properties of the same polymer are also different due to different additives.

The same kind of plastic products can also be made from different plastic, such as polyethylene film, polypropylene film, polyvinyl chloride film, polyester film, and so on. A kind of plastic can be made into different plastic products, such as polypropylene can be made into a film, automobile bumper and instrument panel, woven bag, binding rope, packing belt, plate, basin, barrel, and so on. And the resin structure, relative molecular weight, and formula used in different products are different, which brings difficulties to the recycling of waste plastic.

What structure does the granulator consist of?
The plastic granulator is composed of the main machine and an auxiliary machine.The main machine is an extruder, which is composed of the extrusion system, transmission system, and heating and cooling system. The extrusion system includes screw, barrel, hopper, head and die, etc. The screw is the most important component of the extruder. It is directly related to the application scope and productivity of the extruder. It makes of high-strength corrosion-resistant alloy steel. The function of the transmission system is to drive the screw and supply the torque and speed required by the screw in the extrusion process. It is usually composed of a motor, reduced, and bearing. The heating and cooling effect of the heating and cooling device is a necessary condition for the plastic extrusion process.
