Structures of plastic pellet making machine
This plastic pellet making machine is mainly composed of a feeding port, screw press, press chamber, heating device, discharge port, mold head, reducer, machine body, base, motor, and other parts.
This plastic extruder is the main plastic recycling machine of the plastic recycling pelletizing line and can handle a variety of materials. But the recycling machines that handle different materials are not exactly the same. Their appearance is similar, but the diameter of the internal screw, the distance between the screw and the barrel wall, and the length of the screw are all different. They all need to be adjusted according to the material. Therefore, one recycling machine cannot handle multiple materials.
How does plastic granulator machine work?
A plastic recycling granulator is used to melt and extrude plastics of various materials. The extruded plastic is cooled and cut into plastic particles. These particles can be used for secondary production to make new plastic products.
- First, turn on the plastic granulator machine.
- Secondly, observe the operation of the granulator, and put it into use after there is no abnormal sound or vibration.
- Before use, it is necessary to preheat the recycling machine so that it can melt the plastic. If the temperature is too high, the melted plastic will turn black; if the temperature is too low, the plastic will not melt.
- Put the crushed material into the feeding port of the plastic granulator machine, and add a forced feeder for plastic film material to prevent the recycling machines from not feeding.
- The material melts in the squeezing chamber and is pushed out continuously along with the squeezing screw. The material from the main engine will enter the auxiliary engine again for secondary melting and extrusion.
- The material from the outlet can be put into the cooling tank for cooling.

Extrusion system of plastic recycling granulater
The screw is the main part of the plastic pellet making machine. The quality of the screw is directly related to the application range and efficiency of the plastic extruder. The screw is made of high-strength corrosion-resistant alloy steel.
A barrel of a plastic pellet making machine refers to a metal cylinder that is made of alloy steel or composite steel pipe lined with alloy steel. This steel has the characteristics of high heat resistance, high compressive strength, Strong wear-resisting, and corrosion resistance.
The barrel is used in conjunction with the screw to achieve pulverization, softening, melting, plasticizing, venting, and compacting of the plastic. It also conveys the rubber to the molding system continuously and uniformly. Generally, the length of the barrel is more than 15 times its diameter. The main function of it is to make the plastic fully heated and fully plasticized.
A cutting device is installed at the bottom of the hopper to adjust and cut the material. The side of the hopper is equipped with a sight hole and a calibration metering device.
The die head of the plastic recycling granulator has three types, including an electric gear die head, hydraulic die head and automatic slag filter. The function of the machine head is to transform the rotating plastic melt into a parallel linear motion so that the plastic melt is introduced into the mold sleeve evenly and smoothly, and the plastic is given the necessary pressure for molding.
A split sleeve is usually placed to ensure that the plastic flow path in the recycling machine head is reasonable and eliminates the dead angle where the plastic accumulates. Besides, a grading ring is usually also provided to eliminate pressure fluctuations during plastic extrusion. Mold calibration and adjustment devices are also installed on the machine head to adjust and correct the concentricity of the core and the mold sleeve.
Transmission system of PP PE granule extruder
The function of the transmission system of the plastic granulator machine is to drive the screw. It also can provide the torque and speed required for the screw during the extrusion process. In general, the drive system consists of a motor, a reducer, and bearings.
Heating device of plastic pellet making machine
Heating is an important condition for plastic granulation processes. Shuliy plastic pelletizer can provide three different heating methods.
Plastic pellet making machine is generally heated by electricity which is divided into resistance heating and induction heating. The heating piece is distributed in the machine body and the parts of the plastic pelletizer machine’s head. The heating device heats the plastic in the cylinder from the outside, and the heated plastic is in a liquid state, which is convenient for processing.
There are mainly three heating methods for plastic recycling machines. They are electromagnetic heating, ceramic heating, and iron heating. Customers can choose different heating devices according to their demands. Also, customers can consult our sales manager about choosing heating methods.
The cooling device is set to ensure that the plastic is in the temperature range required by the process. Specifically, it is to eliminate the excess heat generated by friction when the screw rotates. It can avoid too high temperatures producing some problems, such as plastic decomposition, plastic burning, or plastic molding difficulties.
Why is plastic granulator so popular?
Plastic pollution has always been a worrying issue for people around the world. As a convenient material, plastic brings convenience to the public and brings us a huge safety problem. Waste plastic contains toxic substances. If burned, they will be detrimental to the air. If buried, they will influence the quality of the groundwater.
If the waste plastic is not properly disposed of, it is likely to result in a large-scale disaster. The plastic recycling pellet machine plays an important role in the environmental problem. Professional equipment can reuse some of the plastic waste to reduce the risk of air and water.
Why choose Shuliy plastic pellet making machine?
A good plastic pelletizer is very important for the whole recycling, which influences the quality of the final plastic pellets. Therefore, how to choose a good machine is worth to be considered.
- Reducers, die heads, and motors of Shuliy granulator machines are all the highest equipment currently on the market.
- Our plastic recycling pellet machine can be customized according to customer requirements or raw materials. Such as the diameter of the screw press, the heating method, the die, the material of the screw press, etc.
- Our company has rich production experience in plastic recycling. There are many different plastic materials on the market. There are many plastic granulator manufacturers who do not understand the material, and mistakenly believe that all the internal structure of the machine is the same. So the machine-made seriously affects the output and quality of the final product.
How does the peculiar smell come from when the plastic pelletizer is granulating?
The old customers who bought our plastic recycling pellet machine have reported to us that there is a strange smell after the waste plastic granulator is granulated. Is the machine damaged? Is this smell harmful to the body? What is the main reason? After experiments and research on this problem, our factory has discovered the cause of the peculiar smell of the plastic granulator.
