Shuliy plastic granulator machine is designed to turn suitable waste plastics into reusable plastic pellets. It uses a screw extrusion process to melt plastic materials and extrude them into continuous strands, which are then cooled and cut into granules.
For different recycling requirements, Shuliy offers multiple popular extruder models with capacities of approximately 3–7 tons per day. A complete plastic pelletizing line can also be configured with auxiliary equipment such as a feeding device, cooling tank, and pellet cutting machine.
Whether you are recycling PP woven bags, PE films, or other compatible plastic waste, we can recommend a suitable configuration based on your raw material, target output, and budget.

Common equipment configurations for plastic granulation
The plastic extruder machine is the core equipment responsible for heating, melting, and extruding plastic. Other equipment is selected according to the production requirements.
typical configuration includes the following equipment:
| 장비 | Main Function |
|---|---|
| Feeding device | Feeds plastic materials into the extruder |
| Plastic granule making machine | Heats, melts, and extrudes plastic |
| Cooling tank | Cools and solidifies the extruded plastic strands |
| Pellet cutting machine | Cuts cooled plastic strands into granules |
The feeding device, cooling tank, and pellet cutting machine can be configured according to the customer’s requirements. In most complete production line solutions, these auxiliary machines are included to support continuous pellet production.
In addition to the aforementioned auxiliary equipment, we also offer plastic crushers, plastic washing machines, and more. You can make your selection based on your specific needs.
How does the plastic granulator machine work?
The plastic pelletizing process mainly takes place in the following stages:
- 급료: Suitable waste plastic enters the plastic extruder machine through the feeding device.
- Heating and melting: The material is heated inside the barrel until it becomes molten.
- Screw extrusion: The rotating screw pushes the melted plastic through the die head.
- Strand cooling: The extruded plastic strands enter the cooling tank and solidify.
- Pellet cutting: The cooled strands are fed into the pellet cutting machine and cut into small granules.
What plastic materials can be processed?
Shuliy plastic granulator machines can be configured for different thermoplastic materials, including:
| Material | Common Waste Sources |
|---|---|
| PP | Woven bags, plastic containers, packaging waste |
| PE | Plastic films, bags, and packaging materials |
| HDPE | Plastic bottles, containers, and rigid products |
| LDPE | Flexible films, bags, and packaging |
| PET | Beverage bottles and PET flakes |
| PVC | Pipes, profiles, and other PVC products |
| PS | Disposable containers and packaging materials |
Can one production line process all these plastics?
Not under the same processing conditions. PP, PE, PET, PVC, and PS have different melting points and processing characteristics. Mixing different plastic types can affect pellet quality and production stability.
For this reason, materials should be sorted by type, and the equipment configuration should be selected according to the specific material. If you plan to process several types of plastic, please provide their details so we can assess whether separate configurations are needed.
Hot-selling models and parameters of plastic pelletizing machines
The SL-125, SL-150, and SL-180 are three popular models. Their main differences are screw diameter, motor power, rotational speed, and processing capacity.
| 사양 | SL-125 | SL-150 | SL-180 |
|---|---|---|---|
| Screw Diameter | 125 mm | 150 mm | 180 mm |
| Main Shaft Speed | 50–70 rpm | 40–60 rpm | 40–50 rpm |
| Main Motor Power | 22 + 1.5 kW | 30 + 1.5 kW | 45 kW |
| 용량 | 3 t/day | 5 t/day | 7 t/day |
Plastic granule making machine price and cost factors
The price of a plastic granulator machine depends on more than the extruder model. A complete production line may include different auxiliary machines and configurations, so the total investment varies from one project to another.
The main factors affecting the price include:
| Price Factor | How It Affects the Cost |
|---|---|
| Machine Model | Larger screw diameters and higher-capacity models generally require a larger investment |
| Raw Material | Different plastics may require different extrusion configurations |
| Production Capacity | Higher output requirements affect equipment selection |
| Auxiliary Equipment | Feeding devices, cooling tanks, and pellet cutting machines add to the line configuration |
| Electrical Configuration | Voltage and other electrical requirements may affect customization |
Electricity consumption and labor requirements
Before purchasing a plastic granulator machine or plastic pelletizing line, customers often consider electricity consumption and the number of workers needed for daily operation.
- Electricity consumption: Approximately 500 kWh per ton of processed material for the complete production line. Actual consumption varies with raw material, equipment configuration, and operating conditions.
- Labor requirements: Approximately 3–4 workers are needed to operate the production line.
These figures can help with preliminary production cost calculations. For a more accurate estimate, the actual material, working hours, and local electricity price should also be considered.
FAQ about plastic pellet making machine
How can I make plastic pellets in different colors?
Pigments can be added during the pelletizing process to produce different colors. The formulation depends on the raw material and the desired color. Please contact us for further guidance.
Can one plastic granulator machine process PP, PE, PET, PVC, and PS?
Different plastic materials have different melting points and processing requirements. They cannot simply be mixed and processed under the same conditions.
How many workers are needed?
Approximately 3–4 workers are required to operate the complete production line.
How often should the filter screen be replaced?
The replacement frequency depends on the cleanliness of the raw material. For relatively clean materials, the screen may last approximately one week. Dirtier materials require more frequent replacement.
What materials are used for the screw and die head?
The screw is made of 38CrMnAl steel, and the die head is made of 40Cr steel.
