PET Granulator Machine Application

1. Electronic Scrap Recycling

PET Granulators play a vital role in electronic scrap recycling. The rapid replacement of electronic products generates a vast amount of electronic waste, which contains numerous plastic components, such as computer casings, monitor housings, and printer parts. The HQ-120 single-screw plastic granulator efficiently processes this discarded plastic into high-quality pellets.

2. Home Appliance Plastic Recycling

The home appliance industry is a major consumer of plastics, with refrigerators, washing machines, air conditioners, and other appliances containing numerous plastic components. Once a home appliance is scrapped, these plastic components can be effectively recycled and reused using the HQ-120. For example, polypropylene (PP) and polyethylene (PE) are commonly used plastic materials in home appliances, and the HQ-120 efficiently processes them into pellets that meet quality standards. According to industry data, the performance of plastic pellets recycled in this manner is comparable to that of virgin plastic, but at a 30%-40% lower cost, providing a more cost-effective raw material option for home appliance manufacturers.

3. Automotive Plastic Parts Recycling

The automotive industry is a key area of plastics application, with cars containing numerous plastic parts such as bumpers, dashboards, and interior trim. The HQ-120 single-screw PET Granulator Machine can process a variety of automotive plastic waste, converting it into high-quality pellets for use in the manufacture of new automotive plastic parts or other plastic products. Research shows that using recycled plastic pellets to manufacture auto parts can reduce energy consumption by 70%-80% and lower greenhouse gas emissions, positively impacting the sustainable development of the automotive industry.

4. Packaging Plastic Recycling

The packaging industry consumes a significant amount of plastic materials, such as plastic film, plastic bottles, and plastic boxes. Most of this packaging plastic becomes waste after use, placing significant pressure on the environment. The HQ-120 can be used to process various packaging plastic waste materials, converting them into reusable resources. For example, when processing PET bottles, the HQ-120 can efficiently convert crushed PET bottle flakes into high-quality PET pellets. These pellets can then be reused in the manufacture of new plastic bottles, fiber products, and more.

5. Toy Plastic Recycling

The toy manufacturing industry widely uses various plastic materials, such as ABS, PP, and PE. As toys are replaced and damaged, a large amount of toy plastic waste is generated. The HQ-120 single-screw PET Granulator Machine processes this discarded toy plastic into high-quality pellets for use in manufacturing new toys or other plastic products. According to industry reports, using recycled plastic pellets to manufacture toys can reduce raw material costs by 35%-45%, while also aligning with sustainable development.

PET Granulator Machine Maintenance

1. Regularly Check Screw Wear

Regularly checking the screw wear of your PET Granulator machine is crucial to ensuring long-term, stable operation. It's recommended to shut down the machine and conduct a thorough screw inspection every 500 hours of operation. During inspection, focus on observing the screw surface for scratches, wear marks, and the integrity of the screw threads. Use precision measuring tools to measure the dimensions of each screw part and compare them to the original design dimensions. If screw wear exceeds 0.3mm, repair or replace it promptly.

2. Cleaning and Maintaining the Pelletizing System

The cleaning and maintenance of the pelletizing system directly impacts the quality and production efficiency of plastic pellets. The pelletizing system should be cleaned immediately after each production run. First, turn off the pelletizer power. After the blades have completely stopped rotating, open the pelletizing chamber and remove any remaining plastic pellets and debris. Use a dedicated cleaning tool, such as a copper or nylon brush, to gently scrub the blades and the interior of the pelletizing chamber to avoid scratching the blade surface. Then, inspect the blades for wear and replace them if necessary.

3. Monitor the Temperature Control System

The temperature control system is a key factor in ensuring the quality of plastic pelletizing. Operators should regularly monitor the equipment's eight-zone temperature control system to ensure that the temperature in each zone remains stable within the set range. It is recommended that the actual temperature of each zone be recorded daily before startup and every two hours during operation, and compared to the set temperature. If a zone's temperature deviation exceeds ±2°C, the heater, cooling fan, and temperature sensor should be checked promptly.

4. Maintain the Gearbox and Drive System

The proper operation of the gearbox and drive system is crucial to the equipment's power transmission and overall performance. A comprehensive inspection and maintenance of the gearbox is recommended every 300 hours of operation. First, check the gearbox oil level and quality to ensure that the oil is clean and within the required level. If impurities or water are found in the oil, replace the gear oil immediately. Next, inspect the gear meshing for signs of wear, cracks, or tooth spalling. Also, check the tension and wear of drive system components such as belts and chains, and adjust or replace them if necessary.

5. Clean and Inspect the Feed System

Cleaning and inspecting the feed system is crucial for ensuring a stable supply and accurate metering of plastic raw materials. It's recommended to clean and inspect the feed system weekly. First, turn off the feeder power, open the feed inlet, and remove any remaining plastic pellets and impurities from the feed inlet and feed channel. Use compressed air to blow out dust and debris from the feed system. Next, check the feeder's variable frequency speed controller for proper operation and the feed screw for signs of wear or deformation. If the feed screw is severely worn, replace it promptly.

6. Regularly Maintain the Cooling System

Regular maintenance of the cooling system is crucial to ensure quality cooling of plastic pellets and proper operation of the equipment. A comprehensive monthly maintenance of the cooling system is recommended. First, check the operation of the cooling fans to ensure that each fan is rotating properly and without abnormal noise. Clean any dust and dirt from the fan blades to improve heat dissipation efficiency. Next, check the water in the cooling water tank to ensure it is clean and free of impurities. If significant sediment is detected, clean the tank and replace the cooling water promptly. At the same time, check the working condition of the water suction motor and perform maintenance or replacement if necessary.
