Types of Plastic Grinders
Two main types of plastic grinding machines serve industrial needs: disc-type (or plate-type) and turbo-type (or millstone-type). Each design tackles the grinding process differently.
Disc-Type Grinders
These machines utilize two grinding discs. The material is ground using the precise gap between the plates, creating uniform particle sizes through a cutting and shearing action. Adjusting the gap between the two discs allows for precise control of the powder’s fineness.
Turbo-Type Grinders
These employ a high-speed rotating blade within a chamber, and rely on impact to pulverize material. The impact and resulting airflow within the machine, along with the collision of plastic against the chamber’s liner, all contribute to the grinding process. Turbo-type models often excel with less rigid materials.
The DLMF Series: Efficient PVC Granule Production
The DLMF series of plastic grinding machines, offered by companies like OUNICE, offers a practical solution for PVC recycling. These machines efficiently process a variety of materials, turning waste into reusable granules. Here’s a closer look at their capabilities based on the provided technical parameters:

Main Power | 2.2 KW | 4 KW | 4 KW |
Rotating Diameter | 500 mm | 600 mm | 800 mm |
Fan Power | 4 KW | 5.5 KW | 11 KW |
Number of Blades | 12+24 | 13+26 | 15+32 |
Vibration Screen Dia. | 800 mm | 1000 mm | 1200 mm |
Production Output | 150-200 kg/h | 200-450 kg/h | 500-800 kg/h |
Weight | 1500 kg | 2000 kg | 2800 kg |
Choosing the Right Model
- DLMF-500: This model is a smart choice for smaller operations or pilot projects. It delivers a production capacity of 150-200 kg/h.
- DLMF-600: Mid-sized facilities with larger production demands find the DLMF-600 suitable. Its capacity ranges from 200-450 kg/h.
- DLMF-800: The most robust option, the DLMF-800, is ideal for large-scale industrial applications. It boasts a production output of 500-800 kg/h.
Key Operational Advantages
- High Output: These machines handle substantial throughput, ensuring efficient processing.
- Adjustable Mesh Size: The mesh size of the output granules is adjustable, providing flexibility for different applications.
- Easy Maintenance: The design of these grinders focuses on convenient maintenance, minimizing downtime.
- Low Energy Consumption: Compared to similar products, these machines consume less energy, promoting cost-effectiveness.
- Environmental Considerations: With closed-loop designs, the DLMF series minimizes dust and contamination.
The Role of Granule Size in Plastic Manufacturing
The size of plastic granules significantly affects their suitability for different manufacturing processes. Here’s a brief overview:
- Fine Powders (e.g., under 30 mesh): Used in rotational molding, coatings, and some extrusion processes where a smooth finish is essential.
- Medium Granules (e.g., 30-80 mesh): Common in injection molding, blow molding, and extrusion, offering a good balance of flowability and mechanical properties.
- Coarse Granules (e.g., over 80 mesh): Suitable for certain extrusion processes and applications where surface finish is less critical.
Conclusion
Automatic PVC granule grinding machines, like the DLMF series, are essential for efficient plastic recycling. Choosing the right model and understanding the principles of operation ensures a productive and profitable process. As the plastics industry moves towards greater sustainability, these machines will play an increasingly vital role in reducing waste and conserving resources.
