Q: What is the price of the plastic granulation line?
A: Pricing varies based on the desired cleanliness level of the final material and the required output capacity. We offer personalized recommendations for the most cost-efficient granulation line configuration, tailored to align with your budgetary preferences.
Q: What is the difference between single screw, twin-screw, and triple screw granulators? Which one is more suitable for my needs?
A:Single screw: Boasting a straightforward design and low cost, single screw granulators are ideal for handling ordinary plastics like single-material PP and PE. However, they are less adaptable to mixed or impurity-laden recycled materials and have a limited processing capacity.
Twin screw: Featuring robust mixing capabilities, twin-screw granulators excel in processing recycled or mixed materials (such as PP and PE blends) and modified plastics that necessitate additive integration, offering higher yield and stability.
Triple screw: Predominantly employed in high-output, high-precision settings, triple screw granulators are perfect for high-end engineering plastic granulation. They are, however, cost-intensive and require intricate maintenance.
Suggestion: For recycled or mixed modified materials, twin-screw granulators are recommended. Conversely, if optimizing cost is a priority and materials are single-type, single screw granulators offer a practical solution.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Introducing our Small Granulator, designed to process 50-200 kg per hour. This model is the perfect choice for startups or small-scale production environments where efficiency and quality are key. It's compact yet powerful, ensuring seamless operation.
Explore our Medium Sized Granulator, capable of handling 200-500 kg per hour. This granulator is a staple in recycling plants and businesses focused on modified plastic manufacturing, providing robust and reliable performance for your medium-scale needs.
Our Large Granulator, designed for processing over 500 kg per hour, is built for high-demand operations. It requires integration with a high-power motor and an advanced automation system to deliver unmatched productivity and efficiency.
Adjustment Method: Tailor your production capacity effortlessly by fine-tuning the screw speed, feeding speed, or mold aperture. This flexibility ensures optimal performance and adaptability to varying production requirements.
Q: Is the machine capable of handling materials with high humidity, impurities, or mixed plastics? Are there any pre-processing steps needed, such as crushing or cleaning of materials?
A: While some of our equipment is compatible with integrated pre-drying systems like a hopper dryer, high-humidity raw materials such as unwashed recycled bottles will necessitate additional pre-treatment processes, such as centrifugal dehydration, to ensure optimal performance.
Q: Can the equipment accommodate different types of melted plastics? Are adjustments required when switching between raw materials?
A: The capability of processing varied plastics with different melt indices depends on flowability. For example, LDPE with a melt index of 10 is easier to process compared to HDPE with an MI of 2, providing flexibility in material usage.
Q: What measures are in place to ensure control over particle uniformity, density, and shape during production?
A: Achieving particle uniformity is reliant on the sophisticated screw design, where a larger aspect ratio results in more consistent plasticization. Additionally, precision in temperature control plays a crucial role in maintaining consistency.
The shape of the particles is influenced by the employed cutting method:
Underwater Strip Cutting: This method produces regular particles, ideal for applications demanding high precision.
Hot Cutting Grain: This approach is highly efficient, yet may result in the creation of burrs.
