Q: What is the price of the plastic granulation line?
A: The price varies based on the cleanliness level of the final material and desired production capacity. We can recommend the most effective granulation line combination tailored to the customer's budget.
Q: What are the differences between single screw, twin-screw, and triple screw granulators? Which one is ideal for my needs?
A:Single Screw: Featuring a simple structure and low cost, it's ideal for ordinary plastics (like single material PP, PE). While it struggles with mixed materials or recycled plastics with impurities, its processing capacity is limited.
Twin Screw: With superior mixing capabilities, it excels in processing recycled or mixed materials, or modified plastics needing additives (like flame retardants, colorants), ensuring higher yield and stability.
Triple Screw: Perfect for high-precision, high-output demands (as in high-end engineering plastic granulation), but comes with higher costs and complex maintenance.
Suggestion: For recycled or mixed modified materials, a twin-screw granulator is recommended. For single raw materials with budget constraints, a single screw granulator is a wise choice.
Q: What is the hourly or daily production range? Is it adjustable?
A: Small Granulator: Offers a production capacity of 50-200 kg/hour, making it suitable for startups or small-scale operations.
Medium-Sized Granulator: Perfectly engineered for operations demanding capacity between 200-500 kg/h, this versatile granulator is predominantly utilized in recycling plants and modified plastic facilities, ensuring efficient and reliable plastic processing.
Large Granulator: Designed for unparalleled performance, our large granulator handles over 500 kg/hour effortlessly. It is fully equipped to work in harmony with high-power motors and state-of-the-art automation systems, delivering top-tier results for large-scale operations.
Adjustment Method: Achieve precise capacity control by fine-tuning screw speed, feeding speed, or mold aperture—each adjustment tailored to meet specific processing needs and enhance operational efficiency.
Q: Is the machine capable of processing plastics with high humidity, impurities, or mixed compositions? What kind of pre-processing, such as crushing or cleaning, is required for these materials?
A: Integrate superior pre-drying solutions like a hopper dryer to manage moisture effectively. However, materials with excessive humidity, such as unwashed recycled bottles, necessitate additional pre-treatment processes, including centrifugal dehydration, to optimize performance.
Q: Does the granulator accommodate various melted plastic types, and are equipment adjustments necessary when switching between different raw materials?
A: Materials with higher melt indexes exhibit greater flowability, enhancing processing ease. For instance, LDPE with a melt index of 10 is more easily processed compared to HDPE with an MI of 2, allowing for a tailored approach to material handling.
Q: What strategies are employed to ensure the uniformity, density, and shape of the granulated particles?
A: The uniformity of particles hinges on the advanced screw design, where a larger aspect ratio promotes consistent plasticization, coupled with precise temperature control for optimal results.
The particle shape is dictated by the cutting method employed:
Underwater Strip Cutting: Delivers regular particles, tailored for applications demanding high precision and consistency.
Hot Cutting Grain: Offers high efficiency, though some burrs may be present, ideal for less stringent requirements.
