Q: What is the price of plastic granulation line?
A: Pricing hinges on the cleanliness level of the final material and desired production capacity. We offer tailored recommendations for the most efficient granulation line setup, aligned with the client's budgetary framework.
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: Known for its simplicity and affordability, ideal for standard plastics (e.g., pure PP, PE), though limited in handling mixed or contaminated materials, with constraints in capacity.
Twin screw: Boasts robust mixing capabilities, perfect for recycled or composite materials, or additives-enhanced plastics, offering superior output and consistency.
Triple screw: Tailored for high-demand, precision scenarios (e.g., premium engineering plastic granulation), albeit with higher costs and intricate maintenance needs.
Suggestion: For recycled or composite modified materials, a twin-screw granulator is recommended; for singular materials and tight budgets, a single screw granulator is a wise alternative.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: Designed for startups and small-scale production, this efficient machine offers a processing capacity of 50-200 kg/hour, providing an ideal solution for businesses beginning their journey in plastic recycling.
Medium-Sized Granulator: Perfect for recycling plants and modified plastic facilities, this granulator boasts a processing range of 200-500 kg/h, making it a versatile workhorse for mid-level operations.
Large Granulator: Engineered for high-volume processing, this robust machine can handle over 500 kg/hour. It requires a high-power motor and an advanced automation system for optimal performance.
Adjustment Method: Tailor your production needs by modifying the screw speed, feeding speed, or mold aperture, allowing for precise capacity adjustments.
Q: Can it efficiently manage materials with high humidity, impurities, or mixed plastics? Is pre-processing necessary (such as crushing and cleaning) before granulation?
A: Certain models come equipped with a pre-drying system like a hopper dryer. However, highly humid materials, such as unwashed recycled bottles, demand additional pre-treatment methods, such as centrifugal dehydration, to ensure optimal processing.
Q: Is the machine compatible with various types of melted plastics? Are adjustments needed when changing raw materials?
A: Materials with a higher melt index exhibit greater flowability; for instance, LDPE with an MI of 10 is processed with ease compared to HDPE with an MI of 2, which may require equipment adjustments.
Q: What are the methods to control particle uniformity, density, and shape?
A: The uniformity of particles is influenced by the screw design, with a larger aspect ratio contributing to more consistent plasticization. Additionally, precise temperature control is crucial.
Particle Shape Determination: Choose your cutting method wisely to get the desired particle shape:
Underwater Strip Cutting: Delivers regular particles, ideal for applications requiring high precision and uniformity.
Hot Cutting Grain: Highly efficient, though it may result in particles with slight burrs, suitable for less stringent applications.
