Q: What is the price of a plastic granulation line?
A: Pricing is contingent upon the desired cleanliness level of the end material and the required production capacity. We can recommend the most efficient granulation line configuration tailored to the customer's budget.
Q: What are the differences between single screw, twin-screw, and triple screw granulators? Which is best suited for my requirements?
A:Single Screw: Boasting a straightforward design and low cost, this option is ideal for processing standard plastics (like single material PP, PE), yet it has limited adaptability for mixed or impurity-laden recycled materials, with constrained processing capacity.
Twin Screw: With robust mixing capabilities, it excels at processing recycled or mixed materials (such as PP, PE mixes) and modified plastics that incorporate additives (like flame retardants, colorants), offering superior yield and stability.
Triple Screw: Typically deployed in high-output, high-precision scenarios (such as advanced engineering plastic granulation). It commands a higher cost and involves more intricate maintenance.
Suggestion: For recycled or mixed-modified raw materials, a twin-screw granulator is recommended; for single raw materials with budget constraints, the single screw is an excellent alternative.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: Perfectly designed for startups or small-scale production, this efficient machine processes between 50-200 kg/hour, offering ideal support for evolving businesses.
Medium-Sized Granulator: Typically found in dynamic recycling plants or modified plastic facilities, this versatile machine processes an impressive 200-500 kg/h, ensuring seamless operation and robust output.
Large Granulator: Tailored for substantial production demands, this powerhouse unit excels with outputs above 500 kg/hour, necessitating a high-power motor and sophisticated automation system for optimal performance.
Adjustment Method: Maximize your production with capacity adjustments through precise screw speed, feeding speed, or mold aperture changes, ensuring flexibility and efficiency in every operation.
Q: Can it effortlessly manage high humidity, impurities, or mixed plastics? Are there specific pre-processing steps required, such as crushing and cleaning?
A: Some advanced systems include integration with pre-drying tools like a hopper dryer. However, for optimal results with high humidity raw materials—such as unwashed recycled bottles—additional pre-treatment steps like centrifugal dehydration are recommended.
Q: Does the system accommodate various melted plastic types? Is equipment adjustment necessary when transitioning between different raw materials?
A: The melt index is crucial—materials with a higher melt index exhibit superior flowability. For example, LDPE with MI=10 is more processing-friendly compared to HDPE with MI=2.
Q: What methods are in place to control the uniformity, density, and shape of the granulated particles?
A: Particle uniformity is largely influenced by the screw design—where a larger aspect ratio contributes to more uniform plasticization—and precise temperature control is key.
Particle shape is engineered through cutting method selection:
Underwater Strip Cutting: Produces regular particles, ideal for high-precision requirements;
Hot Cutting Grain: Offers high efficiency, with minimal risk of burr formation.
