Q: What is the price of a plastic granulation line?
A: Prices hinge on the desired cleanliness level of the final material and production capacity. We offer tailored granulation line solutions that align with our clients' budget and operational needs.
Q: What differentiates single screw, twin-screw, and triple screw granulators, and which is optimal for my requirements?
A:Single Screw: With a straightforward design and lower cost, ideal for standard plastics like single-material PP or PE. However, it's less adaptable to mixed or impurity-laden recycled materials, with limited capacity.
Twin Screw: Offers robust mixing, perfect for recycled or mixed materials and modified plastics needing additives, boasting improved stability and output.
Triple Screw: Suited for high-output, precision-intensive applications, like high-end engineering plastic granulation, though it involves higher costs and complex upkeep.
Suggestion: For recycled or mixed-modified raw materials, opt for a twin-screw granulator. For single materials with budget constraints, a single screw option is still viable.
Q: What is the production range per hour or day? Is it adjustable?
A: Small Granulator: With a versatile processing capacity of 50-200 kg/hour, this granulator is perfect for startups or small-scale production environments where efficiency and space are key.
Medium-Sized Granulator: Boasting a robust capacity of 200-500 kg/h, this granulator is a staple in recycling plants and modified plastic facilities, providing reliable and consistent throughput to meet demanding production needs.
Large Granulator: Designed for heavy-duty operations, with a capacity exceeding 500 kg/hour, this powerful granulator requires integration with high-power motors and advanced automation systems to maximize productivity and efficiency.
Adjustment Method: Tailor your production with precision by adjusting the screw speed, feeding speed, or mold aperture to achieve optimal capacity adjustments, customizable to your specific operational requirements.
Q: Can it handle high humidity, impurities, or mixed plastics? Is pre-processing like crushing and cleaning necessary for the materials?
A: While some equipment can feature an integrated pre-drying system, such as a hopper dryer, high-humidity raw materials like unwashed recycled bottles require additional pre-treatment, such as centrifugal dehydration, to ensure optimal processing.
Q: Does it support different types of melted plastics? Is equipment adjustment necessary when switching between raw materials?
A: Materials with a higher melt index exhibit better flowability. For instance, LDPE with an MI of 10 is easier to process than HDPE with an MI of 2, making it essential to consider the melt index for seamless operation.
Q: How can the uniformity, density, and shape of the particles be controlled effectively?
A: Achieving particle uniformity is influenced by the screw design, where a larger aspect ratio can lead to more consistent plasticization. Additionally, precise temperature control plays a crucial role in maintaining uniformity.
The particle shape is influenced by the cutting method employed:
Underwater Strip Cutting: This method yields regular-shaped particles, ideal for applications demanding high precision and quality.
Hot Cutting Grain: Provides high efficiency but may result in particles with burrs, suitable for less precision-critical applications.
