Q: What is the price of a plastic granulation line?
A: Pricing hinges on the purity of the final material and the desired production capacity. We're here to recommend the optimal granulation line configuration that aligns with your budget and ensures the utmost efficiency.
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: Featuring a straightforward design and low cost, ideal for standard plastics like single material PP and PE new materials. However, it struggles with mixed or impurity-laden recycled materials and has limited processing capacity.
Twin screw: Known for robust mixing capabilities, perfect for recycling and processing mixed materials or modified plastics that require additives like flame retardants or colorants. Offers higher yield and stability.
Triple screw: Tailored for high-output and high-precision needs, such as premium engineering plastic granulation. Though offering superior performance, it involves higher costs and complex maintenance.
Suggestion: For recycled or modified mixed raw materials, opt for a twin-screw granulator. If dealing with single raw materials and a limited budget, a single screw granulator serves as a viable option.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: With an impressive capability of processing 50-200 kg/hour, this granulator is perfect for startups and small-scale productions, offering efficiency and reliability.
Medium-Sized Granulator: Handling a robust capacity of 200-500 kg/h, this granulator is a ubiquitous choice in recycling plants and modified plastic plants, renowned for its consistent performance.
Large Granulator: Designed for ambitious operations, this granulator processes over 500 kg/hour. It requires a high-power motor and an advanced automation system to seamlessly integrate into larger scale productions.
Adjustment Method: Achieve optimal capacity by fine-tuning the screw speed, feeding pace, or mold aperture for precise control and enhanced production efficiency.
Q: Can it handle high humidity, impurities, or mixed plastics? Is preprocessing like crushing and cleaning necessary for materials?
A: Some advanced equipment can be paired with a pre-drying system, such as a hopper dryer. However, high humidity raw materials, including unwashed recycled bottles, will still need additional pre-treatment like centrifugal dehydration for optimal results.
Q: Does the equipment adapt to different types of melted plastics? Are adjustments needed when changing raw materials?
A: Materials with a higher melt index exhibit greater flowability, facilitating easier processing. For instance, LDPE with MI=10 processes more smoothly compared to HDPE with MI=2.
Q: How can we ensure the uniformity, density, and shape of the granulated particles?
A: The uniformity of particles is influenced by the screw's design, where a higher aspect ratio promotes consistent plasticization. Precise temperature control is also crucial for maintaining quality.
The shape of the particles is determined by the cutting method:
Underwater Strip Cutting: Produces regular particles that meet high-precision standards, ideal for demanding applications.
Hot Cutting Grain: Offers high efficiency, though there's a possibility of producing particles with burrs.
