Soft Plastic Granulation Line
Customers are granted the freedom to select from two-stage, three-stage, and four-stage machinery, tailored to their unique production needs. With an ingenious design, this system promises seamless compatibility and superior granulation, making it particularly adept at recycling contaminated waste and generating scrap material. The gearbox, a marvel of high-torque engineering, ensures low noise and smooth operation. Equipped with a specialized screw design, it enhances coordination, reducing issues of black spots and color variance in particles. Tailored to the material's properties, it comes with a forced feeding mechanism and hydraulic mesh changer, achieving better capacity while economizing on power. Moreover, the vacuum and conventional exhaust systems efficiently expel moisture, gases, and impurities, resulting in more stable extrusion and top-quality solid particles.
Hard Plastic Granulation Line
This sophisticated Machine Line expertly heats and melts a variety of plastic raw materials, employing a high-speed rotating cutter to transform the molten plastic into small, uniform particles. Throughout the cutting process, the plastic undergoes rapid rotation, stirring, and friction, ensuring the particles' size and shape are uniform, thereby significantly enhancing the plastic's reprocessing performance.
This advanced machine Line effectively minimizes plastic degradation while producing superior quality particles. It's an invaluable asset for clients engaged in recycling PP, PE, and other hard material plastics. Furthermore, its user-friendly operation offers a practical granulation recycling solution, enjoying widespread popularity in the PP and PE recycling domains.

Q: What is the price of a plastic granulation line?
A: Pricing depends on the desired cleanliness of the end material and production capacity needs. We tailor recommendations for the most efficient granulation line within the customer's budget range.
Q: What differentiates single screw, twin-screw, and triple screw granulators? Which suits my requirements best?
A:Single Screw: Simple design, cost-effective, ideal for standard plastics (like single material PP, PE new materials). However, it's less effective with mixed or impurity-laden recycled materials, offering limited capacity.
Twin Screw: Excellent for mixing, suited for recycled, mixed materials (like PP, PE blends), or modified plastics needing additives (such as flame retardants, colorants), providing higher yield and stability.
Triple Screw: Best for high-output and precision tasks (e.g., high-end engineering plastic granulation), though it involves higher costs and complex maintenance.
Suggestion: For recycled or mixed modified materials, a twin-screw granulator is recommended. If dealing with single materials and budget constraints, a single screw granulator remains a viable option.
Q: What is the production capacity per hour or day? Can it be modified?
A: Small Granulator: Produces 50-200 kg/hour, perfect for startups or small-scale operations.
Medium-Sized Granulator: Experience the power of our granulators, boasting a capacity of 200-500 kg/h. These robust machines are commonly utilized in recycling and modified plastic plants, delivering efficiency and reliability that are second to none.
Large Granulator: For those demanding higher outputs, our large granulators exceed 500 kg/hour. They are meticulously engineered to integrate seamlessly with high-power motors and sophisticated automation systems, ensuring optimal performance.
Adjustment Method: Achieve precision in your production process with adjustable capacity settings. Tailor the output by modifying the screw speed, feeding speed, or the mold aperture, allowing for versatile application across various production requirements.
Q: Can your system handle high humidity, impurities, or mixed plastics? Is there a need for material pre-processing like crushing and cleaning?
A: Integration with Pre-Drying: Certain models offer integration with pre-drying systems like hopper dryers. However, raw materials with high moisture content, such as unwashed recycled bottles, will require additional pre-treatment steps like centrifugal dehydration to ensure optimal processing.
Q: Does your extruder support different types of melted plastics? What adjustments are needed when switching raw materials?
A: Melt Index Considerations: The ease of processing materials is influenced by their melt index. For instance, materials like LDPE with a melt index (MI) of 10 exhibit superior flowability compared to HDPE with an MI of 2, facilitating smoother production transitions.
Q: How do you ensure the uniformity, density, and shape of granulated particles?
A: Particle Uniformity: The uniformity of particles is largely dictated by screw design, where a greater aspect ratio promotes more uniform plasticization. Additionally, precise temperature control enhances the consistency of the output.
Particle Shape: The method of cutting plays a pivotal role in determining particle shape:
Underwater Strip Cutting: This technique yields regular particles, ideal for applications with stringent precision requirements.
Hot Cutting Grain: Offers high efficiency, though the output may include some burrs, suitable for less precision-critical applications.
