The gearbox boasts a high-torque design that operates with minimal noise and utmost smoothness. A specially engineered screw design enhances coordination, effectively addressing issues of particle black spots and color discrepancies. Tailored to the material's characteristics, it comes with forced feeding and a hydraulic mesh changer to boost capacity while conserving energy. Furthermore, our advanced vacuum and conventional exhaust systems proficiently eliminate moisture, exhaust gases, and contaminants, ensuring a stable extrusion process and producing premium solid particles.
Hard Plastic Granulation Line
This sophisticated machine line expertly heats and melts various 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 rubbing, resulting in more consistent particle size and shape, thereby enhancing the plastic's reprocessing performance.
The machine line is instrumental in minimizing plastic degradation and producing superior-quality particles, making it an invaluable asset for clients recycling PP, PE, and other hard plastic materials. Moreover, its user-friendly operation and practical granulation recycling mode have garnered significant popularity within the PP and PE recycling industry.

Prospects and Advantages of the Plastic Recycling Industry
1. Environmental Protection
Reducing Pollution: Plastic recycling plays a crucial role in significantly lowering the environmental impact caused by plastic waste, effectively protecting our vital land and water resources.
Resource Conservation: Recycling and reusing plastics help curtail the demand for new, virgin plastics, thus conserving non-renewable resources like oil for future needs.
2. Policy Support
Government Promotion: Governments globally are prioritizing environmental protection, rolling out an array of policies and regulations that foster and support the evolution of the plastic recycling industry.
Economic Incentives: To further stimulate industry growth, some countries offer tax incentives and subsidies to companies involved in plastic recycling.
3. Market Demand
Enterprise Demand: As awareness of environmental responsibility heightens, enterprises increasingly adopt recycled plastics to diminish their ecological impact.
Consumer Preference: The rising demand for eco-friendly products propels consumers to pay a premium for items crafted from recycled materials.
4. Technological Progress
Recycling Technology: Advancements in plastic recycling technology enhance the process, making it more efficient, cost-effective, and yielding products of higher quality.
Innovative Applications: Breakthroughs in materials and processes are unlocking new applications for recycled plastics in various sectors, including construction and textiles.
5. Global Trends
International Cooperation: Global environmental entities and businesses are intensifying collaborations to advance the plastic recycling industry's development.
Standardization: The creation of international standards elevates the quality of recycled plastics, promoting their widespread adoption and circulation in the global marketplace.
The plastic recycling industry is poised for a promising future with numerous benefits: reducing pollution, conserving resources, and benefiting from policy support and market demand. As technology progresses and global cooperation strengthens, the industry stands ready to thrive.
Q: What is the price of a plastic granulation line?
A: Pricing is contingent on the cleanliness of the final material and desired production capacity. We excel at recommending the most efficient granulation line setup tailored to your budget and needs.
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, it's ideal for standard plastics (like single-material PP, PE) but less effective with mixed or impure recycled materials, offering limited capacity.
Twin Screw: Known for robust mixing capabilities, it's perfect for recycled or mixed materials (e.g., PP, PE blends) or modified plastics needing additives, delivering higher output and stability.
Triple Screw: Suited for high-output, high-precision applications (like high-end engineering plastics), though it demands a higher investment and complex maintenance.
Suggestion: When dealing with recycled or modified mixtures, twin-screw granulators are recommended. For single-material processing on a budget, a single screw granulator remains a viable option.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: Offers a flexible output of 50-200 kg/hour, catering to startups or smaller-scale production needs.
Medium-Sized Granulator: Capable of processing between 200 to 500 kg/h, this versatile machine is a staple in both recycling and modified plastic plants, offering efficiency and reliability.
Large Granulator: With a capacity exceeding 500 kg/hour, this powerhouse granulator is designed for heavy-duty operations, requiring integration with high-power motors and advanced automation systems for optimal performance.
Adjustment Method: Seamlessly adjust capacity to meet your needs by modifying screw speed, feeding speed, or the mold aperture, ensuring flexibility and precision in your production process.
Q: Can it handle high humidity, impurities, or mixed plastics? Is there a need for pre-processing such as crushing and cleaning the materials?
A: Indeed, some equipment is compatible with an integrated pre-drying system, like a hopper dryer. However, when dealing with high humidity materials, such as unwashed recycled bottles, additional pre-treatment, including centrifugal dehydration, is necessary.
Q: Is it compatible with various types of melted plastics? Will adjustments be required when switching between different raw materials?
A: Materials with a higher melt index (MI) have enhanced flowability, such as LDPE with an MI of 10, making them easier to process compared to HDPE with an MI of 2.
Q: What are the best ways to control the uniformity, density, and shape of the granulated particles?
A: Achieving particle uniformity hinges on the precise screw design and the accuracy of temperature control, where a larger aspect ratio in screw leads to more consistent plasticization.
The method of cutting dictates particle shape:
Underwater Strip Cutting: Produces regular, consistent particles ideal for applications demanding high precision.
Hot Cutting Grain: Offers high efficiency, though the process may result in particles with burrs.
