Hard Plastic Granulation Line
This advanced Machine Line is designed to heat and melt a diverse array of plastic raw materials. Utilizing a high-speed rotating cutter, it then slices the molten plastic into consistently small and uniform particles. During this cutting phase, the plastic undergoes rapid rotation, mixing, and rubbing, resulting in uniformly sized and shaped particles. This meticulous process significantly enhances the reprocessing performance of the plastic.
The Machine Line is engineered to combat plastic degradation, yielding superior quality particles. It serves as an indispensable asset for clients involved in the recycling of PP, PE, and other hard plastic materials. Not only is the machine straightforward to operate, but it also represents an incredibly efficient granulation recycling solution, garnering widespread acclaim within the PP and PE recycling sectors.

Q: What is the price of a plastic granulation line?
A: Pricing varies based on the customer's criteria for the cleanliness of the final material and desired production capacity. We can expertly recommend the most efficient granulation line combination tailored to fit within the customer's budget parameters.
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: This option boasts a simple design and low cost, suitable for standard plastic processing (like single material PP, PE new materials); however, it has limitations in handling mixed or recycled materials with impurities, and its processing capacity is restricted.
Twin Screw: Known for its robust mixing capabilities, it efficiently processes recycled materials, mixed composites (like PP, PE blends), or modified plastics requiring additives (such as flame retardants, colorants), offering higher yield and stability.
Triple Screw: This is ideal for high-output, high-precision scenarios (such as high-end engineering plastic granulation). It commands a higher cost and involves complex maintenance.
Suggestion: For recycled or mixed modified raw materials, a twin-screw granulator is recommended; for single raw materials with budget constraints, a single screw granulator is a viable option.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: With a capacity ranging from 50 to 200 kg/hour, this is an ideal solution for startups or small-scale production operations seeking to make a significant impact without the need for high-capacity machinery.
Medium-Sized Granulator: Featuring a substantial throughput of 200 to 500 kg/h, this robust machine is a staple in recycling and modified plastic plants, delivering consistent and reliable performance.
Large Granulator: Capable of processing over 500 kg/hour, this high-capacity granulator is designed to be paired with powerful motors and advanced automation systems to handle industrial-scale plastic waste processing with ease.
Adjustment Method: Tailor the granulator’s capacity effortlessly by modulating the screw speed, feeding speed, or altering the mold aperture, ensuring maximum efficiency and flexibility in operations.
Q: Can it handle high humidity, impurities, or mixed plastics? Do the materials require pre-processing steps like crushing and cleaning?
A: Our advanced equipment can be integrated with pre-drying systems like hopper dryers. However, raw materials with high humidity, such as unwashed recycled bottles, necessitate additional pre-treatment processes like centrifugal dehydration to ensure optimal performance.
Q: Does the machine support various types of melted plastics, and is adjustment required when switching between different raw materials?
A: The melt index significantly affects material flowability; for instance, LDPE with an MI=10 is more manageable than HDPE with an MI=2, allowing for smoother processing transitions.
Q: What methods are used to control the uniformity, density, and shape of the granulated particles?
A: Achieving particle uniformity is reliant on the screw design, where a larger aspect ratio promotes more uniform plasticization, along with precise temperature control throughout the process.
The particle shape is dictated by the cutting method:
Underwater Strip Cutting: Produces highly regular particles, perfect for applications demanding high precision.
Hot Cutting Grain: Offers high efficiency, though particles may come with burrs, suitable for less demanding precision requirements.
