Q: What is the price of a plastic granulation line?
A: The price is contingent upon the desired cleanliness level of the final material and the production capacity required. We are adept at recommending the most cost-efficient granulation line setup tailored to the customer's budget range.
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: With its straightforward structure and low cost, a single screw granulator is ideal for processing ordinary plastics, such as single material PP and PE. However, it has limitations when handling mixed or recycled materials containing impurities and offers limited processing capacity.
Twin Screw: Known for its robust mixing capability, a twin-screw granulator excels in processing recycled or mixed materials like PP and PE, or modified plastics requiring additives like flame retardants and colorants, providing higher yield and stability.
Triple Screw: Predominantly used in high-output and high-precision scenarios, such as high-end engineering plastic granulation, a triple screw granulator demands a higher investment and involves complex maintenance.
Suggestion: For recycled or mixed modified raw materials, a twin-screw granulator is recommended. If you are working with single raw materials and budget constraints, a single screw granulator is a worthy alternative.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: With a processing capacity ranging from 50-200 kg/hour, this granulator is the perfect choice for startups or small-scale production ventures seeking efficiency and reliability.
Medium-Sized Granulator: Engineered to process 200-500 kg/h, this granulator is a staple in recycling plants and modified plastic facilities, delivering consistent performance and robust output.
Large Granulator: Designed to process above 500 kg/hour, it necessitates integration with a high-power motor and a sophisticated automation system, making it ideal for large-scale operations.
Adjustment Method: Tailor the capacity to your needs by adjusting the screw speed, feeding speed, or mold aperture to optimize efficiency and performance.
Q: Can the machine adeptly handle high humidity, impurities, or mixed plastics? Is there a requirement for pre-processing, such as crushing and cleaning of materials?
A: While certain equipment can integrate a pre-drying system like a hopper dryer, materials with high humidity, such as unwashed recycled bottles, necessitate additional pre-treatment processes like centrifugal dehydration for optimal performance.
Q: Does the equipment offer versatility to support different types of melted plastics? Is equipment adjustment necessary when transitioning between raw materials?
A: The flowability of materials is greater with a higher melt index; for instance, LDPE with an MI=10 is significantly easier to process than HDPE with an MI=2, requiring minimal equipment adjustments.
Q: What are the methods for controlling the uniformity, density, and shape of the produced particles?
A: Achieving uniform particle quality relies on precise screw design, such as a greater aspect ratio for uniform plasticization, coupled with high-accuracy temperature control.
The particle shape is crafted through specific cutting techniques:
Underwater Strip Cutting: Produces regular particles, ideal for applications with high precision requirements;
Hot Cutting Grain: Offers high efficiency but may result in particles with burrs, suitable for less demanding applications.
