Q: What is the price of plastic granulation line?
A: Pricing varies based on the cleanliness of the final material and desired production capacity. We can recommend the most efficient granulation line configuration within the customer's budget.
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: Features a simple structure and low costs, ideal for ordinary plastics (e.g., single material PP, PE new materials). However, it struggles with mixed or impurity-laden recycled materials and has limited processing capacity.
Twin screw: Offers robust mixing capabilities, perfect for recycled materials, mixed materials (e.g., PP, PE blends), and modified plastics needing additives (like flame retardants, colorants), with superior yield and consistency.
Triple screw: Typically used for high-output, high-precision scenarios (such as high-end engineering plastic granulation), albeit with higher costs and complex maintenance.
Suggestion: For recycled or mixed modified materials, a twin-screw granulator is optimal; for single raw materials and tight budgets, a single screw granulator is a prudent choice.
Q: What is the hourly or daily production range? Can it be adjusted?
A: Small Granulator: Efficiently designed to process 50-200 kg per hour, this granulator is ideal for startups or small-scale production. Step into the world of plastic recycling with ease and reliability.
Medium Sized Granulator: Capable of handling 200-500 kg per hour, this granulator is a staple in recycling plants or modified plastic facilities. It offers the perfect blend of performance and versatility.
Large Granulator: Designed for high-demand scenarios, this powerhouse processes over 500 kg per hour. It seamlessly integrates with high-power motors and automated systems for optimized performance.
Adjustment Method: Easily alter capacity by adjusting the screw speed, feeding speed, or mold aperture. Tailor the operation to meet your specific production needs efficiently.
Q: Can the equipment manage high humidity, impurities, or mixed plastics? Are there any material pre-processing requirements such as crushing and cleaning?
A: While some machines can incorporate a pre-drying system like a hopper dryer, materials with high humidity, such as unwashed recycled bottles, necessitate additional pre-treatment, including centrifugal dehydration.
Q: Is it capable of processing various types of melted plastics? Are equipment adjustments necessary when switching raw materials?
A: Materials with a higher melt index exhibit greater flowability. For example, LDPE with an MI of 10 is processed more easily compared to HDPE with an MI of 2.
Q: How can one ensure the uniformity, density, and shape of the granulated particles?
A: Achieving uniform particle size relies on precision screw design, such as an increased aspect ratio for consistent plasticization, coupled with accurate temperature control.
The cutting method dictates particle shape:
Underwater Strip Cutting: This method produces regular particles, ideal for applications requiring high precision.
Hot Cutting Grain: Offers high efficiency, though the particles may feature burrs.
