Plastic Crusher Granulator

The plastic crusher granulator is a high-speed, low-torque machine that plays a key role in plastic recycling by refining plastic waste into smaller, uniform particles between 3 mm and 30 mm. Available in two main designs--an open rotor for lighter materials and a closed rotor for thicker materials--the equipment increases recycling efficiency, promotes environmental sustainability by reducing landfill use and plastic pollution, and provides a cost-effective solution for quickly processing large volumes of plastic waste. The refined pellets have a higher market value and can be used to produce a variety of plastic products, making the plastic crusher granulator an essential tool in recycling centers, manufacturing plants, and waste management facilities.

1. Specifically designed for PE/PP scrap film flake processing: This PE/PP film bag crusher granulator has been carefully designed to efficiently process PE (polyethylene) and PP (polypropylene) scrap film flakes. The design ensures an optimal feeding, crushing, and granulation process, specifically tailored to the physical characteristics of these materials. By focusing on this market segment, the machine maximizes output and minimizes wear, resulting in a longer service life and lower maintenance costs. In tests conducted, the machine has demonstrated a processing capacity of up to 500 kg/h of PE/PP film flakes, far superior to ordinary plastic crusher granulators.
2. Flexible granulation options for a wide range of material processing: The machine has the flexibility to use a single or dual-stage granulation line, depending on the material characteristics and processing requirements. For example, rigid materials may require more aggressive crushing action in the first stage, followed by finer granulation in the second stage, while film flakes may require a smoother single-stage process to maintain fiber length and quality. This modular approach allows for customized configurations, thereby increasing overall productivity and material output. Dual-stage pelletizing improves product uniformity by 20%, reducing the need for secondary processing.
3. Customized screw design for optimal material processing: The screw's length-to-diameter ratio (L/D) is carefully tuned to the material condition, such as whether it is a hard material or thin film flakes. For hard plastics, a longer L/D ratio (typically 25:1 or higher) ensures thorough melting and mixing, resulting in high-quality pellets. Conversely, thin film flakes benefit from a shorter L/D ratio (approximately 15:1 to 20:1) to maintain efficient conveying and reduce shear heating that degrades material quality. This precision engineering reduces energy consumption and improves product quality. A properly optimized screw can reduce energy consumption by up to 15% compared to a standard configuration.
4. Integrated metal detection to ensure product purity: The line is available with optional advanced metal detectors, which play a vital role in ensuring the quality of the end product. These detectors can identify and reject contaminants such as metal fragments or particles with great accuracy, typically achieving a detection sensitivity of 0.5 mm or less. This measure not only protects the integrity of the plastic pellets but also prevents expensive damage downstream to the molding machine and the final product. In industries such as food packaging where product purity is critical, the use of metal detectors can significantly improve customer satisfaction and brand reputation and reduce the risk of product recalls and legal disputes.
