An extruder is a machine that transforms raw materials into plastics. A recycled plastic extruder is a specialized type of extruder that processes plastic waste to produce useful items. Such items can be made directly from the recycled plastic or after compounding and blending it with other materials. In recent years, recycled plastic extruders have played a crucial role in minimizing plastic waste.
Extruders come in two main categories: single-screw and double-screw. Each of them can further process into gears, motors, barrels, screws, pumps, dies, manifolds, and other parts to create a complete recycling system.
Single-Screw Plastic Extruders:
A single-screw recycled plastic extruder comprises a screw, barrel, drive unit, and other auxiliary tools. The main operation of the machine is to convey, melt, mix, and shape plastic materials. Due to the simpleness of the structure, single-screw extruders are more widely used in the plastic industry. In terms of food, it's like whole fruits that are juiced using a single blender.
Co-Rotating Double-Screw Extruders:
A double-screw plastic extruder has two entwined screws turning alongside each other in the barrel. They also mix materials more fully than the single-screw variant, making them ideal for high-demand production lines. Furthermore, the screws can be unwrapped to save energy when melting the plastic. This type of extruder is more complex and is mainly used to create valuable end products from recycled plastic. In a way, it's like complex juicing machinery that extracts every nutrient from different food parts. For many businesses, a double-screw plastic extruder is a worthwhile investment.
Benefits of Recycled Plastic Extruders:
The benefits of plastic recycling extruders are manifold. The machines can save the planet by reducing the growing carbon footprint from the plastic industry. This is because they provide a sustainable means of producing plastic products from waste materials. Secondly, recycled plastic extruders can conserve natural resources by using plastic waste instead of virgin materials. They also lower energy consumption as recycling plastic generally requires less energy than producing new plastic from raw materials. Lastly, the machines can create a circular economy where plastic products are continuously recycled and reused.
Power:
The power of a recycling plastic extruder machine can vary according to the material and output it is meant to handle. Smaller machines suited to low-throughput applications may have a motor with a power rating of around 20-50 horsepower. Mid-sized extruders designed for moderate volumes could have 100-200 horsepower. Larger industrial extruders, particularly those used in continuous recycling lines, tend to have much higher power and could range from 500 horsepower up to several thousand horsepower for very high-capacity models.
Output:
The output of a recycling plastic extruder is typically measured in terms of the amount of plastic processed per unit of time. Output can vary widely depending on the type of extruder, its size, and the plastic material being recycled. A small bench-top or floor-standing extruder might process around 5 to 20 kilograms of plastic per hour. For larger machines, one common benchmark is that a mid-sized extruder can recycle plastic at a rate of 50 to 150 kilograms per hour. More industrial-scale extruders are able to handle much greater throughputs, with some high-capacity models processing between 500 and 1,500 kilograms of plastic every hour. The exact recycling rate depends on factors like the type of plastic being fed in, the motor power, the design of the screw and barrel, and the efficiency of the sorting, shredding, and feeding systems used in combination with the extruder.
Dimensions:
Extruder machines for recycling plastic come in a range of sizes to suit different production needs. The dimensions of smaller desktop models are more compact, while industrial machines take up more floor space. A benchtop extruder may only measure around 2-3 feet in length and 1-2 feet in width. Standalone floor-standing models tend to be closer to 5-7 feet long and 2-4 feet wide. Larger standalone extruders are generally 5-12 feet long and more than 4 feet wide. The height of both small and larger models can be around 5-7 feet. For very large industrial extruders, lengths can be 15 feet or more, while the width may be over 6 feet. The height of these massive machines could exceed 10 feet. Overall, their length, width and height increase considerably to accommodate the bigger capacity and throughput requirements involved in processing plastic waste on an industrial scale.
Like any other machine, a plastic recycling extruder requires regular maintenance to stay in good condition and function properly. Some general maintenance tips are as follows:
