The second-hand twin-screw plastic extruder production line consists of an extrusion system, a transmission system, and a heating and cooling system. The extrusion system includes a screw, a barrel, a hopper, a machine head, and a mold. The plastic is plasticized into a uniform melt through the extrusion system, and is continuously extruded by the screw head under the pressure established during this process.
Used conical twin-screw extruder for plastic processing industry. The effective length of a press is usually divided into three parts. The effective length of the three segments is determined based on the screw diameter, pitch, and screw depth, usually divided by one-third of each segment. The high-efficiency single screw extruder adopts a two-stage integrated design, enhancing plasticizing function to ensure high-speed, high-performance, and stable extrusion. The special barrier comprehensive mixing design ensures the mixing effect of materials, high shear, low melting point, and plasticizing temperature to ensure high-performance, low-temperature and low-pressure metering extrusion materials.
Advantages of second-hand twin-screw extruder: 
1. Wear and tear condition
Due to its easy opening, the wear level of threaded components and the inner lining of the barrel can be detected at any time, allowing for effective maintenance or replacement.
2. Reduce costs and shorten cycles
Compared to new machinery, second-hand plastic machinery is relatively more affordable, which can reduce the investment cost of enterprises and improve their return on investment. Moreover, due to the higher maturity of second-hand plastic machinery, production efficiency is more stable.
3. Improve labor efficiency
During equipment maintenance, ordinary twin-screw extruders often need to remove the heating and cooling systems first, and then extract the screw as a whole. However, the split twin-screw does not need to be used. Just loosen a few bolts, rotate the worm gear box handle device to lift the upper half of the barrel, and then open the entire barrel for maintenance. This not only shortens maintenance time but also reduces labor intensity.
4. High torque, high speed
At present, the development trend of twin-screw extruders in the world is towards high torque, high speed, and low energy consumption. The effect brought by high speed is high productivity. The split twin-screw extruder belongs to this category, with a speed of up to 500 revolutions per minute. So it has unique advantages in processing high viscosity and heat sensitive materials.
At present, only German and Japanese manufacturers have mastered the core technology of asymmetric and symmetric high torque gearboxes, which can reach speeds of over 1800 revolutions per minute.
5. Wide application range
Widely applicable and suitable for processing various materials.
6. High yield, high quality
Having other advantages of ordinary twin-screw extruders, it can achieve high output, high quality, and high efficiency.
Twin screw extruder is developed on the basis of single screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the forming and processing of extruded products.
