Expert Summary of Details on Double Screw Extruder Equipment

The auxiliary equipment used for different purposes in double screw extrusion units also varies, such as cutters, dryers, and printers. The auxiliary equipment of the double screw extruder mainly includes pay-off devices, cooling devices, meters, preheating devices, traction devices, spark testers, straightening devices, and take-up devices. What about the development of double screw extruders? We interviewed the experts of double screw extruders, and below is our summary of it. Let's take a look.

Analysis of double screw Extruder Equipment

  • The system is equipped with several kinds of cutting pellet methods such as drawing water-cooled cutting, hot cutting air cooling, and hot cutting water cooling, which can be configured according to different materials and user requirements.

  • The main double screw is a high-speed same-direction meshing type, which can produce a very strong and complex material transfer, exchange, diversion, mixing, shearing and kneading effects in various threads and mixing elements. These effects can be fully and easily adjusted and controlled by changing the screw structure and operational process conditions to adapt to the requirements of various processes.

  • Advanced control system. This extruder is equipped with an advanced and beautiful control system, most of which uses imported components of good quality and high sensitivity. The operation parameters of the main unit, such as current, voltage, temperature, torque, are very intuitive, making it very easy to operate, with not too many technical requirements for operators.

  • Accurate measurement and reasonable feeding method are the keys to strictly implementing the formula and ensuring product quality. As a professional double screw extruder supplier, we have equipped with various feeding methods, such as volumetric measurement, dynamic loss measurement, according to the properties of materials and user needs, to meet the needs of different products.

Advantages of double screw extruder

  • Widely used, suitable for processing a variety of materials.

  • High output and high quality, with other advantages of ordinary double screw extruders, can achieve high output and high quality.

  • Intuitive understanding of the wear and tear of vulnerable parts due to its easy opening. Therefore, the wear level of screw components and the lining sleeve inside the barrel can be discovered and effective maintenance or replacement can be carried out in time. This can prevent waste caused by problems occurring during the extrusion of products.

  • High torque and high speed. The development trend of double screw extruders in the world is towards high torque, high speed, and low energy consumption, and the effect of high speed is high productivity. Therefore, it has advantages in processing high viscosity and heat-sensitive materials.

  • Improve labor efficiency. When maintenance is required, ordinary double screw extruders often need to dismantle the heating and cooling systems before removing the screws as a whole. However, the segmented double screw does not require that, raising the upper part of the barrel by rotating the worm gearbox handle  after loosening a few bolts, then opening the entire barrel to complete the maintenance. This not only shortens the maintenance time but also reduces labor intensity.

  • Reduce production costs. When producing pellets, it is often necessary to change the color. If it is necessary to change the product, the open processing area can be opened in a few minutes, and the mixing process can also be analyzed by observing the melt profile on the entire screw. Currently, when ordinary double screw extruders change color, a large amount of cleaning material is needed, which is time-consuming, power-consuming, and material waste.

With more than 20 years of industry experience and installation practice of more than 8000 production lines, Nanjing KY Chemical Machinery Co., Ltd. provides global customers with optimal cost performance and reliable compounding extrusion systems. Our twin screw extrusion machine models range from laboratory test samples by using twin screw extruder lab scale to polyolefin granulation engineering for petrochemical enterprises to meet the latest needs of various related industries.
