Differential Twin Screw Machine--a High-tech Magic Machine

The wheels of the times are always rolling forward. No matter which industry it is, it will be eliminated by the times without development. This is an eternal law. Nanjing KY Chemical Machinery Co., Ltd has been at the forefront of twin-screw extruder technology since its establishment. We have always been committed to providing customers with first-class technology and equipment. Below we will show you the latest magic machine equipped by KEYA.


1. The technology of the differential twin screw machine


This machine uses the asymmetric differential co rotating twin screw extruder technology jointly developed by Nanjing KEYA and the scholar Xu Baiping of Guangdong Industry Technical College, breaking through the traditional co-rotating twin-screw constant speed rotation and two-screw shape The same industry-recognized common sense, creatively uses two screws with completely different shapes to rotate at a differential speed to complete the whole process of polymer material processing.


The two screws have different speeds, but they also maintain the self-cleaning function. The use of the symmetry breaking of the two screws with different configurations makes the material undergo periodic compression during the forward conveying process. The introduction of two key technologies, stretching field action and chaotic mixing, significantly enhances the heat and mass transfer process. In this way, the melting capacity of the material is greatly improved.


2. Advantages of the differential twin screw machine


The differential twin screw extruder changes the dynamics of the material, and induces chaotic mixing in the processing process by introducing symmetry breaking, which effectively strengthens the distributed mixing of the equipment; at the same time, the machine introduces a strong periodic stretching force field. , Fully and effectively improve the dispersion and mixing of the equipment; therefore, compared with the traditional co-rotating twin-screw extruder, the differential twin-screw extruder has a smaller volume and can save energy by more than 30%.


The differential twin-screw extruder will exert its powerful advantages in the fields of high filling, color masterbatch, functional masterbatch, and shear sensitivity. It is expected to replace the continuous internal mixer and undertake more complex mixing tasks. It is a new generation of twin-screw extruder.


"Focus on customer success" has always been the business philosophy of Nanjing KEYA. It is with this philosophy that we not only have a large number of old customers who have witnessed KEYA's growth, but also more new friends who come here admiringly. KEYA's only wish: keep your original intentions unchanged, and accompany you all the way forward.
