The working principle of twin-screw extruder:


1. The aspect ratio of the screw of a twin-screw extruder refers to the ratio between the effective length of the screw and the diameter of the screw. Generally, it is between 7 and 18, and the aspect ratio is variable.
2, the steering of the screw of the twin-screw extruder, he is divided into the same direction and anisotropic. The same direction is generally used for compounding, and the anisotropy is generally used for extrusion products.
3. Drive power, in kw, refers to the motor power of the drive screw.
4, the speed range, the low speed of the rod zui to the range allowed by the high speed of zui, the twin-screw extruder can rotate at high speed, and the counter-rotating extruder can only run between 0-40r/min.
5. The nominal diameter of the screw of the twin-screw extruder. This is the outer diameter of the screw. The diameter of the screw is a variable value. The greater the ability to characterize the machining of the machine, the larger the nominal diameter of the screw.
6. The output is the amount of material per hour.
