The wear degree of the cylinder liner and threaded components can be detected in time, effectively repaired or replaced, and unnecessary waste is greatly reduced. The scope of use of twin-screw extruders has become quite extensive, and they are often used to process materials. In addition, in order to meet people's various needs, more and more manufacturers are producing such equipment.

 

First of all, the twin-screw water-cooled strand granulation unit has the principles of a single-screw extruder: solid conveying, melting, pressurization and pumping mixing, steam lifting and devolatilization, but not only that. Research on twin-screw extrusion theory started late. The screw geometry is complex and the extrusion process is complex, which brings many difficulties to the research. On the whole, the research on twin-screw extrusion theory is still in its initial stage, which is what is called "more skill than science".

 Studying its extrusion process can be divided into three links:

1. The physical changes of polymers during the extrusion process, the truth and rules of solid melt transportation and exhaust, and the establishment of mathematical physical models to guide the design of twin-screw water-cooled strand granulation units and the optimization of the extrusion process;

2. Understand the physical changes, mixing forms, structural change processes of two or more polymers and materials during the extrusion process, and the relationship between the final mixture and properties;

3. As a twin-screw water-cooled strand granulation unit, there is an internal relationship between the reaction process, speed, performance and screw structure during extrusion reaction molding. The operating conditions used to guide reaction molding extrusion.

Precautions for using the twin-screw water-cooled granulator:

1. The machine cover/shield is assembled in place and firmly fixed to prevent contact with dangerous parts.

2. Do not enter or stand on the safety cover/shield.

3. It is prohibited to enter the hopper mouth, vent and screw sealing area during cleaning or maintenance.

4. Rotating screws are very dangerous as they can easily get caught in and damage your fingers or anything you put in them.

5. Make sure no one is near the screen changer or operating the screws on the slide bar channel.

6. Wear protective equipment and use handling clamps.

7. Do not open or remove any guards and guards while working.

8. Do not stand near vibrating equipment.
