The Principle Of Plastic Granulator

2022-06-14

To make plastic particles, a Plastic Granulator is indispensable, so do you know the principle of this plastic granulator? After the plastic is added to the hopper, the hopper smoothly falls onto the screw and is bitten by the screw thread. With the rotation of the screw, the screw is forced to push it towards the machine head, forming a process of mechanical conveying. When the plastic runs from the feeding port to the machine head, the thread depth of the screw gradually decreases, and also due to the existence of resistances such as the filter screen, the manifold and the machine head, a high pressure is formed during the plasticization process of the plastic, and the material is pressed. It is very dense, which improves its thermal conductivity, helps the plastic to melt quickly, and at the same time gradually increases the pressure to discharge the gas originally existing between the particles from the exhaust hole.

At the same time as the pressure rises, the plastic is heated externally on the one hand, and on the other hand, the plastic itself generates a lot of heat due to internal friction during the movement of compression, shearing and stirring. Under the combined action of external and internal forces, The temperature of the plastic increases gradually, and its physical state also undergoes the change of the glass state - the high elastic state - the viscous flow state.

The above is the principle of plastic granulator. If you want to know more about our company's dynamics or products, you can consult us.
