Compressing pellet machine is used for compressing plastic file, such as PP, PE etc. Putting the film into the machine, after its working, the volume of film will become smaller, so it is easy to reach high output when recycling.
2. Working Principle:
When the waste plastic is supplied into the chamber of such machine, it will be cut into smaller chips due to the crushing function of the rotating knife and fixed knife. During the crushing processing, the material that soaked up lots heat from the frictional movement of material being crushing and the wall of container will be going to become semi-plasticizing state. The particles will stick with each other due to the function of plasticization. Before it sticks each other completely, the cold water pre-prepared is sprayed into the material being crushed. The water will be evaporated off quickly and the surface temperature of material being crushed drop down quickly also. So the material being crushed will become small particles or granules. It is easy to recognize the particles by different size and can be colored by using of color agent being putted into the container during the crushing processing.
