Common pelletizing problems and solutions of plastic recycling machine
The processing process of the plastic granulator is basically: raw material classification → raw material crushing and cleaning → automatic feeding into the main machine for plasticization → auxiliary machine extrusion → water or air cooling → automatic pelletizing → bagging. The main components of the plastic granulator include: crusher, washing machine, dehydrator, dryer, extruder, pelletizer, etc. Today, Shanghai Duxia Industry and Trade Co., Ltd. will briefly introduce the common problems and solutions in the pelletizing process. 1. Continuous granulation problem of plastic granulator Concatenated particles refer to the situation where a series of particles are connected to each other, that is, in some cases, the particles are connected to each other through the end of the film or in a tangential manner. During the processing, several process problems may cause this phenomenon alone or together. Too hot processing water is one cause of contiguous particles. In this case, the water temperature should be lowered to give enough quenching to the surface of the particles. Too low water flow rate is also a cause of continuous granulation, which will cause the particle cutting chamber to slow down and particle agglomeration. If the holes of the die are
