Five common problems and countermeasures in plastic granulation processing
The quality of the raw materials themselves is poor, with more black spots;
Local overheating or excessive shearing of the screw can cause material carbonization to worsen;
The head pressure is too high, there is too much reflux material, and the carbonization of the material is aggravated;
The service life of the machine is relatively long, the gap between the screw and the barrel increases, and the adhesion of carbonized substances on the barrel wall increases;
If the natural exhaust port and vacuum exhaust port are not cleaned for a long time, the accumulation of carbonized substances will increase;
Other impurities mixed in due to external environment or human factors;
The mouth mold is not cleaned thoroughly;
The discharge port is not smooth enough, and materials may accumulate over time and be gradually carbonized;
Part of the threaded components were damaged, resulting in increased carbonization of materials at dead corners
