In global plastic manufacturing, PVC pelletizing lines are vital for producing raw materials for pipes, profiles, cables, and packaging. However, PVCs thermal sensitivity (degrading above 190℃) and impurity-laden raw materials (virgin resin, additives, or recycled scraps) threaten production efficiency and pellet quality. A specialized screen changer is a must-have component for PVC pelletizing lines, solving these pain points through precise filtration, continuous operation, and seamless integr
