​Choosing a screw conveyor is not only about selecting a diameter and motor. The right unit must match your material behavior, target throughput, installation angle, and upstream or downstream equipment, while keeping operation stable over long runs.

​PVC pelletizing is different from many other polymers because the process window is narrower and the consequences of poor control show up fast as discoloration, unstable melt, rough pellet surfaces, excessive fines, or even material degradation.

​For small recycling plants, the core challenge is not whether plastic can be pelletized, but whether pelletizing can be done stably, economically, and with predictable quality under limited manpower, space, and capital investment.
