Shandong Weifang PVC Resin Dense Phase Pneumatic Conveying Case

Case Overview

A leading chemical manufacturer in Shandong Weifang required an efficient and clean method to convey PVC resin powder from its warehouse to the production lines. The existing system faced frequent blockages, high energy consumption, and severe dust leakage, which affected both product quality and workplace safety.

Client Challenges

The client's pneumatic conveying system operated at high velocity and dilute phase, causing excessive wear on pipelines and equipment. Dust emissions not only posed health risks to operators but also led to material loss and frequent downtime for maintenance. The high air-to-material ratio resulted in elevated energy costs, while inconsistent conveying pressure caused fluctuations in production throughput.

HeadPowder Solution

HeadPowder designed and installed a dense phase pneumatic conveying system tailored for PVC resin. By using low velocity and high material concentration, the system significantly reduced pipeline abrasion and energy consumption. A fully enclosed conveying line eliminated dust leakage entirely, while an advanced PLC-based control unit ensured stable pressure and consistent material flow. The integration of a pressure vessel and smart valve timing allowed gentle handling of the resin, preserving its particle integrity.
