Jiangsu Taizhou Plastic Powder Negative Pressure Dilute Phase Project

In the industrial sector of Jiangsu Taizhou, a specialized project for handling plastic powder through negative pressure dilute phase conveying was developed to address critical operational challenges. This project focuses on optimizing the transfer of fine plastic powders while minimizing environmental and efficiency issues.

Case Overview

A manufacturing facility in Taizhou was facing difficulties in managing plastic powder during production. The existing material handling method led to frequent blockages, excessive dust emissions, and high maintenance costs. The lack of an efficient conveying system also resulted in inconsistent material flow, affecting overall production line stability.

Customer Pain Points

The customer experienced several persistent issues: (1) Severe dust pollution due to open handling, posing health risks to workers and requiring strict environmental compliance. (2) Frequent clogging in traditional mechanical conveyors, causing unscheduled downtime and reduced throughput. (3) High energy consumption and equipment wear from outdated conveying methods. (4) Difficulty in controlling precise material dosage for downstream processes, leading to product quality variations.

Product Advantages & Solutions

To resolve these pain points, a negative pressure dilute phase pneumatic conveying system was implemented. The system uses a sealed pipeline network with controlled airflow to transport plastic powder from storage to processing points. Key advantages include:

• Complete dust containment: The closed-loop design eliminates dust leakage, ensuring a cleaner work environment and compliance with air quality standards.
• Reliable flow: Dilute phase air velocity is carefully calibrated to prevent powder sedimentation and clogging, even for fine and cohesive materials.
• Energy efficiency: The negative pressure system requires lower power compared to positive pressure alternatives, reducing operational costs.
• Precise control: Integrated sensors and valves allow accurate regulation of material feed rate, enabling stable production and consistent product quality.

The solution also incorporates automatic filter cleaning and pressure monitoring to maintain long-term performance with minimal manual intervention. Since deployment, the facility has reported a major reduction in dust emissions, 30% lower energy usage, and near-zero unplanned downtime related to material transport.
