Phthalic anhydride powder is a fine, crystalline material widely used in the production of plasticizers, resins, and dyes. Its handling requires specialized equipment to prevent dust explosion, product degradation, and environmental contamination. Shandong Headpowder Engineering Co., Ltd. (headpowder) offers a comprehensive pneumatic conveying solution specifically designed for phthalic anhydride powder. This system ensures safe, efficient, and dust-free transfer from storage to processing points. The design takes into account the material's tendency to absorb moisture and its corrosive nature, ensuring long service life and product integrity. All components are engineered to meet the highest safety standards, including explosion-proof ratings and anti-static properties.

Key Products: Phthalic Anhydride Powder Pneumatic Conveying

Our core product line includes the phthalic anhydride powder pneumatic conveying system, which utilizes negative pressure or positive pressure dense-phase conveying technology. The phthalic anhydride powder conveying process is optimized to handle the material's tendency to cake and its sensitivity to moisture. We provide complete phthalic anhydride powder conveying systems that integrate feeding hoppers, rotary valves, blow tanks, pipelines, filters, and control panels. Each component is selected to withstand the corrosive nature of phthalic anhydride and maintain product purity. For customized solutions, please contact our sales manager Mr. Zhang via WeChat: 15662777102. Our team will help you select the right configuration for your specific application, whether it is a single-line transfer or a multi-point distribution network.

System Design and Features

The pneumatic conveying system for phthalic anhydride powder employs a closed-loop design to minimize dust emission and oxygen ingress. Low-velocity dense-phase conveying reduces particle attrition and pipeline wear. Automated controls ensure consistent feed rates and real-time monitoring of pressure, temperature, and flow. The system can be customized for batch or continuous operation, accommodating varying distances and elevations. All contact surfaces are made of stainless steel or special coatings to prevent chemical reaction. Additionally, grounding and explosion-proof components are integrated to comply with safety standards for combustible dust. The control system includes a PLC with HMI interface, allowing operators to adjust parameters and view alarms remotely.

Material Handling Considerations

Phthalic anhydride powder has a bulk density ranging from 0.6 to 0.9 g/cm³ and a particle size of 100-500 microns. It is prone to electrostatic charging and can form explosive mixtures with air. The phthalic anhydride powder conveying system includes anti-static measures such as conductive hoses and bonding straps. Moisture control is critical; therefore, the system uses dry air or nitrogen as the conveying medium. The pipeline layout minimizes bends and vertical drops to prevent blockages. Our engineering team can design a system that handles capacities from 1 ton per hour to 50 tons per hour, with conveying distances up to 200 meters. Inert gas blanketing is available for additional safety when handling the powder in closed vessels.
