Shandong Headpowder Engineering Co., Ltd. (headpowder) has successfully completed a complex multi‑workshop powder pneumatic conveying project for a titanium dioxide manufacturer located in Ningbo, Zhejiang Province. This project is a typical case of mixed‑phase pneumatic conveying applied to multi‑workshop powder transfer, demonstrating how headpowder’s engineering expertise solves real‑world production challenges in the chemical industry.
The titanium dioxide plant in Ningbo operates several independent workshops, each producing different grades of titanium dioxide powder. The original material handling system relied on manual transport and mechanical conveyors, which led to high labor costs, dust leakage, and frequent cross‑contamination between workshops. The customer urgently needed a reliable, closed‑loop powder conveying solution that could simultaneously serve multiple workshops with different powder characteristics. The core requirement was a mixed‑phase pneumatic conveying system capable of handling both fine and coarse titanium dioxide powders without segregation, while ensuring high transfer efficiency and minimal maintenance.
Designing a multi‑workshop powder conveying system for titanium dioxide presents several unique difficulties. Titanium dioxide is a high‑value, abrasive powder with a tendency to agglomerate under pressure. The conveying distance between workshops exceeded 200 meters, with multiple bends and elevation changes. Moreover, each workshop required different flow rates and batch sizes, demanding a flexible and precisely controlled system. The customer also emphasized the need for a dust‑free environment to comply with strict environmental regulations. After thorough site investigation, headpowder’s engineering team proposed a mixed‑phase pneumatic conveying scheme that combines dense‑phase and dilute‑phase technologies to optimize energy consumption and product quality.
The final solution adopted a centralized positive‑pressure conveying system with multiple discharge points. The system uses a single high‑pressure Roots blower as the air source, connected to a series of rotary airlocks and diverting valves. For the main line from the raw material silo to the workshop distribution station, mixed‑phase pneumatic conveying is employed: the powder is first accelerated in a dilute‑phase section to break up agglomerates, then transferred into a dense‑phase slug flow for long‑distance transport, reducing pipe wear and air consumption. At each workshop inlet, a specially designed cyclone separator and a rotary valve ensure accurate dosing. The entire process is controlled by a PLC system with HMI interfaces, allowing operators to adjust parameters for each workshop independently. This titanium dioxide mixed‑phase conveying approach has proven to be highly effective in maintaining product consistency across multiple production lines.
headpowder supplied all core equipment for this project, including the conveying pipeline made of wear‑resistant stainless steel, heavy‑duty rotary feeders, and a custom‑designed booster arrangement. The system incorporates multi‑workshop powder conveying manifolds with automatic switching valves, enabling seamless changeover between different powder types without disassembly. A special anti‑caking device was installed at the feeding point to prevent titanium dioxide from sticking to the pipe walls. The control software includes a recipe management function that stores the optimal conveying parameters for each grade of titanium dioxide, ensuring repeatable quality. All components were manufactured at headpowder’s facility in Shandong, China, under strict quality control.
The installation was completed within the scheduled 8‑week timeframe, with headpowder’s field engineers providing on‑site supervision and training. During commissioning, the system achieved a conveying capacity of 15 tons per hour with a power consumption of only 0.8 kWh per ton, significantly lower than the customer’s previous mechanical system. The dust emission level was reduced to below 1 mg/m³, meeting the most stringent local standards. More importantly, the mixed‑phase pneumatic conveying system eliminated cross‑contamination between workshops, as the conveying lines are completely purged with compressed air after each batch. The customer reported a 60% reduction in manual labor and a 40% increase in overall production efficiency. This case has become a benchmark for titanium dioxide mixed‑phase conveying projects in the Ningbo region.
