Shandong Headpowder Engineering Co., Ltd. (headpowder) recently completed a critical pneumatic conveying system for a rare earth powder processing facility in Tver, Russia. This project is a landmark case in the field of nitrogen protection pneumatic conveying, specifically tailored for the safe and efficient transfer of highly reactive rare earth powders. The entire system was designed and manufactured at headpowder’s headquarters in Shandong, China, and exported to the Tver region, where it now operates under strict quality control standards.
Rare earth powders, due to their fine particle size and chemical reactivity, require an inert atmosphere to prevent oxidation, dust explosion, or contamination. The Tver project employs a closed-loop nitrogen gas supply integrated with a dense-phase pneumatic conveying system. This ensures that the powder remains in a nitrogen-rich environment from the feeding point to the final storage silo, eliminating any contact with ambient oxygen. The system’s design incorporates advanced pressure sensors, nitrogen flow regulators, and explosion-proof valves, all certified for hazardous environments. The successful deployment in Tver demonstrates headpowder’s capability to handle Russia pneumatic conveying challenges, especially in cold climates and remote locations.
The client, a rare earth metal producer in Tver, needed a reliable solution to transport rare earth oxide powder from a milling station to a blending silo, a distance of 85 meters. The powder has a bulk density of 1.2 g/cm³ and a median particle size of 10 microns, making it highly prone to electrostatic charging and agglomeration. Traditional mechanical conveyors were ruled out due to risk of dust leakage and batch contamination. The client specifically required a rare earth powder pneumatic conveying system that could maintain a nitrogen atmosphere with less than 1% oxygen content throughout the process. headpowder’s engineering team conducted a thorough site simulation using computational fluid dynamics (CFD) to optimize the conveying line diameter, air velocity, and nitrogen injection points. The final design uses a 150 mm diameter steel pipe with wear-resistant ceramic lining, rated for 6 bar pressure. A dedicated nitrogen generator supplies 99.99% pure nitrogen at a flow rate of 50 Nm³/h, with automatic replenishment triggered by oxygen sensors in the conveying line.
The core innovation of this nitrogen protection pneumatic conveying system lies in its dual-lock rotary valve and buffer hopper design. The rotary valve ensures continuous feeding without pressure loss, while the buffer hopper acts as a nitrogen purge chamber. Before powder enters the conveying line, the buffer hopper is flushed with nitrogen for 30 seconds, displacing any residual air. During operation, a pressure transmitter continuously monitors the line pressure, and a flow control valve adjusts the nitrogen supply to maintain a steady 0.2 bar overpressure relative to the atmosphere. This prevents air ingress even if a minor leak occurs. The system is also equipped with a nitrogen recovery unit that captures and recycles exhaust nitrogen, reducing operating costs. For the Tver project, the nitrogen consumption was measured at only 0.8 kg of nitrogen per kg of transported powder, which is well below the industry average of 1.5 kg/kg. This efficiency was achieved through precise pneumatic conveying case optimization, including variable-frequency drive (VFD) control of the blower and a self-cleaning filter at the discharge point.
Shandong Headpowder Engineering Co., Ltd. has a long track record in designing pneumatic conveying systems for abrasive and hazardous materials. The Tver project benefited from headpowder’s proprietary “HeadPowderFlow” software, which simulates particle behavior in dense-phase flow. This software allowed the engineering team to predict pressure drops, wear patterns, and nitrogen consumption with high accuracy, reducing on-site commissioning time by 30%. The entire system was prefabricated at headpowder’s workshop in Shandong, China, and shipped in modular containers to Tver. Local installation was supervised by headpowder’s field engineers, who also trained the client’s operators on system maintenance and emergency procedures. The project was completed within 14 weeks from contract signing to final acceptance, a timeline that exceeded the client’s expectations. This achievement reinforces headpowder’s reputation as a leading provider of Russia pneumatic conveying solutions, with a strong focus on Tver pneumatic conveying applications.
