This article presents a detailed case study of a specialized pneumatic conveying project executed for a lithium iron phosphate (LFP) powder processing facility located in Vladivostok, Russia. The project, titled "Russian Vladivostok Lithium Iron Phosphate Powder Inert Gas Closed Pneumatic Conveying Engineering Project," highlights the technical expertise of Shandong Haide Powder Engineering Co., Ltd., a leading provider of bulk material handling solutions. The system was designed to handle fine, reactive LFP powder under a controlled inert gas atmosphere, ensuring safety, product purity, and operational efficiency. The implementation involved a complete closed-loop pneumatic conveying system using nitrogen as the conveying medium, eliminating the risk of oxidation, dust explosion, or contamination. This project underscores the capability of Haide Powder to deliver turnkey solutions for international clients, particularly in challenging environments such as the Russian Far East.
The core products utilized in this project include a custom-designed inert gas closed pneumatic conveying system specifically engineered for lithium iron phosphate powder. The system integrates a dense-phase pneumatic conveying line, a nitrogen supply unit, a dust collector, and a rotating valve for precise material feeding. The conveying pipeline is made of stainless steel with internal surface treatment to minimize abrasion and powder adhesion. The project also features a PLC-based control system that monitors pressure, temperature, and gas flow in real time, ensuring stable operation under varying load conditions. The entire conveying process is sealed, preventing any leakage of inert gas or escape of fine powder. This case demonstrates Haide Powder's expertise in pneumatic conveying for lithium iron phosphate, inert gas closed conveying, and materials handling in the Russian market. The system has been successfully commissioned and is now operating at the client's facility in Vladivostok, handling LFP powder with a particle size of D50 around 5 microns.
Shandong Haide Powder Engineering Co., Ltd., abbreviated as Haide Powder, is a professional engineering company headquartered in Shandong, China. The company specializes in the design, manufacturing, and installation of pneumatic conveying systems, dust collection equipment, and related bulk material handling solutions. With years of experience in both domestic and international projects, Haide Powder has established a strong reputation for delivering reliable, high-performance systems for industries such as battery materials, chemicals, food, and pharmaceuticals. The company's engineering team has extensive knowledge of handling fine, reactive, and hazardous powders, including lithium iron phosphate, lithium carbonate, and other cathode materials. Haide Powder's commitment to quality and safety is reflected in its adherence to international standards, such as ISO 9001 and ATEX directives for explosion-proof environments. For the Vladivostok project, the company provided full technical support, from conceptual design to on-site commissioning and training.
The project is located in Vladivostok, a major port city in the Russian Far East, which serves as a strategic hub for industrial and logistics activities. The client, a leading manufacturer of lithium iron phosphate battery materials, required a safe and efficient conveying system to transport LFP powder from the milling stage to the blending and packaging units. The key challenges included the fine particle size of the powder, its tendency to oxidize when exposed to air, and the need to operate in a cold climate with potential condensation issues. The client mandated the use of inert gas (nitrogen) as the conveying medium to maintain a low-oxygen environment throughout the process. Additionally, the system had to meet strict environmental regulations regarding dust emissions and noise levels. Haide Powder's solution met all these requirements by designing a closed-loop pneumatic conveying system with a nitrogen recirculation and purification unit, ensuring that the oxygen concentration remained below 2% at all times.
The pneumatic conveying system for the Vladivostok project is a dense-phase, low-velocity type, which minimizes particle degradation and reduces energy consumption. The conveying capacity is 2 tons per hour, with a conveying distance of 80 meters and a vertical lift of 15 meters. The system uses nitrogen as the inert gas, supplied from a liquid nitrogen storage tank and vaporizer. The nitrogen is recycled through a filter and a pressure control valve to maintain a slight positive pressure inside the pipeline. The material feed point is equipped with a rotary valve with a special seal to prevent gas leakage. At the discharge point, a cyclone separator and a pulse-jet bag filter capture the powder, while the nitrogen is returned to the supply line. The entire system is controlled by a Siemens PLC with a touchscreen HMI, allowing operators to monitor key parameters and adjust settings remotely. The system also includes an emergency shutdown feature and a fire suppression system in case of abnormal conditions.
The installation of the pneumatic conveying system in Vladivostok was completed within six months, including civil works, piping, electrical wiring, and automation. Haide Powder dispatched a team of experienced engineers to supervise the installation and provide on-site training to the client's operators. The commissioning phase involved leak testing, pressure testing, and trial runs with inert gas to ensure that the oxygen content remained below the threshold. The system achieved a conveying efficiency of 98% with minimal powder breakage, meeting the client's quality standards. The client reported that the system operated smoothly during the first three months of production, with zero downtime related to the conveying system. The inert gas consumption was within the expected range, and the dust emission levels were below 1 mg/Nm³, far exceeding local environmental regulations. This successful project has strengthened the partnership between Haide Powder and the Russian client, paving the way for future collaborations on similar projects.
