Project Case of Dense Phase Pneumatic Conveying of Spodumene Ore Powder for a Mining Enterprise in Nantong, Jiangsu

This article presents a comprehensive case study on the dense phase pneumatic conveying system designed and implemented for a lithium spodumene mineral powder processing facility owned by a mining enterprise in Nantong, Jiangsu Province. The project highlights the advanced capabilities of Shandong Headpowder Engineering Co., Ltd. in delivering reliable, long-distance, and highly efficient dense phase conveying solutions for fine mineral powders. The entire content is structured to provide detailed technical insights, operational benefits, and practical application references for engineers, project managers, and decision-makers in the mining and mineral processing industry.

Project Background and Client Requirements

The client, a prominent mining enterprise based in Nantong, Jiangsu, operates a lithium spodumene ore processing plant that produces a significant quantity of fine mineral powder as a byproduct. The lithium spodumene mineral powder, with a particle size distribution ranging from 150 to 500 mesh, needed to be transported from the grinding section to a distant storage silo located approximately 800 meters away. The existing manual handling and dilute phase pneumatic conveying methods were inefficient, causing high energy consumption, pipeline wear, and frequent blockages. The client required a robust, energy-saving, and low-maintenance solution capable of conveying the abrasive and cohesive powder over a long distance without degradation of particle quality. After evaluating several suppliers, the client selected Shandong Headpowder Engineering Co., Ltd. (headpowder) due to its proven track record in dense phase pneumatic conveying technology and its ability to tailor the system to the specific characteristics of lithium spodumene mineral powder.

Core Product: Dense Phase Pneumatic Conveying of Lithium Spodumene Mineral Powder

The primary product deployed in this project is a custom-engineered dense phase pneumatic conveying system designed specifically for lithium spodumene mineral powder. Dense phase conveying, also known as high-density or plug flow conveying, operates at low gas velocities and high solid-to-air ratios, which minimizes particle attrition, reduces pipeline erosion, and significantly lowers energy consumption compared to dilute phase systems. For this application, the system uses a positive displacement blower to generate a controlled pressure that pushes the powder in a series of dense plugs through a seamless steel pipeline. The key advantage of dense phase conveying for lithium spodumene mineral powder is its ability to handle the fine, cohesive, and slightly abrasive nature of the material without causing segregation or degradation. The system includes a specially designed feed hopper with a rotary valve, a pressure vessel, a compressed air supply unit, and a series of diverter valves to direct the material to multiple storage points. The long-distance dense phase conveying capability of this system ensures that the lithium spodumene mineral powder can be transported over 800 meters with minimal pressure drop and consistent flow, making it ideal for large-scale mining operations where centralized storage is required far from the production area.

Technical Highlights of the Long-Distance Dense Phase Conveying Solution

The long-distance dense phase conveying system installed at the Nantong facility incorporates several advanced features that optimize performance and reliability. First, the pipeline routing was carefully designed to minimize bends and elevation changes, which are critical for maintaining plug stability over long distances. The system uses a combination of straight sections and gentle-radius bends to reduce pressure loss and prevent material accumulation. Second, the control system employs a real-time pressure monitoring and flow regulation algorithm that adjusts the air supply based on the actual material density and pipeline conditions. This adaptive control ensures that the dense phase plugs remain intact even when the material properties vary slightly due to changes in moisture content or particle size distribution. Third, the system includes a dedicated pipeline purging and cleaning mechanism that automatically removes any residual material after each batch, preventing blockages and contamination. The overall design results in a conveying capacity of up to 15 tons per hour, with a power consumption of only 0.6 kWh per ton of material, representing a 40% reduction compared to the previous dilute phase system. The long-distance dense phase conveying solution also features a modular lay-out, allowing for future expansion or relocation without major modifications.

Case Study Example: Successful Implementation and Operational Results

This case study provides a tangible reference for similar projects in the mining and mineral processing industry. The lithium spodumene mineral powder dense phase conveying system was commissioned in March 2024 and has been operating continuously for over eight months without any unscheduled downtime. During the initial testing phase, the system achieved a 99.5% material recovery rate, with negligible dust emissions and no measurable change in particle size distribution. The client reported a 35% reduction in overall maintenance costs, as the dense phase conveying system eliminated the need for frequent filter replacements and pipeline repairs that were common with the previous dilute phase system. The long-distance conveying capability allowed the client to consolidate storage operations, reducing the footprint of the material handling area by 50%. The system also integrated seamlessly with the existing plant control system via a Modbus RTU interface, providing real-time data on material flow, pressure, and energy consumption. The success of this project has led to a follow-up order for a second conveying line to serve a new expansion at the same facility. The case study clearly demonstrates the advantages of dense phase pneumatic conveying for lithium spodumene mineral powder, especially in long-distance applications where reliability and efficiency are paramount.
