Ternary cathode materials such as NCM and NCA are widely used in lithium-ion batteries for electric vehicles and energy storage. These fine, abrasive, and moisture-sensitive powders require a reliable and contamination-free conveying solution. Pneumatic conveying technology offers an enclosed, flexible, and efficient way to transfer materials from one process stage to another. Our customized ternary material pneumatic conveying systems are designed to meet strict purity, safety, and productivity requirements.

A typical system consists of a feeding device, conveying pipeline, receiving separator, dust collector, pressure or vacuum source, and control system. It can be configured as dilute phase or dense phase conveying. Dilute phase uses high velocity and low pressure, suitable for short distances and moderate capacities. Dense phase uses low velocity and high pressure to push plugs of material, reducing particle degradation and pipeline wear. For ternary materials, dense phase conveying is often preferred due to fragile particles and the need to minimize fines.

Every material handling site has unique constraints such as space, height, source and destination locations, throughput, and available utilities. Our design process begins with detailed analysis of particle size distribution, bulk density, moisture content, abrasiveness, and flowability. We also evaluate conveying distance, elevation change, number of bends, and discharge methods. Based on this data, we provide a custom layout and equipment selection, ensuring optimal gas velocity, solid-to-gas ratio, and line pressure. Systems can be skid-mounted or custom fabricated.

Key components are carefully selected for long service life and stable operation. Rotary valves or screw feeders provide controlled material input. The conveying pipe is made of stainless steel with a smooth inner surface and wear-resistant bends. For dense phase conveying, pressure tanks or blow pots are used. The receiving side is equipped with cyclone separators or bag filters. A pulse-jet dust collector ensures emission-free operation. The control panel uses PLC with HMI touchscreen, allowing easy monitoring of velocity, pressure, and sequence.

Ternary materials can be sensitive to moisture, contamination, and electrostatic charge. The conveying gas should be dried air or nitrogen, especially for oxygen-sensitive or hygroscopic materials. The entire system is sealed to prevent foreign particles from entering. Nitrogen gas provides an inert atmosphere to reduce oxidation or explosion risk. Grounding and anti-static measures are installed. Explosion relief vents and safety interlock valves are optional based on material safety data.

Using our customized system brings many benefits. The enclosed line prevents dust leakage and product contamination. Flexible routing saves floor space. Low-power design reduces energy consumption. Dense phase conveying protects particle morphology and ensures uniform product quality. Automation reduces labor costs and human errors. Purging procedures allow the system to clean itself for color changes or grade changes, contributing to a higher return on investment.

Our solutions are widely applied in lithium-ion battery cathode material production, including NCM, NCA, and other ternary precursors. The systems handle raw materials like lithium carbonate, nickel sulfate, cobalt sulfate, and manganese sulfate, as well as intermediate products like ternary hydroxides and final calcined cathode powders. They are used in mixing, calcination, crushing, sieving, packaging, and warehouse storage. They can also integrate with metal detecting, de-ironing, weighing, and batching systems to form a complete production line.
