Lithium hydroxide powder is a critical raw material for lithium-ion batteries, lubricating greases, ceramics, glass, and chemical processes. As demand for electric vehicles grows, efficient and safe powder handling is essential. Pneumatic conveying provides a closed, dust-free, and automated method to move lithium hydroxide from receiving to silos, process equipment, and packaging lines. Our customized systems address its fine particle size, hygroscopic nature, and explosion risk.

Handling lithium hydroxide powder presents engineering challenges. The fine powder easily becomes airborne, requiring fully sealed systems to avoid contamination and product loss. It also absorbs moisture, leading to caking and pipeline blockage. Electrostatic charges can cause material buildup and increase ignition risk. Our systems use dried compressed air or nitrogen with strict humidity control and proper grounding. Every component is selected to maintain smooth flow and minimize particle degradation.

We provide both dilute phase and dense phase pneumatic conveying. Dilute phase suspends powder in a high-velocity gas stream, suitable for short distances and less fragile materials. For lithium hydroxide, dense phase conveying is often recommended because low velocity and high pressure gently push material, reducing attrition, pipe wear, and energy use. Depending on layout, we can combine positive pressure and vacuum systems. Our engineers analyze the complete material path, including intake, transfer, storage, weighing, and discharge, to deliver an optimized solution.

A complete lithium hydroxide conveying system includes a feeding device, such as a rotary airlock or pressure vessel, to introduce powder into the line. A blower or compressor generates the required gas flow and pressure. The pipeline is designed with proper bends, diameters, and lengths to prevent blockage and pressure drops. At the destination, a cyclone separator or bag filter recovers the powder from the conveying gas. Storage silos are equipped with level sensors, dust collectors, and discharge aids. All components are made of stainless steel or compatible materials to avoid corrosion. Automatic control panels and monitoring systems allow real-time operation and adjustment.

Safety is a top priority in lithium hydroxide powder handling. The dust can form explosive mixtures in air, so all equipment incorporates explosion protection. We implement explosion venting, flame-retardant filters, pressure monitoring, static grounding, and nitrogen blanketing where required. The system is designed to minimize dust accumulation on ledges and inside pipes. Emergency shutdown interlocks are integrated with the plant control system. This approach protects personnel and equipment while maintaining high production efficiency.

Our systems offer many benefits. The enclosed design prevents leakage, reduces waste, and creates a cleaner workplace. Automation reduces manual labor and improves consistency. Modular construction allows easy expansion. High-efficiency filters recover almost all powder, and gentle conveying preserves particle integrity. Energy-optimized drives lower operating costs. These systems are widely used in battery cathode material production, such as NMC and NCA, and in chemical, ceramic, glass, and metallurgical industries. Capacities range from hundreds of kilograms to several tons per hour, with custom indoor or outdoor designs.
