A new energy materials company located in Ma'anshan, Anhui Province, mainly produces lithium battery cathode material powder. Due to the production line upgrade, lithium battery powder needs to be stably transported from the raw material silo to the batching workshop about 800 meters away. The powder has high hardness and fine particles. Traditional conveying methods suffer from severe pipeline wear, frequent pipe blockages, and dust leakage, seriously affecting production efficiency and workshop environment.

Customer pain points

Lithium battery powder particles are concentrated in particle sizes of 5~20 microns, with Mohs hardness of about 5~6. Conventional pneumatic conveying pipelines show obvious wear every 200 hours of operation and require shutdown and replacement; At the same time, powder tends to clump and frequently clogs at elbows, resulting in high manual cleaning costs; Additionally, insufficient sealing leads to fine dust leakage, posing risks to workshop cleanliness and employee health. The customer urgently needed a solution that combined high wear resistance, long-distance stable conveying, and environmental protection.

Head Powder Solutions

To address these pain points, Head Powder has customized a "Wear-Resistant Long-Distance Pneumatic Conveying System for Lithium Battery Powder" for the customer. The system uses the following core configurations:

• The inner wall of the pipeline uses a ceramic composite wear-resistant layer, which has more than eight times the wear resistance compared to ordinary steel pipes, eliminating the need for frequent replacement;
• Optimizing the elbow curvature radius and adding wear-resistant elbow liners effectively improves blockage issues; li>
• Fully enclosed negative pressure conveyor design, paired with high-efficiency dust collectors, enables dust-free operation; li>
• Equipped with intelligent pressure regulation and gas replenishment devices, it helps maintain stable pressure for horizontal + vertical pipelines up to 800 meters long, preventing powder settling.

After the project was put into operation, the equipment operated continuously for 2,000 hours without wear or clogging, the workshop dust concentration was below 1mg/m³, maintenance costs dropped by 70%, and conveying efficiency increased by 25%, earning high customer recognition.
