Shanxi Yuncheng Lithium Battery Cathode Powder Positive Pressure Bolt Flow Pneumatic Conveying Proj

A lithium battery materials company located in Yuncheng, Shanxi, mainly produces and processes lithium battery cathode powder. The company's original conveying system used mechanical lifting and pneumatic hybrid conveying, but in actual operation, frequent issues such as material blockages, severe pipeline wear, and fluctuations in conveying efficiency occurred, seriously affecting production line continuity and final product quality.

Customer pain points

Lithium battery cathode powder features fine particle size, low density, easy agglomeration, and resistance to bumps. Traditional conveying methods have the following prominent pain points:
1) Frequent blockages: Materials tend to accumulate at curves and reducers, causing downtime and cleaning and affecting production capacity;
2) Powder damage: Mechanical lifting and high-speed airflow impact cause granules to break apart, increase fine powder, and lower quality in subsequent processes;
3) High energy consumption and maintenance costs: High air volume conveying results in higher energy consumption, and pipes wear out quickly and are frequently replaced;
4) Environmental pollution: Insufficient sealing leads to dust leakage, affecting the workshop environment and employee health.

Product solutions and advantages

To address these pain points, Head Powder customized a positive pressure thrombectomy pneumatic conveying system for this client. This system uses the principle of positive pressure dense phase conveying, allowing materials to move smoothly within the pipeline in a low-speed plug-like form, reducing the risk of material impact and wear from the source. At the same time, the system is equipped with intelligent pressure control and anti-blockage monitoring modules that can adjust conveying parameters in real time to effectively prevent blockages. The overall sealing design achieves dual protection of micro-negative and positive pressure, with zero dust leakage. Customer feedback after operation:
1) Conveying efficiency improved by about 30%, enabling continuous normal operation of the conveyor line;
2) Powder damage rate reduced to negligible levels, and the microstructure of the cathode material remains intact;
3) Energy consumption is reduced by about 25% compared to the original system, and the pipeline service life is more than doubled;
4) Workshop cleanliness has significantly improved, successfully passing environmental compliance inspections.

Head Powder has many years of engineering experience in the field of pneumatic conveying, especially accumulating numerous successful cases in positive pressure bolt flow conveying fine powder materials such as lithium battery cathode powders, ternary materials, and lithium iron phosphate. The successful implementation of the Yuncheng project in Shanxi once again validates the suitability of positive pressure throttle flow technology for high-value, fragile powders.
