Sichuan Dazhou lithium battery raw material silo pump dense phase long-distance conveying project

At a lithium battery materials production base in Dazhou, Sichuan, a pneumatic conveying system dedicated to transporting lithium battery raw materials has been operating normally for many years. The core of this system uses bin-pump dense-phase long-distance pneumatic conveying technology, which improves the loss and pollution issues of high-value lithium battery raw materials during transportation, making it a reference case for material transportation in the local new energy industry.

Case Summary

A certain company (hereinafter referred to as "the enterprise") is located in Dazhou, Sichuan, mainly engaged in the production and processing of lithium battery cathode and anode materials. During production, various powdered lithium battery raw materials (such as lithium carbonate, lithium iron phosphate, etc.) need to be transported from the storage area to the distant batching workshop. Due to plant layout limitations, the conveying distance exceeds 300 meters, and the material demands extremely high cleanliness and integrity. The company ultimately adopted a silo pump dense long-distance pneumatic conveying system, achieving fully enclosed, low-damage automated conveying.

Customer pain points

Before the project renovation, the company faced the following main issues:
1. Severe material damage: Traditional mechanical or rare-phase pneumatic conveying speeds are relatively high, causing lithium battery raw material particles to break apart, affecting subsequent battery performance.
2. Dust Pollution Risk: Powder materials are prone to dust during transportation, causing not only raw material waste but also environmental and occupational health risks.
3. High energy consumption for long-distance conveying: The original conveying method has low pneumatic ratio and high airflow speed, resulting in consistently high energy consumption and difficulty in controlling operating costs.
4. Heavy maintenance workload: Equipment wears out quickly, pipelines become frequently blocked, requiring frequent shutdowns for cleaning, which affects production efficiency.

Product advantages and solutions

To address these pain points, the company's Head powder silo pump dense phase long-distance pneumatic conveying system provides the following solution:
1. Dense Phase Conveying Technology: Utilizes high-concentration, low-speed material flow for conveying, allowing materials to enter a plug flow or fluidized state within the pipeline, effectively reducing the probability of particle collision and breakage, and protecting the original shape of lithium battery raw materials.
2. Fully Sealed Piping Design: The system is fully sealed from the feed port to the discharge port, with no dust leakage, meeting the lithium battery industry's requirements for clean production while reducing material loss.
3. Low Energy Consumption Operation: Reasonable gas-solid ratio configuration and optimized pipeline layout reduce unit energy consumption by more than 30% compared to traditional dilute-phase conveying, offering significant long-term operating cost advantages.
4. Intelligent control and low maintenance: Equipped with PLC automatic control system to monitor conveying pressure, material level, and other parameters in real time, with automatic blockage clearing function; Key components use wear-resistant materials to extend equipment lifespan and reduce downtime and maintenance.

System effectiveness

After commissioning, the company's lithium battery raw material transport damage rate is almost zero, dust emissions meet local environmental standards, and the continuous operation rate of the production line has improved. Customer feedback stated that the system is easy to operate, stable, and reliable, providing a replicable conveying solution for subsequent capacity expansion.
