Sichuan Suining lithium salt powder moisture-proof and anti-caking sealed conveying system project

A lithium salt manufacturer located in Suining, Sichuan, needs to transport lithium salt powder from the warehouse to multiple production process units during daily production. Because lithium salt powder is highly hygroscopic, prone to caking when damp, and the production environment requires strict dust control, traditional mechanical conveying methods cannot meet the needs of moisture prevention and dust leakage.

Customer pain points

The client faces the following core issues:

• During transportation, lithium salt powder easily absorbs moisture from the air, leading to caking and pipeline blockages, which affects production continuity and product quality.
• Dust leakage from open or semi-open conveyor systems not only causes material waste but also poses safety hazards, and does not meet environmental protection regulations.
• Frequent manual intervention, low conveying efficiency, high maintenance costs, and inability to meet the needs of automated production line upgrades.

Solution

Head Powder was tailor-made for this customerEnclosed pneumatic conveying system, integrating the following key designs:

• Fully enclosed pipeline transport prevents dust leakage, isolates materials from external air, and effectively prevents moisture absorption and caking.
• Equipped with dehumidification and temperature control auxiliary devices, it helps dry the carrier gas and suppresses moisture intrusion at the source.
• It uses a micro positive pressure conveying method, combined with automatic blockage cleaning and discharge design, supporting continuous normal operation.
• PLC intelligent control system enables remote start/stop, real-time monitoring of conveying pressure and flow, reducing manual intervention.

After the system was put into operation, the caking rate during lithium salt powder transport dropped by over 90%, dust emission concentrations remained below industry standard limits, production efficiency improved by about 35%, and operation and maintenance costs dropped significantly.
