Hebei Handan lithium battery raw material centralized supply and sealed transportation project
A company undertook a centralized supply and sealed pneumatic conveying project for lithium battery raw material manufacturers located in Handan, Hebei. This project requires that raw materials such as lithium battery cathode materials and anode powder be transported from the raw material silo to multiple production stations in a sealed way, with conveying distances exceeding 150 meters. The materials are characterized by high purity, dust-raising properties, and moisture resistance. A company designed a positive pressure dense phase pneumatic conveying system for him, achieving full-process sealing, automated control, and low-pollution transfer.
Customer pain points
- Raw material contamination risk: Lithium battery raw materials are extremely sensitive to moisture and impurities. Traditional open-mouth conveying methods easily introduce dust and moisture, causing unstable batch quality.
- Dust and environmental pressure: During powder transportation, severe dust leakage not only causes material loss but also makes it difficult to meet local environmental emission standards.
- Low efficiency of centralized feeding at multiple stations: The original single-point conveying method required frequent pipeline switching and manual handling, resulting in low feeding efficiency and inability to monitor production data in real time.
- Equipment maintenance costs are high: Ordinary pneumatic conveying equipment does not adequately consider the wear resistance of lithium battery materials, resulting in frequent replacement of components such as bends and valves, which affects continuous production.
Product advantages
To address these pain points, a certain company offers the following solutions:
- Fully enclosed conveying structure: The system uses sealed pipelines from the feed inlet to the discharge port, combined with dehumidification drying and nitrogen protection measures, effectively isolating moisture from air and helping to stabilize raw material quality.
- Intelligent dust suppression and recycling: High-precision pulse dust collectors are installed at key points to recover and reuse fine dust generated during transportation, with emission concentrations below 5mg/m³, meeting lower emission requirements.
- Centralized control and path optimization: Through PLC and upper-level computer systems, multi-station automatic reversing, flow regulation, and fault alarms are achieved. Each device can simultaneously serve more than 6 feeding points, improving feeding efficiency by over 40%.
- Highly wear-resistant components and low-maintenance design: Uses chrome alloy wear-resistant bent pipes, ceramic-lined valves, and quick-release maintenance ports, significantly extending equipment lifespan and reducing annual maintenance costs by about 30%.
