In the new energy sector, ultrafine powders such as ternary lithium and lithium iron phosphate (particle size ≤10μm) possess high specific surface areas, making them highly prone to forming “powder-air mixtures” when exposed to ambient air. Conventional packaging equipment, constrained by outdated degassing technologies, typically leaves residual air rates exceeding 15% within sealed bags. During storage and transportation, even a mere 10°C temperature increase causes internal bag pressure to surge by 0.03MPa, resulting in ton-bag inflation breakage rates as high as 18%. One nano-silicon powder manufacturer suffered a single-batch loss of 50 tons of raw material due to this issue, with product purity plummeting from 99.9% to 98.5%, ultimately costing them a critical order from a leading battery producer.
The core innovation lies in its three-stage deep degassing system: Initially, spiral agitation performs preliminary degassing, expelling 60% of free air; subsequently, a -0.095MPa high-vacuum degassing module removes 38% of adsorbed air; finally, 50Hz high-frequency pulse vibration eliminates the remaining 2% trapped in micropores, achieving a residual air rate below 2%. Complemented by a dynamic pressure balance valve that continuously monitors intra-bag pressure, the system automatically adjusts exhaust volume in response to drastic environmental temperature fluctuations, preventing powder compaction and addressing the root cause of bag inflation.
Tailored for the stringent demands of the new energy industry, the machine integrates dual-screw gentle feeding technology to minimize electrostatic dust generation during high-speed powder conveyance (dust leakage reduced to <0.1%). Its servo weighing system ensures ±0.1% consistent measurement accuracy, fully meeting lithium battery materials’ purity and ratio requirements. After adopting this solution, a lithium iron phosphate enterprise reduced bag inflation rates from 18% to 0.5%, cut raw material losses by 90%, and secured entry into CATL’s supply chain.
