鋰電行業(yè)在生產(chǎn)過程中，涉及大量粉體物料的輸送，這些粉體物料具有粒度小、易飛揚(yáng)、易受潮等特點(diǎn)，給輸送過程帶來了諸多挑戰(zhàn)。傳統(tǒng)的機(jī)械輸送方式往往存在物料泄漏、污染環(huán)境、維護(hù)困難等問題，嚴(yán)重影響了生產(chǎn)效率和產(chǎn)品質(zhì)量。

　　The lithium battery industry involves the transportation of a large amount of powder materials in the production process. These powder materials have the characteristics of small particle size, easy flying, and moisture resistance, which brings many challenges to the transportation process. Traditional mechanical conveying methods often suffer from problems such as material leakage, environmental pollution, and difficult maintenance, which seriously affect production efficiency and product quality.
