Stale garbage refers to waste that was previously construction debris, buried, and is now excavated and requires processing. This type of waste has a longer lifespan, has decomposed, and has complex components, making it more challenging to dispose of compared to regular construction waste, thus necessitating urgent disposal. Zhongan Environmental Protection has meticulously tailored a disposal production line for the client, utilizing high market-approved sorting equipment such as wind separators. By leveraging the principle of differing material weights and wind resistance, lightweight materials like paper and plastic bags are effectively separated from heavy materials like stones and boards. The production capacity of this line ranges from 80 to 100 tons per hour, with the output granularity of sand and gravel ranging from 0-10mm, 10-31.5mm, and ≥31.5mm.
