Any application requiring separation of light versus heavy fractions, including PP regrind, paper-plastic streams, or biomass fuel preparation, can benefit from the adjustable airflow design.” } }, { “@type”: “Question”, “name”: “What routine maintenance is required?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Operators mainly inspect fan bearings, rotary valve blades, and dust collection points. With proper filtration, the system runs months between planned service stops.” } }, { “@type”: “Question”, “name”: “What throughput ranges are available and how is sizing determined?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Standard systems cover roughly 300 to 3000 kg/h. Final sizing depends on polymer type, bulk density, flake geometry, moisture, and contaminant loading. Column cross-section, height, number of stages, and blower curve are selected to meet purity and pressure-drop targets.” } }, { “@type”: “Question”, “name”: “How is dust captured to meet local emission requirements?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “The light fraction is routed to a cyclone and then a downstream filter such as a baghouse or cartridge collector. Sealed ducting and slight negative pressure prevent fugitive dust. Optional HEPA final stage or spark arrestor can be added for stricter regulations.” } }, { “@type”: “Question”, “name”: “Is it washdown-ready and what are product-contact materials?”, “acceptedAnswer”: { “@type”: “Answer”, “text”: “Product-contact surfaces are typically stainless steel, with 304 as standard and 316 optional. Clean-out doors and inspection windows are included, while washdown packages and CIP nozzles can be specified for high-hygiene applications.” } } ] } { “@context”: “https://schema.org”, “@type”: “VideoObject”, “name”: “Zig-Zag Air Classifier Demonstration”, “description”: “How a zig-zag air classifier removes labels, dust, and fines from plastic flakes using controlled airflow.”, “thumbnailUrl”: “https://www.recyclemachine.net/wp-content/uploads/2026/09/zig-zag-air-classifier-video-poster.webp”, “embedUrl”: “https://www.youtube-nocookie.com/embed/OgBP2xTTNVg”, “uploadDate”: “2025-01-30T11:15:58Z” }
