What Makes Up a Complete Solid Waste Screening, Air Sorting and Magnetic Separation Line? | Jushengding
As zero-waste city programs and high-value solid waste recovery advance, mixed streams — construction waste, aged landfill waste, industrial residues, household waste and renovation debris — cannot be recovered efficiently by crushing alone. Graded screening, ferrous removal and light/heavy separation are what raise recycled-material purity and price. Jushengding specializes in sorting equipment and custom lines, offering five core machines — chain plate feeder, multiple-frequency screen, trommel screen, magnetic separator and positive/negative-pressure wind sifter — that combine into automated sorting lines, separating soil, aggregate, metal and light/heavy fractions precisely so every recovered stream reaches its full value.
1. The Sorting Line's Core Equipment in Detail (Full Jushengding Range)
1. Chain Plate Feeder — the line's stable feeding core
The front-end metered feeder, designed for lumpy, high-moisture mixed feed containing sharp contaminants.
High-strength wear-resistant chain plates — impact-proof, wear-proof, no slipping, no blockage;
Variable-frequency speed control feeds evenly to match downstream load, preventing overload shutdowns;
Suited to construction waste, aged waste, industrial solid waste, shredded bulky waste and run-of-mine feed. The chain plate feeder keeps the whole line running continuously — the foundation of efficient sorting.
2. Multiple-Frequency Screen — grading and de-contamination in one
Combining multi-deck screening with a self-cleaning structure, it offers high throughput, no blinding and precise grading — ideal for fast classification of mixed solid waste.
Grades several particle sizes at once, splitting the feed into fine, medium and coarse fractions;
Self-cleaning anti-blinding design copes extremely well with sticky, soily or fibrous material;
Widely used in pre-processing construction waste, renovation debris, household waste and industrial residues. Compact and efficient, it is the screening machine of choice for small and mid-sized sorting projects.
3. Trommel Screen — for high-clay feeds
With its rotating drum body the trommel screen runs smoothly and quietly, tolerates sticky, wet feed and resists blinding — the ideal screen for solid waste with high soil content.
Automatic grading by aperture: fine soil, spoil and powder pass through the mesh while oversize material travels forward;
Suited to construction spoil, weathered mine feed, aged landfill waste, compost feed and de-soiling of aggregate;
The screened fine soil serves backfill, brickmaking and landscaping, while oversize material moves on to the next sorting stage. Low failure rates and long service life make it standard equipment on industrial-scale projects.
4. Magnetic Separator — automatic ferrous recovery
Mixed solid waste routinely carries nails, rebar, wire and sheet iron — magnetic metal that degrades recycled-material quality and damages crushers and screens. Jushengding's magnetic separator uses a high-strength magnetic roller to capture and discharge ferrous metal automatically, with high efficiency and stable operation.
Protects downstream equipment, reducing wear and failures;
Recovers clean steel scrap for direct resale;
Suited to construction waste, industrial residues, shredded appliances, mixed metal and household waste. The magnetic separator is essential ferrous-removal equipment on any recovery line.
5. Positive/Negative-Pressure Wind Sifter — high-precision light/heavy separation
Using airflow and density differences, the wind sifter parts heavy from light fractions precisely — the key machine for raising recycled-material purity and value.
Heavy fraction: stone, glass, rigid plastic and metal lumps settle automatically;
Light fraction: film, paper, fabric, foam and wood chips are carried off and collected by the airstream;
High sorting precision, adjustable airflow, low energy use, sealed and dust-free;
Widely used in RDF/SRF fuel preparation, plastics purification, waste recovery and industrial solid waste processing. It lifts material quality markedly, letting each fraction sell separately for double the return.
2. Feedstocks Suited to Jushengding Sorting Lines
Construction waste, renovation debris and mixed demolition material
Aged waste and landfill-mining mineralized waste
Industrial solid waste, light residues, offcuts and mixed scrap
Household waste and incinerator slag
Run-of-mine feed, sand and aggregate, clay-bearing stone
Shredded plastics, mixed metal and recovered-material sorting
3. Why Choose Jushengding Sorting Equipment?
