Soil-Stone Separation Line

Soil-Stone Separation Line
1. Concrete and masonry debris processed into recycled aggregate
2. Metro and foundation excavation spoil treated for use as backfill
3. Usable stone and metal fractions recovered from mining waste
4. Dewatered and stabilized material turned into roadbase
5. Recyclable mineral feedstock separated from ceramic tile and plasterboard
6. Reclaimed asphalt pavement recycled into paving material

The Jushengding soil-stone separation line combines intelligent sorting with crushing technology to process construction waste, engineering spoil, mine tailings and other solid waste efficiently, maximizing resource recovery. Through multi-stage screening, crushing and washing, the line separates soil and stone fractions precisely by particle size, producing recycled aggregate and backfill that meet construction standards for road building, concrete production and other engineering uses.

Processing and Separation

The line separates material efficiently through several machines working in concert under intelligent control. Processing begins with even feeding from a chain plate feeder, whose variable-frequency drive adjusts feed rate intelligently to the material so downstream stages run steadily. The feed then enters the core sorting stage, where a purpose-designed disc-type soil-stone separator performs fine screening: its disc arrangement and vibration system separate sticky soil from stone effectively, with throughput 40% higher than conventional equipment.

During separation, heavy-duty conveyors form a three-dimensional material-flow network: inclined conveyors handle primary elevation, belt conveyors transfer the sorted fractions, and a return conveyor recirculates off-spec material for reprocessing. All conveyors run wear-resistant rubber belting with intelligent tensioning for stable transport under heavy loads. Multi-stage screening finally yields recycled aggregate and cleaned soil graded to the required particle sizes.

Feedstock Collection and Reuse

The Jushengding soil-stone separation line handles a wide range of mixed soil-and-rock feedstocks with complex compositions. It processes demolition concrete, brick and tile debris; excavation spoil and tunneling muck from construction works; and tailings left by mining operations. It also serves dewatering and stabilization of dredged river silt, sorting and recovery of renovation waste such as ceramic tile and plasterboard, and recycling of reclaimed asphalt pavement from road renewal. Built on a modular design, the line adjusts sorting parameters automatically to the feedstock and excels at heavily contaminated, complex material — an ideal solution for construction waste recovery, mine tailings reuse and engineering spoil treatment. Recycled aggregate from the line meets national construction material standards, turning waste soil into a genuine resource.

Economic Value of the Output

The output of the Jushengding soil-stone separation line serves engineering needs across many fields. Processed recycled aggregate meets construction material standards and goes directly into concrete batching and roadbed construction; sorted quality sand and stone feed precast component production; cleaned soil, once conditioned, suits landscaping and land rehabilitation projects; and finely classified mineral fractions provide base material for high-end building products. These recovered resources fully meet the relevant national industry standards, giving municipal construction, mine rehabilitation and environmental remediation a sustainable material supply — maximizing resource circulation and supporting green building and ecological development.
