The Soil and Stone Separation Equipment for Mining from Qingzhou Mingxu Supply Chain is a dry and wet dual-purpose screening machine designed for separating soil, clay, sand, and stones. It uses a roller disc screening structure, which allows it to process wet and sticky materials without water washing. The machine is built for continuous operation with large output and is used in river sand grading, raw ore processing, weathered material treatment, construction waste recycling, and coal gangue handling.
The equipment is intended as supporting machinery for sand and stone processing lines and mining projects. Its roller design reduces blockage compared with traditional vibrating screens, making it suitable for high-moisture and high-clay feed materials.

1. Anti-blockage capability. The synchronized rotating discs continuously break apart wet clay and silt, preventing the clogging that commonly affects vibrating screens when handling sticky materials.
2. High throughput and continuous operation. The integrated roller conveying and screening design allows even feeding and smooth discharge. It can run 24 hours a day for aggregate pre-processing.
3. Wear-resistant components and low maintenance. Thickened wear-resistant discs are used to withstand impact and abrasion. The simple structure makes inspection and replacement of bearings and chains straightforward.
4. Dry and wet dual-use, wide material compatibility. No water washing is needed. The machine handles weathered rock, river raw sand, construction waste, coal gangue, and mine mixtures, making it suitable for sand plants, solid waste recycling, and mining operations.
5. Adjustable structure. The number of rollers and disc gaps can be modified according to material particle size and production requirements, allowing the machine to fit into existing processing lines.
The Soil and Stone Separation Equipment for Mining is equipped with multiple linked rollers fitted with discs. The motor drives all rollers to rotate synchronously through a reducer. Mixed material is fed from the front inlet onto the roller screening area. Fine soil and silt drop through the gaps between discs, while larger stones and aggregates are pushed forward by the rotating discs and discharged from the rear outlet. The constant rotation of the discs breaks sticky wet clay, reducing the chance of blockage. This process enables continuous mud-stone separation without water washing.
1. Pre-operation inspection:
1.1 Check the frame, rollers, and discs for deformation, wear, or jammed debris.
1.2 Inspect the oil level of the motor and reducer, and adjust the tension of transmission chains.
1.3 Clear the machine and discharge area to avoid blockage from large hard stones.
1.4 Confirm wiring and safety covers are intact. Run a no-load test before feeding.
2. Feeding and screening operation:
2.1 Start the machine and let it idle for 2 minutes to check synchronous rotation of rollers.
2.2 Feed mixed material evenly; avoid dumping oversized stones all at once.
2.3 Observe the screening result and adjust feeding speed based on material humidity and mud content.
2.4 Reduce feeding volume if sticky material accumulates; the self-rotating discs will clear clay automatically.
3. Shutdown and daily maintenance:
3.1 Stop feeding first, then cut off power after all material inside is fully discharged.
3.2 Clean residual clay and gravel between discs to prevent jamming after drying.
3.3 Lubricate chains and bearings, and replace severely worn discs in a timely manner.
3.4 Cover the machine to protect it from rain and dust when not in use.
Applicable materials:
1. Mining materials: weathered rock, mountain topsoil, mixed raw ore, coal gangue.
2. Sand and gravel: river cobble, raw mountain sand, mud-containing stone, river mixed aggregate.
3. Solid waste: construction waste, demolition soil, broken stone muck.
4. Engineering soil: tunnel muck, foundation silt mixed with stones, backfill mixture.
Typical scenarios:
1. Aggregate plants: pre-screening raw material to separate soil and qualified stones for better finished sand quality.
2. Open-pit mines: removing surface covering soil in advance to reduce the workload of sand washing machines.
3. Construction waste recycling: separating muck from recyclable broken stone aggregate.
4. River dredging and sand mining: separating silt from cobbles to purify stone materials.
5. Coal processing: sorting soil and coal lumps to reduce impurity content.
6. Infrastructure earthwork: classifying tunnel and foundation muck mixed with stones.
The main structure and drive components are covered for 12 months or 1,000 working hours, whichever comes first. Wear parts such as discs and chains are not included in the warranty. Replacement parts can be supplied; freight and installation labor are the customer's responsibility.
Q1: What is the maximum moisture content the separator can handle?
A1: The machine is designed for wet and sticky materials, including clay with high moisture content. The rotating discs continuously break up wet clay, so blockage is rare even when the feed is very wet. For extremely liquid slurry, however, a pre-dewatering step may still be recommended.
Q2: Can the disc gap be adjusted to change the separation size?
A2: The disc gap is set during manufacturing based on the required separation size. While it is not adjustable during operation, the roller and disc configuration can be customized at the order stage to match specific particle size ranges. We recommend providing a sample or target size specification before production.
Q3: What are the main wear parts and how often do they need replacement?
A3: The main wear parts are the discs and drive chains. Replacement frequency depends on the abrasiveness of the feed material. Under normal conditions with river sand or construction waste, discs may last several months to a year. Regular inspection is recommended, and spare discs should be kept for continuous operations.
Q4: Does the machine require a water supply or washing system?
A4: No. The separator works without water, which makes it suitable for areas with limited water resources or for dry processing lines. It separates fine soil from stone using mechanical action only.
