Customized Sand and Gravel Washer Factory

SINOU Sand and Gravel Washer is a professional wet-type cleaning equipment specially developed for aggregate purification, widely used together with Rotary Concrete Reclaimer and Vibratory Concrete Reclaimer in concrete recycling lines. It is mainly applied to remove mud, dust, organic impurities and residual cement on the surface of recycled sand and stone.

By means of high-pressure water flushing and mechanical stirring, it greatly improves aggregate cleanliness and grading quality. The treated sand and gravel can fully meet the raw material standards of commercial concrete, turning waste residual concrete into high-quality reusable resources.

This equipment is an essential supporting unit to upgrade the overall utilization value of concrete recycling systems.

Working Principle & Structural Advantages

This sand and gravel washer adopts combined mechanical agitation and circulating water flushing technology to realize continuous cleaning operation.

(1) Working Principle

Recycled aggregate from the concrete reclaimer is fed into the washing tank. The built-in stirring impeller continuously rolls and turns over materials to separate mud and dirt attached to sand and gravel. Meanwhile, the circulating water system sprays high-pressure water flow for thorough rinsing. Light impurities and muddy water flow out with the water and enter the sedimentation system for recovery and reuse, while clean sand and gravel are discharged from the designated outlet to complete the whole washing process. The whole procedure runs continuously and circularly.

(2) Core Structural Highlights

● Reinforced stirring impeller: Made of high wear-resistant alloy steel, it resists long-term friction and impact from aggregates, with strong stirring capacity and no easy deformation.

● Large-capacity water tank: Optimized water flow channel design ensures full contact between materials and water, and avoids material deposition.

● Integrated circulating water system: Realizes water recycling, reduces water consumption and complies with environmental protection regulations.

(3) Matching Performance

It can be seamlessly connected with upstream sand-gravel separation equipment and downstream aggregate conveying systems. Matched with supporting chutes and HDPE pipelines, it forms a complete set of aggregate recycling, cleaning and conveying production lines, with stable overall operation and low failure rate.

Product Features & Performance Highlights

1. Excellent cleaning effect: Dual action of mechanical stirring and high-pressure water flushing effectively remove surface mud and cement residues, and the cleanliness of finished aggregates reaches industrial standards.

2. Super wear resistance: Key moving parts adopt wear-resistant strengthening process, adapting to long-term continuous operation in harsh working conditions.

3. Water-saving & eco-friendly design: Equipped with complete water circulation and sedimentation facilities, the water recycling rate is high, effectively reducing water resource waste and sewage discharge.

4. Wide adaptability: Suitable for cleaning recycled aggregate of different particle sizes, and can work normally for dry, wet and mixed materials.

5. Simple operation & low maintenance: Equipped with automatic control system, it supports unattended operation; the open structure is convenient for daily inspection and residue cleaning.

6. Compact layout: Reasonable structural design saves installation space, easy to integrate into existing concrete recycling production lines.

2. Frequently Asked Questions

Q: Can this sand and gravel washer work with concrete reclaimers?

A: Absolutely. It is specially designed as supporting equipment for concrete recycling systems. It can be directly connected to the discharge port of rotary and vibratory concrete reclaimers to realize one-stop separation and cleaning of residual concrete, which is the standard configuration for high-standard recycling lines.

Q: What is the mud removal capacity of the equipment?

A: The combined stirring and flushing structure can thoroughly strip surface mud and cement clumps. The mud content of cleaned aggregate can be controlled within the standard range, fully meeting the production requirements of ready-mixed concrete.

Q: Does the equipment consume a lot of water during operation?

A: No. The machine is equipped with an independent circulating water system. After muddy water is precipitated, the clear water is reused for flushing. The actual fresh water consumption is very low, which is energy-saving and environmentally friendly.

Q: Is the equipment suitable for large-volume continuous production? A: Yes. The whole machine is designed for heavy-duty continuous operation. The large tank body and high-power drive system can adapt to long-hour, large-flow aggregate cleaning work for large mixing stations.

Q: Can the equipment be customized according to on-site conditions?

A: We provide personalized customization including tank volume, processing capacity, installation size and power configuration to meet the layout demands of different production lines.

Routine Maintenance

1. Regularly inject lubricating oil into all bearing positions and transmission components, and check whether the transmission runs flexibly and stably.

2. Inspect all fastening screws and bolts regularly, and tighten loose parts in a timely manner to prevent vibration and displacement.

3. Clean residual sand, gravel and cement dirt inside the tank and on the stirring impeller after each shift to avoid material solidification and blockage.

4. Clear sludge and sediment in the circulating water tank and peripheral water channels every day to ensure unobstructed water circulation.
