Product Introduction
The spiral sand washing and recovery integrated machine is a highly efficient equipment that combines spiral sand washing, high-frequency linear screen dewatering, and a fine sand recovery system. It is primarily used in sand and gravel aggregate processing, mining, construction waste treatment, and related fields. Its core functions include cleaning sand and gravel through the spiral structure of the sand washer, while simultaneously recovering lost fine sand particles to minimize resource waste and improve both the quality and yield of processed materials.
Working principle
1、Material Feeding:
The sand-gravel mixture is fed into the trough of the spiral sand washer via a feeding device.
2、Spiral Sand Washing:
Spiral blades, driven by a motor, continuously tumble and friction-wash the materials to remove surface mud and impurities. During this process, water flows upward from the bottom of the trough, flushing away light impurities (e.g., mud and dust).
3、Dewatering and Recovery:
The cleaned sand and gravel are lifted by the spiral blades to a dewatering screen for vibratory dewatering, reducing moisture content.
A fine sand recovery system (e.g., hydrocyclones or fine sand recovery machines) further processes wastewater containing fine sand, separating and recycling particles ≥0.075mm.
4、Tailwater Treatment:
The wastewater is filtered through settling ponds or a water recycling system for reuse, achieving environmental protection and energy efficiency.Application Industries
1、Sand and Gravel Aggregate Processing:Cleaning natural sand and manufactured sand to enhance the cleanliness and gradation of construction-grade sand.
2、Mining:Processing sand and gravel from tailings (e.g., gold/iron ore) to recover valuable mineral particles.
3、Construction Waste Recycling:Washing recycled aggregates from construction debris for reuse in concrete production.
4、Water Conservancy Projects:River dredging, sand screening, and washing for sediment management.
5、Environmental Protection Industry:Sludge dewatering in wastewater treatment plants and resource utilization of solid waste.Performance Features & Advantages
1. High-Efficiency Washing & Recovery
Optimized spiral blade design ensures strong washing capability, with fine sand recovery rates reaching 85–95%, minimizing resource loss.
2. Energy Saving & Eco-Friendly
Equipped with a water recycling system to reduce water consumption.
Treated wastewater meets environmental standards for discharge.
3. Compact Structure, Small Footprint
Integrated design combines sand washing and recovery functions, saving installation space.
4. Stable Operation & Easy Maintenance
Critical components (e.g., spiral blades, screens) use wear-resistant materials (high-manganese steel, polyurethane).
Slurry pump flow parts adopt Cr26 wear-resistant steel, ceramics, or rubber for extended service life.
Modular design simplifies maintenance.
5. Strong Adaptability
Handles materials with high mud content and broad particle sizes (0.075–10mm), suitable for complex working conditions.
6. Automated Control
Supports PLC-based intelligent control for fully automated feeding, washing, and recovery processes, reducing labor costs.Typical Configurations
Core Components: Spiral sand washer, dewatering screen, fine sand recovery system (hydrocyclones + vibrating screen), water pump, settling pond.
Optional Features: Variable frequency speed control, intelligent monitoring system, customized screen apertures.Selection Guidelines
Choose models based on material properties (mud content, particle size).
Match equipment specifications to production capacity requirements.
Prioritize models with wear-resistant materials and intelligent control systems to reduce long-termTechnical Specifications Table
