Overview
The XSHS Series Fine Sand Recovery Machine & Fine Sand Recovery–Dewatering Integrated System is a complete, self-contained slurry processing unit engineered for efficient separation, recovery, and deep dewatering of fine solid particles from liquid–solid mixtures. Unlike conventional sand washing equipment that focuses primarily on cleaning, the XSHS system is purpose-built for fine particle recovery, targeting valuable solids—typically fine sand above 0.075 mm—that are traditionally lost to tailings water or settling ponds.
In modern aggregate, mining, and mineral processing operations, the loss of fine sand not only reduces product yield but also disrupts particle size distribution, increases environmental pressure, and raises water treatment costs. The XSHS system addresses these challenges by integrating functions that were once spread across complex, space-consuming process chains—such as hydrocyclones, dewatering screens, and large settling ponds—into a single, modular recovery unit.
Whether installed as a retrofit to an existing wet processing line or incorporated into a new dry sand production system, the XSHS series acts as a value-enhancing and environmental compliance module, improving both economic returns and operational sustainability.

Working Principle
The XSHS system operates as a closed and coordinated process consisting of slurry pumping, centrifugal classification, and high-frequency dewatering.
Slurry containing fine solids is first delivered to the system by a dedicated slurry pump unit, which provides stable pressure and flow. The pressurized slurry then enters a hydrocyclone group, where centrifugal force rapidly separates solids based on particle size and density. Coarser fine particles are discharged through the underflow, while water and ultra-fine particles exit via the overflow.
The hydrocyclone underflow, characterized by high solid concentration, is directed onto a high-frequency linear dewatering screen. Through low-amplitude, high-frequency vibration, the fine sand moves progressively along the screen surface while excess water and ultra-fine particles are removed. The result is a free-flowing fine sand product with low moisture content, suitable for direct stacking, blending, or conveying.
Meanwhile, the hydrocyclone overflow is collected and guided into an integrated return-water tank, where further clarification occurs before reuse or controlled discharge. This configuration significantly reduces downstream settling pond load and supports efficient water recycling.
Main Components
Slurry Pump Unit
Serves as the feed power source of the system. Designed for abrasive slurry handling, typically equipped with variable-frequency control to regulate flow and pressure under different operating conditions.
Hydrocyclone Cluster
The core classification component, manufactured from wear-resistant polyurethane or ceramic materials. Multiple cyclones can be configured in parallel to match processing capacity and achieve stable separation efficiency.
High-Frequency Linear Dewatering Screen
Receives cyclone underflow and performs rapid dewatering and desludging. Screen media and vibration parameters are optimized specifically for fine sand recovery.
Overflow Distributor and Return-Water Tank
Collects cyclone overflow and ensures smooth water flow, reducing turbulence and improving clarification efficiency. Enables reuse of process water.
Integrated Steel Frame and Electrical Control System
All components are mounted on a single heavy-duty steel skid, ensuring compact layout, easy transport, and fast installation. The electrical system supports centralized control, interlocking operation, and condition monitoring.
Optional Discharge Chute or Conveyor Interface
Allows recovered fine sand to be directed to finished product stockpiles, blending systems, or downstream conveyors.
Applications
Aggregate and Sand Production (Primary Application)
Retrofit of traditional wet sand washing lines to recover lost fine sand and increase yield by 10–25%.
Particle size optimization to meet concrete and asphalt specifications.
Core environmental solution for dry sand production systems handling crusher fines.
Mining and Mineral Processing
Recovery of valuable fine particles from tailings streams.
Preliminary slurry thickening and dewatering before further processing or disposal.
Coal Preparation Plants
Recovery of fine coal from coal slurry water to improve overall resource utilization.
River Dredging and Slurry Treatment
Rapid separation and dewatering of dredged sand and sediment.
Ceramics and Glass Raw Material Processing
Fine particle classification and moisture reduction for slurry-based raw materials.
Performance Advantages
Exceptional Fine Sand Recovery Efficiency
Designed specifically for fine particles, the system achieves recovery rates exceeding 90% for sand above 0.075 mm, while producing a low-moisture final product.
Highly Integrated, Modular Design
Supplied as a complete skid-mounted unit, requiring minimal civil works. Installation typically involves only slurry inlet, sand discharge, and return-water connections—ideal for production line upgrades.
Significant Reduction in Settling Pond Load
By intercepting the majority of suspended solids, the system dramatically reduces sediment accumulation, extending pond service life and lowering dredging costs.
Water Recycling and Environmental Compliance
Clarified overflow water can be reused directly or after minimal treatment, reducing freshwater consumption and supporting closed-loop water systems.
Fast Return on Investment
Recovered fine sand translates directly into saleable product. In most applications, equipment investment can be recovered within 6–18 months through increased yield and reduced operating costs.
Typical Feed Conditions
Slurry concentration: 5%–30% solids
Optimal recovery particle size: 0.075–2 mm
Adaptable to moderate fluctuations in feed flow and concentration
Conclusion
The XSHS Series Fine Sand Recovery Machine & Integrated Fine Sand Recovery–Dewatering System is not merely an auxiliary device but a strategic process enhancement tool. By recovering lost fine sand, stabilizing product grading, reducing environmental pressure, and improving water utilization, it delivers measurable technical and economic benefits to modern aggregate and mineral processing operations.
For producers seeking higher yield, lower operating costs, and compliance with increasingly strict environmental standards, the XSHS system represents a proven and forward-looking solution.
