LSYT Series Wheel Sand Washing & Fine Sand Recovery Integrated Machine

The LSYT Series Wheel Sand Washing & Recovery Integrated Machine is an advanced, high-efficiency washing and recycling solution developed for modern aggregate production lines. It represents a significant upgrade over conventional wheel sand washers by seamlessly integrating wheel washing, fine sand recovery, and slurry thickening/dewatering into one compact and highly efficient system.

Traditional wheel sand washers are well known for their large capacity and low operating cost, but they suffer from a major drawback: significant loss of fine sand particles, especially those above 0.075 mm. This not only reduces finished sand yield but also negatively affects particle size distribution and product value. The LSYT Series is engineered to fundamentally solve this problem while retaining the productivity advantages of wheel washing technology.

By combining a wheel washing unit with a dedicated fine sand recovery and dewatering module, the LSYT Series maximizes resource utilization, improves finished sand quality, and significantly reduces environmental impact. It is an ideal solution for aggregate producers seeking higher output, better sand grading, and compliance with increasingly strict environmental standards.

The LSYT Series consists of two main functional sections: the front-end wheel washing unit and the rear-end fine sand recovery and dewatering unit.

1. Wheel Sand Washing Unit

The front section operates similarly to a conventional wheel sand washer. Raw sand enters the washing tank, where the rotating wheel agitates and tumbles the material. Under the combined action of mechanical agitation and water flow, clay, silt, and surface impurities are effectively removed. Clean coarse sand is lifted by the wheel buckets and discharged after preliminary dewatering.

Unlike traditional systems, the overflow water from the washing tank is not discharged directly. Instead, it is routed into the integrated recovery system for further treatment.

2. Fine Sand Recovery and Dewatering Unit

This section is the core value-added module of the LSYT Series.

Slurry Pump
The slurry pump draws the overflow wastewater containing fine sand and mud from the washing tank and delivers it under pressure to the cyclone system.

Hydrocyclone Group
Using centrifugal force, the hydrocyclones rapidly separate fine sand particles (typically ≥0.075 mm) from water and ultra-fine mud. This ensures high recovery efficiency and stable separation performance.

High-Frequency Dewatering Screen
The underflow from the hydrocyclones, consisting of concentrated fine sand slurry, is fed onto a high-frequency linear dewatering screen. Through controlled vibration, the fine sand is efficiently dewatered and deslimed, producing clean sand with very low moisture content.

Return Chute and Mixing System
The recovered fine sand is automatically returned to the finished sand conveyor or mixed with the coarse sand product, resulting in an optimized and continuous particle size distribution.

Clarification Tank / Return Water Tank
The hydrocyclone overflow, mainly water with ultra-fine particles, flows into a bottom clarification tank. After natural settling, clarified water is reused in the washing process, forming a closed-loop water circulation system.

The LSYT Series Wheel Sand Washing & Recovery Integrated Machine is widely used in the following industries:

High-Quality Manufactured Sand Production Lines
Ideal for processing sand produced by vertical shaft impact crushers. It enables precise control of stone powder content and fineness modulus, ensuring compliance with high-performance concrete standards.

Natural Sand Washing and Upgrading
Suitable for river sand, lake sand, and sea sand processing, improving cleanliness while recovering valuable fine particles that would otherwise be lost.

Aggregate Plants with Strict Environmental Requirements
Reduces wastewater discharge and sedimentation load, helping plants meet environmental regulations and green mine standards.

Mining and Tailings Recovery
Applicable to mineral washing processes and secondary recovery of fine sand from tailings.

Concrete Batching Plants and Dry-Mix Mortar Plants
Serves as a sand pretreatment center, delivering stable-quality sand and minimizing moisture fluctuations.

High Fine Sand Recovery Rate

The LSYT Series can recover up to 80–90% of fine sand particles above 0.075 mm that are typically lost in traditional wheel washing systems. This directly increases finished sand yield and improves economic returns.

Optimized Sand Grading and Product Quality

Recovered fine sand is evenly blended with coarse sand, resulting in a continuous and well-graded particle size distribution. The fineness modulus becomes stable and controllable, enhancing the commercial value of the final product.

Compact Design and Cost Efficiency

By integrating washing, recovery, and dewatering into a single unit, the system reduces footprint by 30–50% compared to conventional multi-equipment setups. This lowers civil construction costs, simplifies installation, and reduces overall investment.

Low Moisture Finished Sand

Thanks to high-frequency dewatering, the recovered fine sand has a moisture content as low as 10–15%. The final mixed sand is suitable for direct use in concrete production or dry-mix mortar applications.

Water Saving and Environmental Protection

The closed-loop water circulation design significantly reduces fresh water consumption, typically saving more than 60% compared to traditional systems. Wastewater discharge is minimized, supporting sustainable and environmentally responsible operation.

Stable Operation and High Automation

The integrated control system allows synchronized start-stop operation and centralized monitoring. Fewer transfer points and simplified process flow lead to stable performance and reduced maintenance requirements.

The LSYT Series Wheel Sand Washing & Recovery Integrated Machine is a practical, efficient, and environmentally friendly solution designed for modern aggregate production. By combining high-capacity wheel washing with advanced fine sand recovery technology, it delivers superior sand quality, higher resource utilization, and lower operating costs. It is an ideal choice for producers aiming to upgrade existing lines or build new high-standard sand washing systems with long-term economic and environmental benefits.
