Fine Sand Recovery Machine

Product Overview

The fine sand recovery machine can effectively reduce the loss of fine sand and control it within 5%-10%, which is a good solution to the high fineness modulus and high stone powder content of the finished sand in the artificial aggregate processing system. Low puzzle. The fine sand recycling machine is suitable for mud purification, sand and gravel aggregate system of hydropower station, glass raw material processing system, artificial sand production line, and recovery of coarse coal slime in coal preparation plant, etc.

Key Advantages

Efficient Fine Sand Recovery

The hydrocyclone separates and concentrates recoverable fine sand from wash water, helping reduce the loss of valuable material and improve overall plant yield. Actual recovery depends on particle size, slurry concentration, cyclone pressure and operating conditions.

Integrated Dewatering

The concentrated cyclone underflow is discharged onto a high-frequency dewatering screen, which removes excess water and produces a more manageable material for conveying, stockpiling or blending.

Wear-Resistant Wet-Process Components

Polyurethane screen panels and wear-resistant cyclone linings provide improved abrasion resistance when processing manufactured sand, quartz sand and mineral slurry.

Compact Retrofit Design

The recovery system can be connected to the overflow of an existing wheel or spiral sand washer, helping improve fine-sand recovery without replacing the main washing equipment.

Working Principle

Working Principle of Fine Sand Recovery Machine
The sand-water slurry discharged from a sand washer or wet screening circuit enters the collection tank and is pumped under controlled pressure into the hydrocyclone. Inside the hydrocyclone, centrifugal force separates the denser and coarser sand particles from the water and lighter ultrafine material. The concentrated fine-sand slurry leaves through the cyclone underflow and is discharged onto the dewatering screen. High-frequency vibration allows most of the free water and undersize material to pass through the polyurethane screen panels, while the recovered sand moves toward the discharge end. Water passing through the screen returns to the collection tank, while the cyclone overflow is directed to the water-recycling or wastewater-treatment system. Recovery performance and product gradation can be adjusted by controlling the feed pressure, slurry concentration, cyclone specification, apex size and screen aperture.

Frequently Asked Questions

Provide the slurry flow in m³/h, dry solids capacity, particle-size distribution, solids concentration, material density, target recovery size, required product moisture and available pump head. These data are used to select the cyclone, pump, screen area and screen aperture.

No. A fine sand recovery machine normally processes the overflow or wastewater from a wheel or spiral sand washer. It recovers fine particles and removes excess water, but it does not replace the main washing and scrubbing stage.

Common causes include insufficient feed pressure, an unsuitable cyclone diameter or apex, unstable slurry concentration, excessive water flow, worn cyclone liners and particles that are finer than the system’s effective separation range.

Yes. The recovered fine sand, after dewatering on the vibrating screen, typically has a moisture content of 15–25% and meets quality requirements for use in concrete mixing, mortar, and road base applications, provided the particle gradation meets project specifications.

Absolutely. The fine sand recovery machine is designed as a standalone add-on unit that connects to the overflow outlet of an existing spiral or wheel bucket sand washer. Integration requires minimal civil work and can significantly improve the overall yield and economic efficiency of your sand production line. Our engineers will provide a free integration plan based on your current setup.
