Sand is the second most consumed natural resource on Earth. The construction industry relies on it for concrete, asphalt, and glass. Rivers are a primary source of high-quality sand, but extracting it efficiently and responsibly requires the right equipment. The portable river sand suction dredger from ITECH Co., Ltd is designed to meet this challenge. It combines high pumping capacity with rugged construction to handle abrasive sand while remaining portable enough for rapid deployment.
This article explores the technical details of portable river sand suction dredgers, their applications, and how they compare to other portable suction dredges. We will also discuss how they integrate with portable electric suction dredges, portable pond suction dredges, and portable suction gold dredges.
A portable river sand suction dredger is a floating dredge specifically configured for sand extraction. It typically includes:
High-Chrome Slurry Pump: Resists abrasion from sand particles.
Suction Hose with Strainer: Prevents large rocks from entering.
Floating Pontoon: Supports the pump and engine.
Discharge Pipeline: Transports sand slurry to the shore.
Screening System: Optional vibrating screen to classify sand.
The “portable” aspect means the dredger can be broken down into modules and transported by truck or container. This is essential for river sites that lack road access.
High Output: Moves 50-500 m³/h of sand slurry.
Deep Extraction: Can reach depths of 20-30 meters.
Selective Mining: Targets sand layers without disturbing bedrock.
Environmentally Responsible: Low turbidity, minimal bank damage.
Cost-Effective: Lower operating cost than excavators.
Construction Sand: For concrete and asphalt.
Land Reclamation: Filling and leveling.
Beach Nourishment: Restoring eroded beaches.
Glass Manufacturing: High-purity silica sand.
Gold Mining: As a primary or secondary unit for portable suction gold dredge operations.
Sand particles range from 0.06 mm to 2 mm. The pump must handle these particles without clogging or excessive wear. Key factors:
Impeller Design: Open or semi-open impellers handle larger particles.
Material: High-chrome (Cr26+) is standard. For very abrasive sand, Cr28+Mo is recommended.
Clearance: Larger clearance between impeller and wear plate allows bigger particles to pass.
Speed: Higher speed increases wear; lower speed increases life. VFD control is ideal.
ITECH Co., Ltd uses CFD to optimize impeller geometry for sand. Our pumps achieve up to 85% efficiency.

A construction company in Vietnam needed 500,000 m³ of sand for a highway project. The river site was 15 km from the nearest road, and water depth was 18 meters.
The Solution: ITECH Co., Ltd supplied a portable river sand suction dredger (Model RSD-8) with a high-chrome pump and 200 mm discharge pipeline. The dredger was transported in containers and assembled on-site in 3 days.
The Result:
Average output: 250 t/h.
Project completed in 4 months.
Sand quality met specification.
No bank erosion.
The company later ordered a portable electric suction dredge for a pond project.
Sand is abrasive. Maintenance is critical:
Daily: Inspect suction strainer, check impeller clearance, monitor pump vibration.
Weekly: Grease bearings, inspect wear plate, check hose for leaks.
Monthly: Replace worn impeller if efficiency drops, check motor alignment.
Annually: Overhaul pump, replace all wear parts.
Q1: Can a portable river sand suction dredger be used in saltwater?
A: Yes, but we recommend upgrading to corrosion-resistant materials like duplex stainless steel. ITECH Co., Ltd offers this option.
Q2: How deep can it dredge?
A: Our standard models reach 30 meters. Custom ladders can extend to 50 meters.
Q3: What is the power source?
A: Options include diesel engine, electric motor, or hydraulic drive. Electric models are available for noise-sensitive areas.
Q4: Can it separate sand from gravel?
A: Yes. We offer optional vibrating screens and hydrocyclones for classification.
Q5: Is a permit required?
A: Yes, in most countries. Check with local authorities. ITECH Co., Ltd can provide documentation to support your application.
Q6: Can it be used for gold mining?
A: Yes. Many clients use a portable river sand suction dredger as a primary unit and add a portable suction gold dredge for fine gold recovery.
