Скачать или смотреть 10 inch Sand Pump Dredge Discharge 200m in Uganda for river sand mining

A 10-inch sand pump dredge with a 200-meter discharge capacity is a robust solution for river sand mining in Uganda. Here’s a breakdown of key considerations for such a setup:

1. Dredge Specifications
Pump Size: 10-inch (254mm) discharge diameter

Discharge Distance: Up to 200 meters (horizontal)

Sand Mining Capacity: Typically 200–500 m³/hour, depending on slurry density and pump power.

Engine Power: ~200–400 HP (diesel or electric) to handle high solids content.

Dredging Depth: Usually 5–15 meters, depending on suction head design.

2. Suitable for Ugandan River Conditions
River Sand Mining: Ideal for extracting sand from shallow or moderately deep rivers like the Nile, Katonga, or Mpologoma.

High Solids Handling: Capable of pumping sand, gravel, and mild clay mixtures.

Mobility: Can be mounted on a pontoon/barge or operated from the riverbank.

3. Key Components
Sand Pump: Heavy-duty, wear-resistant impeller and volute for abrasive materials.

Dredge Hull: Floating platform with spuds or anchors for stability.

Pipeline: 10-inch HDPE or steel pipes with flanges for 200m transport.

Excavation System: Cutter head or suction nozzle for efficient sand intake.

Power Source: Diesel engine (common in remote areas) or electric motor (if grid power is available).

4. Advantages in Uganda
Efficient Extraction: Faster than manual or excavator-based methods.

Lower Operational Costs: Reduced labor and fuel consumption compared to truck-based mining.

Environmental Compliance: Minimizes riverbed disturbance if operated responsibly.

5. Challenges & Solutions
Wear & Tear: Use high-chrome pump liners and replaceable impellers.

Clogging: Install a screen or grizzly to filter large debris.

Fuel Supply: Ensure reliable diesel availability or consider solar hybrid systems.

6. Local Suppliers & Regulations
Uganda’s sand mining requires permits from NEMA (National Environment Management Authority).

Local Suppliers: Companies like Mango Tree Group, Kevoton Engineers, or imported Chinese dredges (e.g., Shandong or OCEAN Pump) may offer suitable models.

Conclusion
A 10-inch sand pump dredge with 200m discharge is a cost-effective, high-productivity solution for river sand mining in Uganda. Proper maintenance, compliance with regulations, and selecting the right pump materials will ensure long-term profitability.
